VZ7291 Explosive Gas Detector Sensor Meter

Portable meter VZ7291 is designed for checking gas leaks, detecting and locating damage to gas installations and appliances, checking the tightness of liquid gas cylinders, etc. Simple operation allows you to quickly and accurately locate leaks. Flexible probe with a length of 450 mm allows easy access to awkward places. The device has acoustic signaling and a visual, six-stage LED leak detection scale. If the situation requires that the test be carried out in silence or the ambient noise is high enough to make it difficult to hear the acoustic signaling, the test can be performed using headphones. The meter can be powered by four alkaline batteries or via an AC adapter. It has a low-voltage power supply LED indication.

According to the Official Gazette No. 40 item 275 Regulation of the Minister of Transport and Construction of February 10, 2006 (on detailed requirements for stations conducting technical tests of vehicles), this type of device should be on the equipment of each vehicle inspection station.

Application:

At vehicle inspection stations (the device meets ITS requirements), at propane-butane gas sales outlets, establishments engaged in the installation and servicing of gas installations in cars, for technical services to inspect gas installations in residential buildings, to inspect connections of domestic gas receivers.
