Product Description
Series 475 Intrinsically Safe Handheld Digital Manometer
(Model #475-1-FM)
(Range 0-20.00" w.c.) (4.982 kPa) (Max. Pressure 10 psig)
*For All 475 Series Models: Ranges from 1" w.c. to 150 psid, ±0.5% Accuracy
The SERIES 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.
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
