The core technology of GADE-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, GADE -300 is particularly sensitive for all regrigerant, and could successfully eliminate false signals. The sensor will neither be damaged by the big doses of refrigerant nor be reduced the sensitivity along with the usage time.
