GSH-C2H2 is a pre-calibrated sensor module for the E2639-GSH detector and is used to measure acetylene in the range of 0–100% LEL. 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-LEL(C2H2) sensor is suitable for industrial applications such as monitoring acetylene in workshops, production halls, storage areas or laboratories. The device is designed for reliable and safe gas detection, helping to ensure compliance with safety standards in the given environment.

Acetylene is an industrial gas with a faint ethereal odour, produced from calcium carbide or as a by-product of petroleum processing. Unlike many other flammable gases, it is hazardous even at very low concentrations, and its explosive range is among the widest of all industrial gases in use. Under certain conditions, it can even explode without the presence of air.
The smart sensor offers a major advantage during calibration – the entire process can be carried out separately from the installed detector. While the E2639 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 facilities or directly at the manufacturer, Evikon MCI. A dedicated SSC configurator is used for this purpose, allowing the module to be connected to a computer. Once calibrated, the GSH module simply needs to be plugged back in via the M12 connector – without opening the instrument 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 manufacture.
