GSH-EtO-100 is a pre-calibrated sensor module for the E2639-GSH detector and is used to measure ethylene oxide in the range of 0...100 ppm. It connects via an M12 connector and can be hot-swapped without opening the detector housing. An 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-EtO sensor is designed for monitoring ethylene oxide in environments such as sterilisation facilities, hospitals, pharmaceutical plants, chemical stores, and other enclosed spaces where C₂H₄O may accumulate. The device helps prevent health risks associated with exposure to this gas and contributes to the safety of both personnel and operations.


Ethylene oxide is a colourless gas with a sweet, ether-like odour which is highly flammable and explosive at room temperature. It is produced primarily by the industrial synthesis of ethylene with oxygen and is used as an intermediate in the manufacture of ethylene glycol, plastics and detergents, as well as a sterilising agent in healthcare. Even short-term exposure to ethylene oxide may cause irritation of the eyes and respiratory tract, headaches or nausea, while long-term exposure is associated with an increased risk of cancer and damage to the nervous system.
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 facility, or directly at the manufacturer Evikon MCI. This is done using the dedicated SSC configurator, 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 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 manufacture.
