Stress is a common industrial process parameters, the application of precision pressure gauge is also more common than other instruments. Precision pressure gauge used dozens of comparable parameters have as many as can be seen on the meter face is the selection of parameters should be first than right. This form prepared for the convenience of you peers, it can be done on the 0.4, 0.25, 0.16 Precision pressure gauge range, sub-grid scale number, the smallest sub-cell values, tolerance values of parameters of each comparison. You can take advantage of this form to your precision pressure gauge preferred.

Precision pressure gauge not only the standard gauge, pressure gauge not only their technical parameters parameters.
Include: level of precision pressure gauge accuracy, precision pressure gauge measuring range, precision dial pressure gauge of the total number of sub-grid, precision pressure gauge the value of the smallest sub-grid, precision pressure gauge of tolerance values, precision pressure gauge connection threads, precision the work of media such as pressure gauges. are the key parameters of precision pressure gauge. You can use this table to provide flexibility in the technical parameters, selecting the best choice you need precision pressure gauge (standard gauge).
