Description

Dwyer-Series 475 Mark III Intrinsically Safe Handheld Digital Manometer (0 - 1.0 IWC)

This SERIES 475 Mark III Handheld Digital Manometer measures positive, negative, or differential pressures of air and natural gases in ranges of +/-1 in w.c. (0.249 kPa) , max pressure 5 PSIG (34 KPa)

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 Pitot tube, the Series 475 can also be used as an air velocity gage.

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

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
