BG40 Gas Detector

The storage and use of combustible gases, such as natural gas, methane, ethane and propane, are among the risks of everyday life that should not be underestimated. For this reason, gas cartridges and liquid gas containers in the household or on the boat, as well as gas pipes and fittings, should be regularly checked for their tightness with a gas detector such as the BG40.

Thanks to its high sensitivity, the compact gas indicator BG40 records even the smallest gas leaks within just two seconds – and warns with a sensitivity of less than 10 ppm even from the lowest gas concentrations by means of optical, acoustic and vibration alarms. The acoustic alarm signals an increasing intensity of the exiting gas with increasing frequency and loudness.

A 40 cm (15.75″) flexible tubing probe allows the detection and identification of a leak in hard-to-reach and constricted areas. The gas detector is equipped with a backlit LCD display, which allows the measured ppm values to be read fast and easily at any time even in unfavorable light conditions. Further, the so-called Lower Explosion Level, abbreviated LEL, which defines the minimum gas concentration in the air at which an explosion is possible, is displayed.

Benefits for practice:

  • Gas warning device and gas detector in one
  • Optical, acoustic and vibration alarm
  • Alarm frequency and volume relative to gas concentration
  • Large, easy-to-read display with additional indicator-display
  • Backlit LCD display
  • Automatic shutdown
  • Soft touch function buttons
  • 1/4-inch tripod thread
  • Simple one-hand operation
  • Optimal value for money
  • Semi-flexible, 40 cm long gooseneck-probe for the examination of hard-to-reach places

The BG40 reliably detects combustible gases such as natural gas, methane, ethane, propane, butane, hexane, ethylene, acetaldehyde, formaldehyde, toluene, P-xylene, acetone, alcohol, benzene, ammonia, steam, carbon monoxide, gasoline and hydrogen sulfide.
