Questions

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
Can a Slack tube manometer be used for water pressure?
Answer
That style of manometer is to be used with air/gases only. If you need something that reads water pressure, you would want to use something like our Series 490, Series 490A or Series 1211/1212.
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
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
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.
