Dwyer 475-7-FM Intrinsically Safe Handheld Digital ManometerDwyer 475 Intrinsically Safe Handheld Digital Manometer SeriesxApplications 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 systemsThe Dwyer 475 handheld digital manometer measures positive, negative, or differential pressures of air and natural gases in ranges from 1 in w.c. (0.249 kPa) to 150 psid (10.34 bar). 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. This product is FM approved to be intrinsically safe in hazardous locations, Class 1, Div 2, Groups A, B, C, D, T4 Ta = 70degrees-C.The 475 is available in several different pressure ranges.
