Content | 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 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. | If you install or connect 3-phase motors and systems, you recognize the importance of verifying the correct motor rotation and wiring phase sequence. Improper connections can cause motors to rotate in reverse direction, potentially damaging the motor and the equipment it is powering. | The Amprobe TMA40-A provides three measurements in one: Air Velocity or volume, Relative Humidity and Temperature. With three ways to view your measurement results. Choose between single point measurement, multiple points up to 99, or the added feature of data logging up to 2400 data points. User sets the measurement interval time from 1 to 200 seconds. The TMA40-A has a flexible cord to position vane where you need to measure. For accurate CFM results, the user simply inputs the area of the air source. TMA40-A ships with USB interface cable, Software CD, hard carrying case and user manual. | 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). | Like the AT-2004, the Amprobe AT-2005 Wire Tracer traces live wires buried or hidden behind walls up to 13 feet (4 m) thick without interrupting power. However, the AT-2005 electrical wire tracer also includes a battery booster that strengthens the signal for more accurately tracing opens and finding wires in walls. The AT-2005 is used for quickly locating breakers, broken wires, neutrals, grounds, shorts and pinpointing ground faults. |
