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!
