Manometer Recommendations

[DG77]

Hi,

 

I'm looking for some recommendations for a differential manometer to monitor stove flue vacuum.

 

The stove I've got has a cold vacuum of 0.02"WG and warm vacuum of 0.07"WG.  When I've looked at the offerings on Amazon etc, they don't have the required accuracy at these low values.

 

Any recommendations?

 

Thanks.

The BME280 works in the range you are after, can you cobble up something with one of them and a Raspberry Pi?

He is looking to measure pressure not air pressure.

That is Water Gauge, which is a pressure.

One inch of water is 490.08 Pa.

A pascal is a derived unit of pressure [kg.m^-1.S^-2] or stress [kg.m^-1.S^-2].  Same units however you look at it.

Then we have the Cold or Warm part, which allows for different properties at different temperatures, which makes the BME280 even more suitable.
