Ac Smoke Detectors
-
Product Highlights- Hvac tools : it has the function of power-on reset and automatic follow-up, which can ignore the concentration level of halogen gas in the environment.
- 134a refrigerant: when the leaked gas is found, the warning sound will become more rapid, and the more leakage, the more rapid the warning sound. at the same time, the indicator light flashes quickly.
- R22 refrigerant: power-on reset: after the instrument is turned on, it can automatically adjust the circuit within 6s to ignore the existing probe.
- Refrigerant ac : sensitivity adjustment: this product has the function of stepless adjustment of sensitivity, which can be adjusted at any time during detection.
- Refrigerant gas detector: auto-following circuit: when the instrument is in the detection state, the automatic circuit will follow the halogen in the environment. changes in the concentration of the element gas to prevent false alarms.

Product Highlights
- Hvac tools clearance-- it has the function of power-on reset and automatic follow-up, which can ignore the concentration level of halogen gas in the environment.
- Refrigerant gas detector-- when the refrigerant concentration level is reached, it enters the detection state. if the user turns on the look for sources of higher concentrations of leaks. the instrument can also be turned on in clean air to adjust to maximum sensitivity, at which point leaks above the zero concentration level can be detected.
- Tif refrigerant leak detector-- it has the function of power- on reset and automatic follow- up, which can ignore the concentration level of halogen gas in the environment.
- R410a refrigerant-- sensitivity adjustment: this product has the function of stepless adjustment of sensitivity, which can be adjusted at any time during detection.
- Ac refrigerant-- auto-following circuit: when the instrument is in the detection state, the automatic circuit will follow the halogen in the environment. changes in the concentration of the element gas to prevent false alarms.
