Single & Dual Pressure Measurement, Electronic Zeroing, ±1.5% Accuracy
The Series 476A Single Pressure Differential Pressure Digital Manometer can be
used to measure low pressures from -20 to 20 in w.c. with ±1.5% FS accuracy.
The Series 478A Single Pressure Differential Pressure Digital Manometer can
be used to measure positive, negative, or differential pressures with ±1.5% full-scale
accuracy. Both units are constructed of an extruded aluminum case for exceptional
durability.

Questions
- Question
- My new Series 476A Digital Manometer scrolls through random numbers and letters like OFL after I tried to zero it. How do I fix it?
- Answer
- The 476A will continually display OFL if it has been over pressurized. Feel free to contact our customer service department to setup an RMA if you’d like it repaired.
- Question
- How does a manometer measure gage and differential pressure?
- Answer
- Manometers simply measure the pressure by indicating the amount of displacement a liquid of known weight undergoes when a force is applied. This concept is best explained through illustrations in our Bulletin D-21 or in our Application Guides on how to use pressure products.
- 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).
