Optional item:
* If used for medium with large pressure pulse can be selected: buffer bend or damper.
* If the pressure gauge needs to be operated without shutdown when not in use or replaced, the optional pressure gauge switch of the pressure gauge and the measured medium must be disconnected.
* For pipe mounting (AT), 45# steel welded base, pressure gauge switch and buffer bend can be supplied as a complete set.
* For panel mounting (DT or ET), optional pressure gauge hose and pressure gauge switch are available.

Applicable media:
Precision pressure gauges can be used to measure all fluid media that do not react with copper alloy, and do not crystallize, do not solidify, have no explosion risk, and are non-toxic and non-highly viscous.
