The pressure gauges are defined as “pressure accessories”.The volume of the “pressure-bearing housings” of pressure gauges is < 0.1 L.The pressure gauges carry CE marking for fluid group 1 per annex II, diagram 1 when their permissible working pressure is > 200 bar .Instruments that do not carry the mark are manufactured per article 4, paragraph 3 “sound engineering practice”
Fixture of our fire fighting pressure gauges is made of metal .

Pressure Gauge Installation Precautions:
1. Before installing the Firefighting Pressure Gauge on equipment, check whether the meter head and the measuring hole are clean. During use, the pipeline should be kept clean.
2. After the installation is completed, confirm whether the range matches the pressure range, so as to avoid pressure overload or low resolution.
3. The on-site use conditions should meet the requirements of the technical parameters of the instrument. Correct selection of the instrument range, the measured pressure.The force cannot exceed the upper and lower limits of the instrument, and there should be a sufficient overpressure safety margin.
4. The temperature of the measured medium should not exceed the working temperature range of the instrument, and the sealing and vibration resistance performance of the instrument should also be ensured when used in corrosion and vibration places.
5. The instrument is a vertical downward direct installation type, which can be directly installed on the pressure interface of the pipeline under test. During installation, avoid the formation of "closed pressure" between the instrument connection thread and the valve in front of the meter (observe the indication value, and pay attention to the pressure response time) , if the pressure is formed, it should be eliminated in time, otherwise it will cause damage to the measuring element and medium leakage.
