Freon Refrigerant Leak Detector, Liquid Halogen Gas Detector for Highly Sensitive Air Conditioning Systems

Flexible and Bendable Probe: The halogen gas detector features a 25cm long probe that can be easily bent along pipes or in tight spaces, allowing gas leak detection in all directions. The probe can also be bent for practical testing. Highly Sensitivity Sensor: The refrigerant leak detector for air conditioning systems uses a semiconductor sampling sensor, ensuring excellent stability, repeatability, rapid response times, and low power consumption. The probe is equipped with an internal air path filter that effectively reduces contamination from moisture, dust, and dirt, thus ensuring accurate measurement results. Three Alarm Modes: This leak detector for heating, ventilation, and air conditioning (HVAC) systems is equipped with audible, visual, and vibration alarms. If the gas concentration is below the lower limit, the display will show white without triggering an alarm. Between the lower and upper limits, the display will show white, accompanied by intermittent vibrations and silent beeps. If the gas concentration exceeds the upper limit, the display will turn red, accompanied by continuous vibration and rapid beeps. Wide Range of Applications: This halogen gas leak detector is designed to detect halogen gas leaks in various devices. Precautions: Make sure the air conditioner or refrigeration unit contains sufficient refrigerant during measurement. Keep the probe clean to ensure accurate readings. Allow the device to acclimatize to the test environment for at least half an hour. We wish you a great user experience and will be happy to answer any questions you may have.
