GSH-N2O is a pre-calibrated sensor module for the E2639-GSH detector and is used to measure nitrous oxide in the range of 0–1000 ppm. It connects via an M12 connector and can be hot-swapped 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-N2O sensor is designed for monitoring nitrous oxide in environments such as healthcare facilities, dental surgeries, operating theatres, chemical laboratories, food processing plants and other enclosed spaces where N₂O may accumulate. The device helps prevent health risks associated with exposure to this gas and contributes to ensuring the safety of both personnel and operations.


Nitrous oxide is a colourless gas with a faintly sweet odour, the presence of which in air cannot be reliably detected by the senses at normal concentrations. In enclosed spaces, it can accumulate to dangerous concentrations and, at higher levels, has a narcotic effect on the central nervous system. Exposure to elevated concentrations of nitrous oxide may cause dizziness, nausea, disorientation or loss of consciousness, and prolonged exposure may result in damage to the nervous system, impaired blood formation due to inhibition of vitamin B₁₂, and adverse effects on reproductive health.
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, integrator’s 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 downtime for the entire installation.

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