Huma-i White (HI-100) draagbare luchtkwaliteitsmeter. Meet zeer nauwkeurig fijne deeltjes (PM2.5 en PM10). Sensoren gemaakt in Zwitserland.

Zal wel werken, maar geen enkele informatie.ok I found the user manuel.small paper on a small paper and only a hint where to find.Therefore 3 stars for me.

Appareil reçu aujourd'hui 05 mars alors que la livraison était annoncée entre le 20 et le 30 mars ; un très bon point pour le vendeur donc . Ce testeur est compact et l'utilisation est d'une simplicité enfantine ; après l'avoir chargé , un appui court sur le seul bouton de commande le met en marche ; s'affichent alors les trois analyses : particules fines , les ultra fines , et les COV ; un nouvel appui court indique les fines uniquement . Encore un appui et c'est la mesure des ultra fines qui s'affiche . Puis les COV. Je n'ai pas choisi le modèle qui indique la température et le taux d'humidité . Les valeurs affichées sont identiques aux valeurs officielles que je consulte sur AtmoSud ; aujourd'hui nous avons un taux très élevé de microparticules , qui nous viennent du Sahara ; le petit appareil Huma les détecte parfaitement ; je constate d'ailleurs que ce taux est bas à l' intérieur de ma maison ; il m'a suffit par contre d'ouvrir une porte quelques secondes pour que ce taux fasse passer la couleur du voyant au rouge ! je peux aussi constater avec satisfaction que mon taux de COV à l'intérieur est tout à fait acceptable ; ce taux tombe à zéro à l'extérieur , ce qui semble logique . Je suis , en conclusion , très satisfait de cet achat , qui me permet de mieux savoir où j'en suis sur le plan de la pollution dont on nous parle tant , et d'essayer d'agir en cas d'alerte ( ouvrir les fenêtres ou au contraire les laisser fermées pour les problèmes de particules comme aujourd'hui chez moi , changer d'endroit des produits émettant des COV . A ce sujet j'ai posé le testeur près d'un récipient contenant du white-spirit : le taux de COV est monté tout de suite ; ces premiers essais semblent prouver la justesse des mesures ; je ne ressens pas l'utilité pour le moment d'étalonner cet appareil ( appui long de 5 secondes dans un lieu exempt de pollution ) ; reste pour que tout soit parfait une durée de vie de quelques années , mais j'ai tendance , cela n'engage que moi , à avoir confiance dans un produit d'origine coréenne .

I love it; I just put it in my Fjallraven pants' side pocket and it goes everywhere. It has been very instructive to learn just how bad is the air in the New York subway stations! Amazing to think that we have lived so many years exposed to such junk... On the other hand, ignorance is bliss, as they say ;-)

