| Content | The Amprobe TMA-21HW Hotwire anemometer technology eliminates the use of bearings and rotating parts. When compared to standard bearing type probes, the compact Amprobe hotwire sensor is more reliable (no mechanical moving parts) and allows for easier access to duct and confined spaces. The Amprobe TMA-21HW Hotwire anemometer measures air flow volume and velocity, it features a telescopic probe for positioning the sensor, and is used by HVAC/R technicians to measure wind flow and temperature in air conditioning systems. | Eliminate downtime, predict the lifetime of equipment and reduce safety hazards with the Amprobe AMB-55 Insulation Resistance Tester that tests voltage and step voltage to 5,500 V. You can accurately test cables, transformers, motors, surge arrestors and generators in noisy environments such as high voltage switchyards. It also boasts built-in noise rejection filters and shielded test leads to provide high EMI immunity | | TEST LEAD SET FOR INSULATION RESISTANCE TESTERS | The Amprobe TACH20 Hand-held Tachometer accurately measures rotational or surface speed as well as length. It comes with a large LCD display that allows the user to easily read the measurement. It also has a built in memory function that permits automatic storage of maximum, minimum, average values plus the last measurement displayed. | Universal, economical tachometer measuring rotational or surface speed either in contact or non-contact way. Widely used to measure rotational speed of motors, conveyer belts and other moving or rotating systems. |
