NOYAFA NF-604 halogen gas detector, air conditioning fluorine leak detector, automotive refrigerant (freon) leak detector.

Flexible and Bendable Probe: The halogen gas detector is equipped with a 25 cm long probe that can be easily bent along pipes or in confined spaces, allowing for the detection of gas leaks in all directions. The probe can also be bent for practical examination.

High-Sensitivity Sensor: The air conditioner refrigeration leak detector uses a solid-state sampling sensor, which ensures excellent stability, repeatability, fast response, and low power consumption. The probe includes an internal airway filter to effectively reduce contamination from moisture, dust, and dirt, thus ensuring accurate detection results.

3 Alarm Modes: This HVAC leak detector has audible, visual, and vibrating alarm modes. When the gas concentration is below the low limit, the screen displays white without an alarm.

Between the low and high limits, the screen displays white with intermittent vibrations and soft beeps. When the gas concentration exceeds the upper limit, the screen turns red with continuous vibration and a rapid beep. Wide Applications: The halogen gas leak detector is designed to detect halogen gas leaks in various equipment. Precautions: Ensure the air conditioning or refrigeration equipment has sufficient refrigerant during detection. Keep the probe clean to avoid affecting detection results. Allow the device to acclimate to the test environment for at least half an hour. We hope you have an excellent user experience and please feel free to contact us with any questions. We are committed to serving you. Requires 4 AAA batteries*. Not included!
