- 【Precise Leak Detection】: Adopt the most advanced sensing technology and microprocessor chips to help users accurately locate the leakage points of various refrigerants, such as CFC, HFC, HCFCs, HC, HFO, etc.
- 【Adjustment of Sensitivity】: The unit features vari-speed sensitvity adjustment and can be adjusted during the course of detecting. Clockwise adjusting means high sensitivity and in reverse means low.
- 【Leak Alarm】: When the leaked gas is detected, the audible tone will change to a "siren" typesound. More refrigerant, more siren. At the same time, Indicator light is flashing quickly.
- 【KIT Included】: This kit includes a UV lamp and UV resistant glasses, equipped with 3 long-lasting AAA batteries. UV lamp can help you locate leaks in your car's air conditioning system. High quality plastic safety glasses ensure safe Freon leak testing in dark places and block UV rays to protect your eyes.
- 【Buy with Confidence】: We provide you with 100% satisfaction guarantee. If there is any problem with your refrigerant leakage detector, please contact us, and we will provide you with return, exchange and repair.
- 【Flexible Bendable Probe】:RAINLEOTI halogen gas detector is equipped with a 25cm long probe that can easily bend along pipes or in enclosed spaces, allowing detection of gas leaks in any direction. The probe can be bent at will for convenient inspection.
- 【High Sensitivity Sensor】:The RAINLEOTI air condition refrigeration leak detector utilizes a semiconductor sampling sensor, providing excellent stability, reproducibility, fast response, and lower power consumption. The probe includes an internal air path filter to efficiently reduce interference from moisture, dust, and dirt, ensuring precise detection results.
- 【3 Alarm Modes】:This HVAC leak detector features sound, light, and vibration alarm modes. When gas concentration is < the low limit, the screen displays white with no alarm. When between the low and high limits, the screen displays white with intermittent vibration and gentle beeping. When gas concentration exceeds the high limit, the screen shows red with continuous vibration and rapid beeping. High and low limit alarm values are customizable (note: high limit must be higher than low limit).
- 【Wide Applications】:The RAINLEOTI halogen gas leak detector is designed for detecting halogen gas leaks in various equipment. It is suitable for refrigeration and air conditioning systems to detect refrigerant leaks, fire extinguisher systems using halogenated alkanes, chemical facilities to monitor leaks of halogenated solvents and chemicals, laboratories to detect accidental releases of halogen compounds for safe operation, and environmental monitoring for atmospheric halogen gas concentration. It can detect CFCs, HCFCs, and HFCs.
- 【Precautions】:Ensure air conditioning or refrigeration equipment has sufficient refrigerant during detection. Keep the probe clean to avoid affecting detection results. Allow the device to acclimate in the testing environment for at least half an hour. We wish you to enjoy an excellent user experience, and feel free to contact us for any inquiries. We are dedicated to serving you.
