Refrigerant leak detectors

The core technology of SLD-300 refrigerant leak detector lies in the sensitivity of nano-materials to the refrigerant. It contains a nano-materialed semiconductor sensor to detect the halogen refrigerant.

Due to the adoption of high accurate and sensitive material of sensor, SLD-300 is particularly sensitive to all refrigerants, and could successfully eliminate false signals. In addition, there is no the problem of instability which usually happened in the negative corona sensor. The sensor will neither be damaged by the big doses of refrigerant nor be reduced the sensitivity along with the usage time.
