The SERIES 475 Handheld Digital Manometer measures positive, negative, or differential pressures of air and natural gases in ranges from 0 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.
Product Applications: 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.
