UNI-T Digital Tachometer Review - UT373 Mini Tachometer

The UT373 UNI-T digital tachometer is Uni-Trend's budget small size non contact laser tachometer that offers good accuracy, useful features & ease of use.

If you're in the market for an inexpensive, small hand held non contact digital tachometer, or are considering the UNI-T UT373 tach, I hope my little review here can help you decide if the 373 has the features, usability and performance you're looking for in a hand held tachometer.

Accuracy is impressive, build quality is decent, it's easy to use and the UT373 uses inexpensive and easy to source AAA batteries. The large backlit high contrast LCD display is easy to see and read in both low light and bright sunshine.

The UT373's non contact RPM light sensor can be used with either the built in laser or an external light source making it very adaptable in multiple applications. It even has a counter feature which adds more versatility over and above that of an RPM meter.

It works great on smaller RC helicopters where you can safely tach the main or tail rotors. Checking RPM on airplane or quad copter propellers is easily done as well. With an RPM range up to 99,999, about the only thing out of the UT373's useful RC application checking range is model turbine engines.

Of course, RC is just one area where a nice little digital tachometer comes in handy. These non contact laser tachometers work well in all sorts of applications from automotive, to turning machinery, to power equipment.
