Intrinsically Safe Handheld Digital Manometer (0 - 10.0" W.C.)

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.

Features:

• Rugged aluminum case protects instrument from damage during transport/use
• Large, easy to read LCD and simple operation
• FM approved to be intrinsically safe in hazardous locations, Class 1, Div 2, Groups A, B, C, D, T4 Ta = 70°C

Applications:

• Monitoring natural gas pressures on boilers and other combustion equipment
• Air velocity monitoring, when used with a Dwyer® Pitot tube and AV calculato
• Field calibration of other instruments
• Monitoring or troubleshooting HVAC systems
