This new addition to Klein Tools HVAC product line is an essential tool for every HVAC professional, says Sabrina Kalsi, product manager at Klein Tools. It measures static and differential pressure, as well as identifying pressure drops at filters and pressure loss in ducts. Tapered ports allow for a variety of tubing size attachments, and the magnet on the back allows professionals to free up their hands for easier operation.
The ET180 Digital Differential Manometer from Klein Tools measures air and gas pressure for port 1, port 2, and measures the differential between the ports. Easily toggle between units: inH2O, bar, oz/in2, psi, mbar, kPa, inHg, mmHg, kg/cm2, ftH20, and cmH2O. Large, backlit LCD shows minimum, maximum, and average values. Magnet on back for hands-free operation.
