• Built to last with a 10-year sensor life
• TFT LCD screen provides a clear visual confirmation of the leak location
• Audible and visual notification for leak detection
• Works on all halogenated refrigerants
• Three levels of sensitivity adjustment

The hilmor Infrared Refrigerant Leak Detector is a hand-held leak detector that uses the infrared detection method. Compared with the traditional leak detector, its sensor has a longer life, higher detection accuracy, greater ease of use, and detects a wider range of refrigerants. The LDIR150 is equipped with a large, easy to read TFT LCD screen.

Battery voltage indicator

The Battery Voltage Indicator shows battery level. 4 bars in the battery icon indicate full battery; one bar indicates low battery.

Sensitivity adjustment

The unit provides three levels of sensitivity adjustment. When the unit is switched on, it is set to the lowest sensitivity position. To change the sensitivity, press the SENS button; The LED screen will display the corresponding sensitivity level: L for Low, M for Medium, and H for High.

Sensor status indicator

The unit automatically diagnoses and indicates the sensor’s status. When switched on, the circuit automatically senses the condition of the sensor, indicating a failed or missing sensor.

If the circuit detects a failed or missing sensor, this image is displayed and the leak detector will stop working.

The unit features two indications – an internal speaker audible alarm, and TFT LCD displays a visual notification. When refrigerant is detected, the detectors show leakage level in bar chart form. Green indicates “no refrigerant detected / no leak”, and Red indicates detection of refrigerant in high concentration.

When the unit is switched on, the audible alarm is activated by default. The audible alarm may be disabled by pressing the MUTE button. Press the MUTE button again to allow audio as well as visual notification. The audio notification may also be heard via headphones plugged into the 3.5mm headphone jack.
