Series 476A Single Pressure & Series 478A Digital Manometer

Series 476A Single Pressure & Series 478A Digital Manometer

Series 475 Intrinsically Safe Handheld Digital Manometer

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.

NIST CALIBRATION available in Product Configurator.

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
