The ZFP9 infrared CO₂analyser r uses non-dispersive infrared (NDIR) spectroscopy to measure the concentration of carbon dioxide in a gas. It works by detecting the absorption of specific wavelengths by CO₂ molecules. The ZFP9 infrared CO₂analyser r provides accurate and reliable measurement of CO₂ concentration in agricultural, industrial, laboratory, and HVAC environments.

The ZFP9 non-dispersive infrared (analyser ) gas analyzer is designed to measureCO2 concentrations in the air. Air analysis is performed using a non-dispersive infrared (NDIR) sensor, which enables the ZFP9 to accurately measureCO2 concentrations.
Thanks to its standard alarm functions (high and low limit), it can also be used as a control element.
The measured value is displayed directly on the indicator and sent to the analog output (4 to 20mA) included in the standard model.

Operating principle NDIR
Theanalyser is based on the single-beam NDIR principle, a proven method for measuring gas concentrations. The device uses an infrared source to emit a beam of light through the ambient air containing CO2. A detector then measures the amount of light absorbed by the CO2, allowing for an accurate determination of the concentration.
Extended Measurement Scales
With a measurement range of 0 to 20%, theanalyser offers the flexibility needed for a variety of applications, from residential settings to demanding industrial environments.
Reliability and precision
Exceptional repeatability of ≤ ±1% ensures reliable, consistent measurements. What's more, zero drift is maintained at ≤ ±10% for a period of 6 months, guaranteeing long-term stability of results.
Fast Response Time
The fast response time of ≤ 10 seconds enables real-time monitoring, which is crucial in environments where variations in CO2 levels need to be detected quickly.
Advanced Sampling System
Equipped with an extraction pump and a filter, theanalyser ensures efficient sampling of ambient gas. This guarantees accurate measurements even in environments where the composition of the air may vary.
Adaptability to supply voltage
Available in versions designed for AC supply voltages of 100 V, 115 V, 200 V, or 230 V, theanalyser can be easily integrated into a variety of infrastructure setups.
Compact dimensions and light weight
Measuring 220 (W) x 257 (H) x 85 (D) mm and weighing approximately 3 kg, theanalyser offers a compact and lightweight solution, making it easy to integrate into various spaces and setups.
