Measuring CO2 concentration
Fields of application
The infrared CO2 analyser ZFP9 allows precise and reliable measurement of CO2 concentration in controlled horticulture - Greenhouses, Building Ventilation Systems and Controlled Atmosphere Storage Facilities.
Features
The ZFP9 is a non-dispersive infrared analyser which measures the concentration of CO2 in the air, indicates the result and simultaneously emits an analog signal. Thanks to its standard alarm functions (high and low limit), it can also be used as a control element. This device can be used to measure CO2 concentration in greenhouses, building ventilation systems, storage facilities (controlled atmosphere), etc.
