Always this pressure ...
in the safe and proper handling of gas cylinders. Whether CO2 has escaped through your CO2 gas cylinder, e.g. for the water bubbler or at leaky fittings, you can measure comfortably with our GX-D500P. 

Other areas of application are dry ice processing and storage, occupational safety, food refrigeration e.g. of meat and sausage products, beverage dispensing systems, greenhouses with CO2 fumigation and overall thermally demanding rooms with very hot, cold, humid or dusty air or in ventilation systems with drafts.

The GX-D500P is a carbon dioxide warning device with ppm-accurate measurement and display of CO2 concentration in tenths of a percent, as well as display and storage of many operating parameters on a plain text display. The NDIR infrared sensor with high lifetime is permanently monitored by two µControllers and provides precise results.
The room to be monitored is connected to the device via a silicone hose, and a fan wheel ensures accelerated diffusion of the CO2 to the internal CO2 sensor. At the same time, unfavorable temperatures in the outside hose section adapt to the ambient temperature of the warning device.
2 potential-free change-over relays switch in case of alarm (3%) and in case of technical faults detected by the device itself.
The warning concentrations have been set at 1.5% and 3.0% in accordance with the TRGS for CO2 from beverage dispensing systems, but can also be parameterized alternatively by Elektrotechnik Schabus in the factory at the customer's request.
The application of the GX-D500P is always technical, be it the monitoring of CO2 bottles or the processing of dry ice.
