Klein Tools Digital Differential Manometer Instructions

�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.
