SERIES 1227 DUAL RANGE FLEX-TUBE® U-INCLINED 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

Questions

Question
What's the sample rate of the 475 digital manometer series? Is there an average function of the the past samples?
Answer
The sample rate is 1 reading per second. There is no average function of past samples.
Question
We use series 475-6-FM Mk III digital manometer. What is the recommended calibration interval?
Answer
We do not have an official recommended calibration interval. However, we would suggest checking the calibration at least once or twice a year depending on the applciation and how often the unit is used.
Question
Is there a manometer that is compatible with chlorine gas and sodium hydroxide (bleach)?
Answer
Unfortunately, we do not have any manometers available that can handle chlorine gas or sodium hydroxide (bleach).
Question
I have four Series 475 Mark III Handheld Digital Manometers that we have had for one year. I would like to have them calibrated, but I do not know where to send them. Do you offer a calibration service for the products you sell?
Answer
Yes, we provide NIST calibration for the 475 series both at the time of purchase and afterwards. Please contact one of our customer service representatives at 1-800-872-9141 and provide them with your model number(s).
Question
Does the 475 model work with propane?
Answer
The 475 is compatible with combustible gases and is FM approved.
