Accuracy: ±1.5% FS

Can this meter be used for butane gas?
The sensor used in our differential manometer is for air pressure use.
It should not apply the gases that have corrosive property.
The butane gas is flammable and liquid type. Which I think that might influence the
sensor



Q&A:

As the accuracy of PM-731 is +/- 1.5% FS and full scale of mmWc is 1500mm =>
1.5% = +/-22.5mmWc or +/- 1.5% FS of reading ex. if reading is 5mmWc, accuracy is
5 x 1.5% = 0.075mm.

Refers to the full scale measurement range multiplied by the maximum error value
ratio.
That is,  error value of the range scale.
For example:

InWC: -60.00 ~ 60.00 error value is 60 X 1.5% = 0.9, so the error is 0.9 InWC range
full of reading,
such as mmWC -1500 ~ 1500 is 1500 X 1.5% = 22.5, error is +/- 22.5 full range of
values !!


When the customer's absolue measurement value  is 100 mmWC, then the error
range is in the acceptance of 77.5 ~ 122.5


In other words, the more a small equivalent measured values​​, the error ratio is
larger!
