【𝐇𝐢𝐠𝐡 𝐒𝐞𝐧𝐬𝐢𝐭𝐢𝐯𝐢𝐭𝐲 𝐚𝐧𝐝 𝐀𝐝𝐣𝐮𝐬𝐭𝐚𝐛𝐥𝐞】Compared with traditional freon leak detectors, ALD-200 PRO ac leak detector sniffer is more accurate and less susceptible to interference from other gases. 3 modes of sensitivity with maximum sensitivity up to 0.14oz./yr. 16 inch sensor probes of the hvac leak detector that allows you to reach hard-to-reach areas. 【𝐀𝐮𝐝𝐢𝐛𝐥𝐞 & 𝐕𝐢𝐬𝐮𝐚𝐥 𝐀𝐥𝐚𝐫𝐦 𝐰𝐢𝐭𝐡 𝐌𝐮𝐭𝐞 𝐅𝐮𝐧𝐜𝐭𝐢𝐨𝐧】When the leakage is detected, the leak detector hvac screen will show the leakage level, and more rapidly it beeps. Press the MUTE button to turn on/off the buzzer. 【𝐔𝐬𝐞𝐫-𝐟𝐫𝐢𝐞𝐧𝐝𝐥𝐲 𝐃𝐞𝐬𝐢𝐠𝐧】Reset Function of the ac leak detector allows you to identify leaks without the false positives of the background concentration. Peak function records the max. value of leaks. The built-in 3000mAh rechargeable battery of the freon tester is more environmentally friendly and provides continuous 6 hours working time. 【𝐃𝐞𝐭𝐞𝐜𝐭 𝐀𝐥𝐥 𝐑𝐞𝐟𝐫𝐢𝐠𝐞𝐫𝐚𝐧𝐭 & 𝐂𝐨𝐦𝐛𝐮𝐬𝐭𝐢𝐛𝐥𝐞 𝐆𝐚𝐬𝐞𝐬】The leak detector hvac detects [CFCs: R11,R12,R13,R113,R114,R115,R500,R502,R503] [HCFCs: R22,R123,R124,R141b,R142b,R401A,R401B,R402A,R402B,R408A,R409A] [HFCs: R32,R125,R134a,R143a,R152a,R404A,R407C,R410A,R410B,R417A,R422D,R427A,R438A,R448A,R449A,R452B, R453A, R507] [HFOs: R1234yf, R1234ze(E), R1233zd(E), R1336mzz(Z), R514A, R1224yd(Z), R1243zf] [Blends: R401A, R404A, R407C, R410A, R507, AZ-50 (R507), HP62 (R404A), MP39 (R401A), NU-22 (R422D)] [PFC: PFC-14, PFC-116, PFC-218, etc] [HCs(Hydrocarbon): R50, R290, R600a etc.][5%hydrogen/95% nitrogen Racer Gas] [A2, A2L, A3 refrigerants ] Propane Methane Ethane 【𝐂𝐨𝐥𝐨𝐫 𝐆𝐫𝐚𝐩𝐡𝐢𝐜 𝐃𝐢𝐬𝐩𝐥𝐚𝐲 】The r134a leak detector features a new color graphic display that helps locate leaks using a unique bar graph mode to show the amount of gas detected and changes colors as it gets closer to the leak., Weight: 0.871266859424 Pounds, Manufacturer: Therm La Mode
