Protmex PT6208A Digital Contact Tachometer, Contact Measurement Speed Tach Meter, 50-19999RPM Speed Meter, Contact Tach RPM Meter with 100 Groups Data Logging, Data Hold, Max/Min/AVG, Backlight

Worked for what I needed. Had to check speed of a exhaust fan, was very simple because the kit comes with multiple size and shaped tips that fit on different pulleys or motor shafts. Cant beat a cheap tool that does what its supposed to.

One thing about this tachometer. Do not throw away the manual!! You will need it if you want to measure distance over time. It’s a crazy set of instructions in order to activate the 6” wheel which is the only way to measure distance over time. Other than that it’s pretty simple to use.

Works as expected

Some measurement modes do not work at all: m/min, m/sec, ft/sec. Other measurement modes did work: ft/min, in/min, and Contact (RPM). At this price point I don't expect much, but I do expect it to function as advertised when it arrives. Followed (poorly written / translated) instructions and tried metric 'perimeter' setting (0.1m) with metric measurement modes, with no luck. Measurement mode ft/sec did not work with standard perimeter settings (6" or 12"). Tried all perimeter settings with all measurement modes, never did get readings for measurement modes m/min, m/sec, ft/sec. To be clear, in my opinion this appears to be a design / firmware issue and not a one-off defective unit. Of the modes that did work, I didn't have another method with which to compare accuracy. Backlit screen is bright. Unit housing appears reasonably solid for an entry-level device. However the measurement shaft bearing is exposed at the top of the unit (see photo), and dust/dirt will ruin any bearing over time, so the device not designed for typical manufacturing or automotive environments. Also note that the orange areas are a coating on the plastic housing, not a thick silicone boot / shell. The coating provides good grip and visibility,and minimal impact protection. Measuring tips are plastic, and rubber wheels / tips are not attached with adhesive / epoxy so they could become detached and lost. Unit came with a zippered canvas pouch.

Great quality. Working perfectly.

Works well

Price is great but the controls to modify settings for switching between attachments and modes (units/ rpm vs fpm) is very frustrating. Since i use it only very infrequently I’m satisfied for the price but if you will use often buy something else. Checked the speed with the .1m attachment vs a belt conveyor on a VFD and it was accurate.

I needed an accurate tachometer to set the RPMs of an engine powered pump. I had an old analog (dial) one that started giving erratic readings, so I thought I'd try this one. Simple to use, just turn it on, and read the RPMs, and it 'holds' the latest reading on the screen for a few seconds. You can also set it to read things like maximum RPM, and with the right accessory, can even read linear FPM for things like a conveyor belt. My biggest nit to pick, is that it seems a bit delicate when compared to my old all-metal one, especially the tips that engage the shaft, (old one was metal with a rubber tip, this one is plastic and also smaller) but it has worked well enough. For the couple times a year I'll be using it, it is fine. Came with a carrying case that keeps all the pieces together. I got this one because it had an extension for the tip/shaft to be able to engage a shaft within a recess, and I'm glad I did. With the regular tip and no extension, it does not have a lot of reach.

Excellent product for the money! Excelente seller!

Ben fatto ma forse un po' troppo complesso da usare e un bel oggetto speravo un po' più semplice invece ha tantissime funzioni che non so neanche se userò consiglio perché e un bel prodotto e di ottima qualità

The one I received did not work at all. I’d also consider the method of measuring suspect as it has several friction wheels and the variance of diameter between the friction wheel and the item being measured will mean the rpm will need to be calculated. As the one I got did not work I did not have the opportunity to test this out.

Il prodotto all'apparenza si presenta ben fatto Il problema é che non funziona come dovrebbe Nel mio caso l'utilizzo principale sarebbe stato di misurare velocitá di nastri trasportatori. Con la rotella 0.1 settata , il contagiri ( rpm ) funziona ma le misure in metri/secondo e metri/minuto rimangono sempre a zero. Da qualche segno di vita impostando la rotella 6" e misurando in grandezze imperiali ma che a me non interessano. Contattata assistenza Amazon ha sollecitamente risposto per un eventuale reso. Il produttore invece ancora no dopo una settimana ......

Ottimo prodotto, ha una consistenza solida gli accessori giusti e funziona bene. Spedizione puntuale come sempre.
