Probes for demanding CO2 measurements
CARBOCAP measuring devices from Vaisala are suitable for a wide range of applications, for example for CO2 measurements in ppm (parts per million) or in the percentage range. As CO2 replaces oxygen, it can be harmful to humans in very high concentrations. CO2 is only present as a percentage in closed processes such as fermentation and storage in a controlled atmosphere. Percentage measurements are also typical for life science applications such as CO2 incubation.
GMP251 for measurements in the volume percentage range
The CO2 transmitter is an intelligent standalone probe for measuring the CO2 content. Typical areas of application are horticulture, storage and transportation, greenhouses and mushroom cultivation, leakage monitoring, demand-controlled ventilation in harsh environments as well as bioincubators and cold stores.

Application areas of carbon dioxide measurement
Vaisala CARBOCAP® sensor technology offers solutions for a wide range of applications, with specific benefits varying for each industrial application. The technology is used in products for CO2 measurement in the ppm or percentage range.
Why is CO2 measurement important?
In high concentrations, CO2 can be harmful to health as it displaces oxygen. In closed processes, such as fermentation or in controlled storage environments, CO2 is measured as a percentage. Such measurements are also common in life science applications, such as CO2 incubators.
Typical areas of application
- Ventilation control: In buildings with a high number of people, animal accommodation and greenhouses, the technology helps to control ventilation.
- Safety monitoring: In areas with high CO2 concentrations, reliable CO2 measurement with alarm control enables increased safety.
- Biogas production: Here, CARBOCAP technology contributes to the measurement of several gases, improves methane quality and is characterized by its stability and tolerance to demanding environments.
CARBOCAP technology is particularly popular in environments with demanding conditions as it provides high long-term stability and reliable results.
