Product Overview
475-3-FM is a series 475 intrinsically safe handheld digital manometer measures positive, negative, or differential pressures of air and natural gases. The dual push pads on the front panel control the on/off, auto zero, and pressure unit selection, allowing for simple operation with no set up needed. When used with a Dwyer® Pitot tube, the Series 475 can also be used as an air velocity gage. Typical applications include monitoring natural gas pressures on boilers and other combustion equipment, air velocity monitoring, when used with a Dwyer® Pitot tube and AV calculator, field calibration of other instruments, monitoring or troubleshooting HVAC systems.
