| 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. | Test insulation of wires, cables, transformers and electrical motors quickly and easily with this rugged tester. | 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. | The Amprobe SC-3500 4? Signal Clamp for AT-3500 attaches around a buried metallic pipe, cable, or wire to induce a transmitted signal into the feature for active location and tracing. It does not require direct contact with metal to transmit the signal and can transmit signal through insulation on wires and into cable and wire bundles, providing more accurate tracing than locating with just a receiver and transmitter. Accommodates conductors up to 4? in diameter. Transmits a 33 kilohertz (kHz) frequency supplied by the T-3500 Transmitter (included in the AT-3500 kit). | |
