Stand alone Refrigerant Gas detector TecnoControl SE237SF-1H

Stand alone Refrigerant detector  SE237SFx-H Tecno Control

The SE137SFx-H series is a gas detector for refrigerant gases (halocarbons) 

with a semiconductor sensor calibrated for different gases and find their best application in centralized alarm systems for industries of refrigerants, laboratories, cylinders warehouses storage, compressors rooms, and environments in general where it is necessary to monitor any leaks of refrigerant gases.

The code of each model identifies the type of gas detected and its full scale.

The instruments comprise of a thermoplastic case in which the electronic circuit and the terminals are mounted.
The enclosure has downward facing cylindrical sensor housing with inside a replaceable “Cartridge Sensor” that
contains the sensitive element with the identification and calibration data, for the specific detected gas.
