1. Introduction
The HD02 Refrigerant Halogen Leak Detector is a versatile and high-precision instrument designed for detecting leaks of various refrigerant gases, including R22, R32, and R134a. It features a highly sensitive sensor, fast response time, and a flexible probe for easy access to hard-to-reach areas. This detector is equipped with a triple alarm system (sound, backlight, and on-screen display) to clearly indicate the presence and intensity of a leak.
Its multi-purpose design makes it suitable for a wide range of applications, including industrial inspections, household appliance maintenance, and professional refrigeration equipment installation and servicing. The device also offers temperature conversion between Celsius and Fahrenheit for user convenience.
2. Safety Information
Please read and understand all safety instructions before operating the device. Failure to follow these instructions may result in electric shock, fire, or serious injury.

6. Setup
- Charging the Device: Connect the provided charging cable to the charging port (7) at the bottom of the detector and plug the other end into a suitable USB power source. The battery indicator on the display screen (3) will show charging status. Ensure the device is fully charged before its first use.
- Powering On: Press and hold the Power button (6) for a few seconds until the display screen (3) illuminates.
- Initial Self-Test: The detector will perform a brief self-test upon startup. Wait for this process to complete before proceeding.
- Selecting Temperature Units (Optional): If desired, press the °C/°F button (5) to toggle between Celsius and Fahrenheit temperature displays.
- Adjusting Sensitivity (Optional): Press the SET button (8) to cycle through sensitivity levels (e.g., High, Low). The current sensitivity will be indicated on the display screen (3). Start with a higher sensitivity for general scanning and reduce it for pinpointing small leaks.
7. Operating Instructions
Follow these steps to effectively use your HD02 leak detector:
- Preparation: Ensure the detector is powered on and has completed its self-test. Select the appropriate sensitivity level for your task.
- Scanning for Leaks: Slowly move the flexible probe (2) with the sensor tip (1) around the suspected leak area. Maintain a steady, slow pace (e.g., 1-2 inches per second) to allow the sensor to react.
- Interpreting Alarms:
The HD02 provides triple alarms: sound, red backlight, and an intensifying screen display. - Audible Alarm: The device will emit a beeping sound, which intensifies as the leak concentration increases.
- Visual Alarm (Backlight): The display backlight will turn red when a leak is detected.
- Screen Display: The PPM value on the display screen (3) will increase, and a simulation bar will gradually intensify, indicating the relative leak size.
- Pinpointing the Leak: Once a leak is detected, move the probe back and forth over the area to pinpoint the exact source. You may need to reduce the sensitivity using the SET button (8) to narrow down the leak location more precisely.
- Auto Power Off (APO): The device may have an automatic power-off function to conserve battery. Press the APO button (4) to activate or deactivate this feature as needed.
- Turning Off: After use, press and hold the Power button (6) until the display turns off.
8. Maintenance
- Cleaning: Wipe the exterior of the detector with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the sensor tip clean and free from debris.
- Sensor Care: The sensor is a critical component. Avoid exposing it to harsh chemicals or physical impact. If detection accuracy degrades over time, the sensor may need replacement by a qualified technician.
- Storage: Store the detector in its protective storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery: Recharge the battery regularly, even if the device is not in frequent use, to maintain battery health.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery; Faulty power button | Charge the device fully. If problem persists, contact support. |
| No detection or inconsistent readings | Sensor dirty or damaged; Incorrect sensitivity setting; Air currents affecting detection | Clean the sensor tip. Adjust sensitivity. Minimize air movement around the detection area. |
| False alarms | High background gas concentration; Sensor contamination; High sensitivity setting | Move to a fresh air environment to recalibrate. Clean the sensor. Reduce sensitivity. |
| Display not working | Low battery; Device malfunction | Charge the device. If issue persists, contact support. |
10. User Tips
- Pre-Test Calibration: Before each use, it's good practice to move the detector to a clean air environment for a few seconds to allow it to stabilize and establish a baseline.
- Slow and Steady: When scanning for leaks, move the probe very slowly. Rapid movement can cause the detector to miss small leaks.
- Systematic Approach: Work systematically around pipes, joints, and components. Start from the highest point and work downwards, as many refrigerants are heavier than air and will sink.
- Temperature Influence: Be aware that extreme temperature changes can affect sensor performance. Allow the detector to acclimate to the ambient temperature of the testing environment.
