Strong in design, durable and practical in use
CO₂ is an indicator of indoor air quality and can also be used as an indicator of air hygiene (COVID-19). From schools, wineries, heating and ventilation technology, air conditioning systems to energy management in buildings and greenhouses applications: The compact G 1910 CO₂ portable instruments are real hand charms that make a good impression everywhere.
The GHM GROUP features many practical attributes to make the portable instruments highly suitable for practical use: an easy-to-read display with backlighting as well as the metal belt clip including a neck loop, which significantly increase mobile comfort.
- Compact design and handy format
The attractive design features more comfort and easy operation
- Rechargeable via cell phone cable or use in constant operation
The standard MicroUSB connector makes you independent of special power supplies and allows constant use as well as charging at any power outlet
- Long operating time
The long-lasting battery combined with very low power consumption allows for measurements over a long time span
- Easy battery replacement and calibration
Easily replaceable standard NiMH size AA batteries provide reliable operation of the CO₂ monitor, for greater safety and for comfort
- Dependable signal and warning function
The two adjustable warning/alarm limits alerts with beeps and flashes when the value exceeds 2,000 ppm (factory setting). By pressing any key, the warning signal is suspended for 5 minutes.

„With the support of users, we developed the G1910 portable instruments into practical measuring tools with an unusually wide measuring range for the ubiquitous CO2.“

Strong ideas, practical application
With the handy charging cradle G 1000 Base, the device can be used as a standalone unit or mounted on the wall to save space. Greisinger offers a special service with the download possibility of a free 3D file for the charging cradle. Hence, owners of a 3D printer are able to print the files on their own – those who do not own a 3D-printer can have the tray printed using an appropriate inexpensive printer service.
The free choice of colors comes as an special design aspect.
