Digitaal Toerenteller 3~100000RPM Contactloos En Contact Bereik from 3 to 19,999 RPM Handbediend Snelheid Meter met Achtergrondverlichting, Max/Min/AVG RPM voor Automobiel Diagnostiek, HVAC Systemen

Good tachometer. Works well in contact and non-contact modes.

Der Geschwindigkeitsmesser überzeugt schon beim Auspacken durch eine sehr robuste Bauweise. Die Bedienung ist einfach, das Display lässt sich sehr gut ablesen, auch wenn die Lichtverhältnisse nicht die Besten sind. Man kann entweder kontaktlos messen oder mit einer der vier mitgelieferten Sonden. Die Messergebnisse können sich sehen lassen und sind sehr genau. Preis-/Leistungsverhältnis stimmt.

Handleiding is zeer beperkt waardoor even moeten zoeken hoe toestel gebruikt moet worden. Verder werkt alles perfect. Ideaal meettoestel voor hobbist.

This digital tachometer seems like a decent unit, though the instructions could be a bit clearer and more detailed for first-time users.-The direct contact measurement can be tricky to figure out and requires adjusting some additional settings to get it working properly.-The laser measurement with reflective tape is the most practical method, but you’ll need to hold the unit very steadily to avoid inaccurate readings.-The pointed contact tips are a nice touch and work well as long as you can gently hold them against a rotating shaft to maintain a proper 1:1 ratio.Overall, it’s a good addition to a DIYer’s toolbox at a reasonable price. For professional applications, though, I’d recommend opting for a higher-quality unit for better accuracy and ease of use.

This worked pretty well, giving me a reading in line with what I expected to see from a fan. Taking measurements could be a bit simpler though. You have to hold one button to get the backlight on, then hold another to turn on the laser and start the measurements. A single "Measure" button would make more sense. I tried to use it without the included reflective tape, and it didn't even register rotation, so I recommend just using it. This comes with a lot of it, and you only need a little square to get it to register. The included case is decent for keeping everything organized too.
