Gas Leakage Detector | Reliable Combustible Gas Tester with Sound & Light Alarm for Natural Gas Leak Detection - Essential Safety Device for Home and Industry most accurate home scale Impedance Range: up to 32This product is absolutely GREAT!!!! It detected 4 Small Leaks of natural gas in my Boiler Room that I couldn't even smell. I thought it was inaccurate and so I used Windex to check where it showed the leaks since I couldn't smell any thing. Behold, It Was Accurate! I had 4 leaks! Now they are repaired and it detects nothing and neither does the Windex! If you use it correctly, IT WORKS GREAT!! Michael D. Locates Combustible & Explosive Gas Leaks This
