Feature

●BUNDLE INCLUDES: Dwyer 475-1-FM Handheld Digital Manometer (0-20.00" w.c. (4.982 kPa)) and Rubber Latex Tubing (3/16 inch ID, 9 foot length) Wrist Lanyard, 9V Battery and Operating Instructions.
●PACKED WITH FEATURES: The Dwyer 475 Series Manometer features dual push pads on the front panel to control on-off, auto zero, and pressure unit selection between U.S. and metric units and large, easy-read LCD. Standard hose-barb connections accept 1/8" or 3/16" ID vinyl or rubber tubing.
●INTRINSICALLY SAFE: The Dwyer 475 Series Manometer is FM-approved intrinsically safe for Class 1, Div. 1, Group A, B, C, D, T4 hazardous locations. Ideal for field calibration, monitoring or troubleshooting HVAC systems, clean rooms, fume hoods, isolation cabinets or rooms and a wide range of other low pressure pneumatic systems.
●ACCURATE: Accuracy is +/ - 0.5% of full scale at 60 to 78 degrees F, and +/ - 1.5% full scale at 32 to 60 and 78 to 104 degrees F.
●DWYER QUALITY: Meets the most demanding applications with its solid-state circuitry mounted on a shock-resistant fiberglass epoxy circuit board housed in a durable extruded aluminum case. Dwyer’s unique Dual Sensor System compensates for positional sensitivity- keeping readings stable and accurate regardless of how the meter is held or mounted. Proudly made in USA.
