Progressive engineering corporation supplies offers safety first gas vigil. This is , an advanced compact electronic unit of the gas leak detectors which that can detect lpg/cng leak and activate the sound and light alarm to make the area of use a safety zone. The alarm device is easy to install, "do-it-yourself`, simple installation type.

Leaked lpg flows in downward direction. In case of cng this alarm is to be fixed at a higher level. The alarm has continuous operation regardless of variation in temperature and humidity. Following are some electrical features of these gas leak detectorseatures: applicable gaslpg/cng; power inputac 220 v [10%, 50 hz; power consumption2.5 w [normal], 3.5 w [activated]; alarm level5% of the lower explosive limit of lpg [1000 ppm]; operating temperature - 20[c to 50[c; audible sound level85 db in alarm mode; warrantyone year [in ideal conditions]; and dimensions4-1/2 x 2-1/2 x 1-1/2.
