The CO2 alarm GX-D33 is a CO2 warning device for technical CO2 systems with pressurized cylinders as well as poorly ventilated dry ice storage facilities. The GX-D33 is ideal for the so-called tea kitchens in offices where large CO2 bottles for water bubblers are installed. The alarm thresholds have been set appropriately high to immediately detect technical defects, but not immediately sound the alarm in case of CO2 contaminated bad indoor air from exhaled carbon dioxide. The GX-D33 is simply plugged into a free power outlet in the lower area and is ready for operation after 3 minutes. Its internal infrared sensor will operate maintenance-free for years as long as it never comes into contact with water.

punctual delivery
I received the device in its best packaging and put it into operation. Of course, it is difficult for me to determine whether the trigger level is correct and whether it is reliable for a long time. But that's why I'm happy to accept the high price, so that the device is thoroughly tested by the manufacturer - you shouldn't skimp on warning alarms (/fire extinguishers/...). No one ever wants to have to use it, but everyone wants to be sure that it will work when they need it.
The detector hangs on a socket at knee height, because CO2 is concentrated on the floor and that corresponds to the height at which my child breathes. When the kitchen is ready, it will go into the base cabinet where the bottle for the bubbler is.
