2、 Shanghai Longtuo reminds you of the precautions for double tube mercury pressure gauges:
1Transportation of Double Tube Mercury Pressure Gauge：Double tube mercury pressure belongs to high-precision instruments containing mercury, which need to be carried by a dedicated person, moved carefully, and not collided.
2Installation of dual tube mercury pressure gaugeThe dual tube mercury pressure gauge supplied by Shanghai Longtuo Instrument should be installed in a pressure chamber with low temperature variation and sufficient light. For stations without a pressure chamber, it can be placed in a specially designed protective box. The pressure gauge should be securely and vertically hung on walls, cement columns, or sturdy wooden columns, and should not be installed near heat sources (heating pipes, stoves), doors and windows, or in places directly exposed to sunlight. No debris shall be piled up inside the pressure chamber. Before installation, the hanging plate or protective box should be firmly fixed in the place where the pressure gauge is to be hung.

3Reading of dual tube mercury pressure gauge:The effective comparative reading of each dual tube mercury pressure gauge shall not be less than5Each reading shall be completed by one person, and the time interval between each reading shall not be less than1hour

4Calibration cycle of dual tube mercury pressure gauge:Shanghai Longtuo reminds you that the calibration cycle of double tube mercury pressure gauges is determined by the environmental conditions and frequency of use, generally not exceeding3Year.