The actual monitor is quite compact : Width * Length * Height ➡️ 4.06 * 9.14 * 3.81 cm ➡️ 1.60 * 3.60 * 3.81 inches. And it’s quite light at 60g approx.The box of contents comes with the Compact Air Quality Monitor Device, a Charging Cable, a Bumper Protective Cover, a strap as well as a six page booklet of instructions.The booklet advises that the device is charged for about an hour or so using a 5V/ 1 Amp Charger plug BEFORE turning it on or using it. My came 2/3rd already charged.I then took the device out into the FRESH AIR for about 5mins or more as recommended by the instruction leaflet.Although not strictly required, as I was keen to monitor nuisance smells in and around my house, I decided to have it calibrated. Having asked the seller and done a Google search I was able to find the HUMATECH Korean Website and under Community ➡️ FAQs, I was able to establish that the way to CALIBRATE the device was TAKE the device out to a well ventilated place with clean air [e.g. a park], then press down on the ON/OFF Button for about 5seconds. The device powers on and the word “Calibration” comes up. After just under TWO MINUTES (2), the device switches off again presumably calibrated!To turn the device on, you just press lightly and briefly on the ON/OFF button. Within a few seconds, the monitor powers on. The device has up to six screens. [You cycle through each screen by pressing gently on the ON/OFF Button which doubles up as a NAVIGATION BUTTON]. The screens of the device that are of great interest to me are the ones that give a figure for VOC (Volatile Organic Compounds such as Second Hand Cigarette Smoke, Formaldehyde, Benzene and Ethylene) as well as the ones for PM2.5 and PM10 (Fine Particulate Matter Dust) and finally the one that gives the temperature and humidity level as well as the temperature in Celsius and Fahrenheit.The instruction booklet gives a detailed list of the six screens. I was interested though to find out that the RESULTS of the Readings are categorised asGood ➡️ LED Code BLUEModerate ➡️ LED Code GREENPoor ➡️ LED Code YELLOWUnhealthy ➡️ LED Code RED.According to the HUMATECH Korean website, when you’re measuring VOCs or Carbon Dioxide (CO2), it takes between 15seconds and 60seconds for the sensor that measures these gases to heat up and it’s normal for the readings to fall until the readings stabilise. I have used the device a few times now and I think it’s fairly accurate in measuring the VOCs (i.e. volatile organic compound which are harmful to human health in high dosage concentrations over a period of time).WHAT I LIKE ABOUT ITa) It is compactb) It is easy to usec) It measures the potentially harmful to human health VOCsd) It gives the temperature and humidity in a room, reminding us to air the rooms!e) It gives a figure for PM2.5 and PM10 (Fine dust Particulate Matter), which can potentially have an adverse effect on our lungs and breathing.f) It’s not the highest grade VOC Air Quality Monitor (which would be very expensive), but I do believe the VOC Results are fairly accurate!NOT SO KEENi) It goes off after 10mins to save the approximate 60min battery life. [By the way it starts to blink AFTER 9mins BEFORE switching itself off after 10mins of being on!].ii) It does NOT give figures for Carbon Dioxide (CO2), only showing it in graphical form as “Good” or “Poor”.iii) As the components circuitry of the machine is working so hard (you hear a faint vibratory sound) to give you its VERY GOOD RESULTS. I think this drains the battery fairly quickly, especially IF you are using the VOC or CO2 setting.iv) It does NOT store the Readings and as soon as you switch off the device, ALL the Readings are lost.v) There’s no way of transferring the readings to another app or of exporting it to email.I was quite concerned that the small battery capacity of the HUMAI Model HI-150 Air Quality Monitor Machine turns itself off after 10mins. And so I researched the matter and found that IF you want the Continual Operation of the device, you can plug it into a POWER SUPPLY or attach it to a Power Bank if you want to be able to carry it around. I chose the latter and I attach it to the excellent ROSS Compact 10000mAH Battery Capacity Power Bank I purchased on Amazon. (I’m yet to write a review!)Would I recommend the above Air Quality Monitor in spite of its drawbacks (i.e. disadvantages)? YesAnd my reasons1. It’s the ONLY Air Quality Monitor that I found at my affordable PRICE POINT that measures VOCs rather than TVOC (Total Volatile Organic Compounds which consists of benign {I.e. not harmful} and harmful substances).2. It appears to have a very good customer back-up service as evidenced by customer services that had a fairly quick turnaround response to the questions I posed to/asked them via Amazon ASK THE SELLER A QUESTION.3. I can get round/overcome the short battery life by connecting it to a CHARGED power bank.Thank you for reading my REVIEW. I hope you have found it HELPFUL.

Simple enough display, and works as it should. I did an elementary accuracy test by taking it outside and testing it then looking up the AQ from the local muni airport. It was within 10 points of accuracy and considering distance and wind, I figured this is close enough. I am in northern California and everything is on fire, smoke is heavy in the air and I wanted to know what my indoor IQ was with all of the shelter in place requirements.All in all, you won't be disappointed.

Updated review 11/15/21I was *finally* able to connect this device to my wifi network. I never got the Android app to work on any of my phones or tablets but then I remembered that Android apps can be run on a Chromebook and Bingo!, the connection went right through and, once the device was added from the Chromebook, it showed up in the app on all my other devices.Anyway, now that the app is actually functioning, I can report that it works well. You have the ability to set notifications when the air quality exceeds your pre-set parameters, which is probably the most useful feature IMO. This monitor continually samples the air and, from the app, I can then review graphs of the air quality, broken down into the individual categories as well as temperature & humidity on a daily and monthly basis to see if there are times of the day when the quality worsens. I was suspicious that I had an air quality issue in my attic room but, apparently not. See app screenshots.I like that the monitor has limited portability in that it can be unplugged from the power source and take it to where I need it, for instance, my workshop when I am working with (mildly) hazardous substances such as spray paint. The battery will last around 50 minutes so it's a useful feature.The monitor now reconnects to my network without difficulty so it appears that once the initial connectivity issues are resolved it works exactly as I had hoped.I feel that I can now recommend this air monitor and, accordingly, I've upgraded my rating to 4 stars with that one star deducted for the initial setup issues.===========================Original review - October 29th, 2021I'd really like to be able to write a meaningful review for this device but I've had huge issues connecting the device/app with my wifi router with endless unclear error messages and then, when I finally managed to do so, yet another error that prevented the device from communicating with their server (I think) with, again, another unclear error message of xxxx (see pics). The issue is not with my wifi since everything else works beautifully.The monitor appears to work in manual mode and it gives air quality readings but I have no way of verifying if they are correct so I guess I have to take them on face value. However, a lot of the functionality depends on the app and usability suffers without it.So, I'll give it 2 stars for now but if there is an app update or the server suddenly starts working, I'll update my review. Disappointed.
