Tachometers are used in HVAC/R to measure RPM or total count (total number of revolutions) on air conditioning and heating system blower motors and fans. An RPM reading out of spec can tell you that your wiring may need attention or that a motor is not running at maximum efficiency. Our non-contact laser tachometer is simple to use and gives you accurate readings up to 4-feet away.
