About This Heated Diode Sensor: Compared to traditional sensors, the results are also more accurate for all halogenated refrigerants. TFT Screen: First leak detector with a TFT screen that gives more clear and easy readings on sensitivities, leakage alerts, battery levels and other key info during operations. Higher Sensitivity: Adjustable sensitivity with High/Medium/Low levels and the maximum sensitivity is up to 0.1oz/yr. Quick Operation: The two corresponding buttons on the front allows quick adjustment to sensitivities or to mute buzzer directly, very easy to operate. Detecting All Halogenated Gases: It can detect all kinds of halogen refrigerants including CFCs, HFCs, HCFCs, HCs, HFOs and mixed refrigerants such as R11/R22/R404a/R410a/R600a/R1234yf and Blends such as AZ-50, HP62, MP39 etc. and response within 1s. We offer 7*24 services and a one-year warranty for the gas leak detector.
