GSH-SO2-2K is a pre-calibrated sensor module for the E2639-GSH detector and is used to measure sulphur dioxide within a range of 0...2000 ppm. It connects via an M12 connector and can be replaced while live without opening the detector housing. The integrated calibration calendar monitors the date of the next calibration, while the calibration itself can be carried out separately from the installed E2639 main unit using the SSC configurator.
The GSH-SO2 sensor is designed for monitoring sulphur dioxide in environments such as wineries and food processing facilities, where SO₂ is used as a preservative, as well as thermal power stations and industrial boiler houses, sulphuric acid production plants, paper mills and pulp mills, refrigeration equipment, and other enclosed spaces where SO₂ may accumulate.

Sulphur dioxide is a colourless gas with a sharp, choking odour that is easily detectable even at low concentrations. It is produced mainly by the combustion of sulphur-containing fossil fuels such as coal and oil, and also during industrial processes, for example in the production of sulphuric acid or metal smelting. Even short-term exposure to sulphur dioxide can cause irritation of the eyes, nose and respiratory tract, while higher concentrations are particularly dangerous for people with respiratory conditions.
The smart sensor offers a major advantage during calibration – the entire process can be carried out separately from the installed detector. While the E2639-GSH main unit remains in operation at the installation site, the GSH sensor module can be removed and calibrated independently – at the distributor’s premises, the integrator’s premises, or directly at the manufacturer Evikon MCI. A dedicated SSC configurator is used for this purpose, through which the module is connected to a computer. Once calibrated, the GSH module simply needs to be plugged back in via the M12 connector – without opening the device housing, without complicated procedures, and without any downtime for the entire installation.

Each sensor package includes the manufacturer’s original calibration certificate in English, confirming the accuracy and correctness of the measurements at the time of leaving the factory.
