  • Warm-up time: approximately 6 seconds;
  • Reset time: 2 to 10 seconds;
  • Power Supply: 6V DC, 4AAA Batteries

Detection Range
The CLD-100 may also be used to detect leaks in other systems and storage/recovery containers. It will respond to all halogenated (including Chlorine and Fluorine) refrigerants. This includes but not limited to:
CFCs e.g.R12,R11,R500,R503 etc.
HCFCs e.g.R22,R123,R124,R502 etc.
HFCs e.g.R134a,R404a,R125 etc.
Blends such as AZ-50, HP62, MP39 etc.
Detect Ethylene Oxide gas leaks in hospital sterilizing equipment (it will detect the halogenated carrier gas).
Detect SF-6 in high voltage circuit breakers.
Detect most gases that contain chlorine, Fluorine and Bromine(halogen gases).
Detect cleaning agents used in dry cleaning applications such as perchloroethylene.
Detect halogen gases in the fire-extinguishing system.

Battery Indicator
The forepart light of the panel indicates the leak and the battery voltage.
GREEN- Battery voltage is normal, sufficient for proper operation.
ORANGE- Low Battery voltage, and it is approaching the lower threshold for operation.

Operation Instruction:
- Switch on the detector and buzzer will beep discontinuously.
- Verify the battery and voltage level by observing the power indicator.
- Adjust appropriate sensitivity, or adjust the sensitivity at any time during operation. This adjustment will not interrupt detection.
- To detect a leak when the detector is switched on for 6S.
- When a refrigerant leak is detected, the buzzer will turn to a “siren” sound.
- Verify the place where siren sounds and detect continuously until the leak is located.

Operation Tips
- Adjust to higher sensitivity when a leak can't be found. Adjust to lower sensitivity when the detector runs unstably.
- When the buzzer alarms for leak, if the sensing tip remained at the part being detected long enough, the circuit will equalize it.
- In windy areas, even a large leak is difficult to be found. Under this condition, it is better to shield the potential leak area.
- Be aware that the detector may alarm if the sensing tip contacts with moisture and/or solvents. Therefore, avoid contact with these during leak checking.
