Formaldehyde (CH2O) Sensor Module
Air quality sensor module for Greenhouse gas monitoring
Oizom offers various Formaldehyde (CH2O) sensor modules to monitor different levels of CH2O, depending on the need. The Formaldehyde sensor module can accurately measure low concentrations of CH2O at the ppb/ppm level in the ambient air. The sensor module design is capable of monitoring formaldehyde emissions from point sources in real-time.
By incorporating low-noise components into its design, the sensor achieves exceptional stability and accuracy in detecting formaldehyde, even at low concentrations. This advanced technology delivers precise measurements, making it an ideal tool for monitoring indoor and outdoor air quality.
The formaldehyde sensor module works on an electrochemical principle. Electrochemical sensors are very sensitive to the presence of CH2O and also provide a stable response to transient relative humidity changes. Hence, they are perfect for indicative real-time air quality monitoring for outdoor applications.
The Formaldehyde sensor (CH2O) is calibrated using standard calibration gases and tools. The calibration is done according to the guidelines of the USEPA (40 CFR Part 53) and EU (2008/50/EC) for equivalent method instruments.
The CH2O sensor module is integrated into odor and air quality monitoring systems like AQBot and Odosense. Therefore, this module is ideal for applications like hospitals, medical facilities, Industries, manufacturing of wood products such as furniture, resin, fertilizers, pesticides, and oil refining.
Oizom offers multiple CH2O sensor module options:
OZCH2O_1
Measurement Range: 0-10 ppm
Minimum detection limit: 0.05 ppm
Sensor Life: 2 years
Working Principle: Electrochemical sensing
Drift: < 2% / Month
OZCH2O_2
Measurement Range: 0-50 ppm
Minimum detection limit: 0.1 ppm
Sensor Life: 2 years
Working Principle: Electrochemical sensing
Drift: < 2% / Month
The Formaldehyde sensor module working on the electrochemical principle is operated based on the diffusion of CH2O gas into the sensor which results in the production of an electrical signal proportional to the CH2O concentration. It allows accurate and reliable measurement of even low concentrations of Formaldehyde, which is essential in CH2O monitoring in the ambient air.
