Many people don't know what the precision level 1.6 of a pressure gauge actually means? Let's explain in detail below:
Firstly, the accuracy of the pressure gauge measurement results is called the accuracy of the pressure gauge. Accuracy level is one of the important indicators for measuring the quality of pressure gauges.
Pressure gauges can be divided into precision pressure gauges and general pressure gauges based on their measurement accuracy. The measurement accuracy levels of precision pressure gauges are 0.1, 0.16, 0.25, 0.4, and 0.05, respectively; The measurement accuracy levels of general pressure gauges are 1.0, 1.6, 2.5, and 4, respectively Level 0.
The accuracy level of a pressure gauge is expressed as the percentage of allowable error to the pressure gauge range, generally divided into seven levels: 1, 2, 3, and 4 (levels 3 and 4 are not used on boilers). The smaller the value, the higher the accuracy.

So, the actual error of a pressure gauge is not only related to its accuracy, but also to the range size of the pressure gauge. When the range is the same, the higher the accuracy (i.e. the smaller the number), the smaller the allowable error of the pressure gauge. When the accuracy is the same, the larger the range, the greater the error of the pressure gauge.
