Issues with online dust detection

The requirement is that it must not exceed 5mg/M^3. The instrument used has a minimum division of 5 mg/M, a precision of ±5%, and a maximum range of 5000 mg/m. Is this gauge usable?
Your precision is a bit low; the maximum error is 5000*0.05=250. Of course, you can reduce the range, as it shouldn’t exceed 5; you could set it to 10
Although the range can be set, I feel that the precision might still be a bit low. Also, can this gauge be used if it is set to 10?
I’m just using an analogy; if the sensor has good linearity, that’s fine, and in such cases the issue of the sensor’s linearity certainly needs to be taken into account
Why not choose the Fairchild model with a resolution of 0.5 PA? A resolution of 5.0 PA is definitely not enough.
It is recommended not to use it, as the maximum operating range of the sensor is quite large, and its precision level is also high.
For the previous project, it was required to directly measure values not exceeding 5 mg/m3. The accuracy is: plus or minus 1%. The range is: 0–15 mg/m3. Import
