DANOPLUS Digitale TDS Meter, Professioneel 2-in-1 TDS, EC Temperatuur Waterkwaliteit Tester, Ideale ppm meter voor Water, Aquariums, enz. (pH-Elektrode)

Le prix très compétitif a déclenché mon achat mais dommage, la tête de la sonde faisant 20,5mm elle de passe pas dans le support de sonde de mon système de filtration piscine "zodiac expert" (régulateur auto de PH) qui fait 16mm.Le retour s'est passé sans problème après explication avec le fournisseur très à l'écoute.

It's good. Enough sturdy and easy to use.

The pH functionality is a little slow but fairly accurate once calibrated (+/- 0.2pH from 4 to 10 compared to my Apera). I didn't buy it for this, though.For some unexplainable reason, this meter was the only one I've found (at any price point) to display TDS / Salinity readings up to 25% .. and it does so very accurately! I needed to test a KCl storage solution I'd prepared for my Apera, and it came in exactly where I'd calculated. I compared against a reference solution, and the probe was dead on.One thing that's a little annoying is that there's no rubber o-ring on the probe or cap, so you need to keep it vertical if using storage solution. This raises questions about the pH probe's longevity, but time will tell. If your primary interest is in measuring pH I'd look elsewhere.But, if you need to measure salinity / TDC / EC at very high levels, this is the only probe on the market that will do that!

Notice d instruction en anglais donc à acheter si vous maîtriser suffisamment cette langue son usage.

Snabb leverans och ett bra pris på en mycket exakt PH mätare.Lång sladd vilket underlättade monteringen enormt.
