性確保の効果は大きい。Gas leaks on the gas piping from the gas piping outlet to each individual gas combustion appliance can be detected before the appliance is fired. In particular, gas fan heaters and the like used indoors are carried from room to room, and gas pipes must be installed each time, so there is a high probability that mistakes will occur during the work. moreover,
Since rubber hoses and the like have a short service life and are prone to cracking and gas leakage, the use of this device has a great effect on ensuring safety.
