Instrument accuracy class
Thread Content
Hello, everyone! When purchasing instruments, how can we ensure the accuracy of their measurements? Is it to choose the appropriate gauge range and accuracy class? Is it true that the lower the accuracy grade of the instrument, the more accurate the measurements? Solve!
Generally, for selecting the range of a gauge: the measured value of the medium is usually around 2/3 of the gauge’s range, while the accuracy class indicates the maximum allowable error. A seismic pressure gauge with an accuracy class of 1.6 and a range of 0~0.6 MPa is generally used for pump heads with a pressure of around 4 kilograms, offering an accuracy of ±9.6 KPa.
It is necessary to choose an appropriate range and accuracy; the manufacturer’s quality, reputation, and track record are also very important.....
