D-Tek 3 refrigerant leak detector with field replaceable infrared sensor, flexible probe and rubberised grip is sensitive to HCFCs, HFCs, HFOs, blends (including A2Ls), ammonia, SF6 and all standard refrigerants. Variable intensity audible signal grows stronger as the leak is approached, fainter as the probe is moved away. Yellow LEDs light progressively to show leak magnitude. Power indicator LED changes from Green through Orange to Red when charge is required. sensitivity button allows reduced sensitivity when close to the leak, making it easier to pinpoint its exact source. High efficiency pump maintains continual flow of air through the sensor for instantaneous reaction to ambient refrigerant.
Unit includes Li-ion rechargeable battery, USB charging lead, AC wall charger and 2 spare filters.
