⑴Themarine pressure gauge must be vertical: tighten with a wrench during installation, and do not twist the shell; avoid collision during transportation.

the When the ambient temperature is -40℃-70℃, marine pressure gauge should be used.

⑶ The working environment vibration frequency is less than 25HZ, and the amplitude is no more than 1mm.

During use, the working environment temperature is too high or the atmospheric pressure of the production and use place.

Difference and temperature difference, the indicated value of the marine pressure gauge has not returned to zero or the indicated value is out of tolerance, please adjust it to zero before use.

The use range of Marine pressure gauges should be between 1/3 and 2/3 of the upper limit.

When measuring corrosive gas or high temperature media, please use all stainless steel materials and use safety glass mirrors.

The ocean pressure gauge should be checked frequently (at least once every three months)

A marine pressure gauge for measuring corrosive media is required, and the required conditions of the media should be indicated when ordering.
