GSH-NO2-20 is a pre-calibrated sensor module for the E2639-GSH detector and is used to measure nitrogen dioxide within the range of 0–20 ppm. It connects via an M12 connector and can be replaced during operation 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-NO2 sensor is designed for monitoring nitrogen dioxide in environments such as industrial facilities, chemical and analytical laboratories, exhaust and combustion stations, welding workplaces, printing works, and other enclosed spaces where NO2 may accumulate. The device helps prevent health risks associated with exposure to this highly toxic gas and contributes to ensuring the safety of both personnel and operations.
Nitrogen dioxide is a reddish-brown toxic gas with a characteristic pungent odour. Its presence in the air can be recognised by smell at higher concentrations, but reliable detection is not possible without a measuring instrument. In enclosed spaces, it can accumulate to dangerous concentrations and, due to its high reactivity, it aggressively attacks the respiratory tract even at relatively low levels. Exposure to higher concentrations of nitrogen dioxide may cause irritation of the mucous membranes, coughing, shortness of breath or headaches, and prolonged exposure may result in serious lung damage, chemical pneumonitis and adverse effects on the cardiovascular 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 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 manufacture.
