Good device – 2.2" LCD Laser Photo Digital Tachometer - Dark Gray + Orange Reviews

Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

Pros:
- Good build quality devices - Storage pouch included - Reflective tape labels on a rotating part
Cons:
- Precision is not very high - Speed values change frequently
Other:
Digital tachometer scale constantly changes speed, but the rotor rotates at a constant speed.
Bottomline:
I used this device to measure the speed of rotation of the rotor viscometer when writing a thesis. Accuracy was pretty low, but I had enough. For use in areas (such as engineering), where high precision is not possible. When measuring the digital tachometer to bring close enough to the rotor. Despite the shortcomings, I pleased with the purchase of a digital tachometer.
