Wall Mount CH2o Formaldehyde Transmitter 4-20mA Analog Output 0-5ppm Electrochemical Hcho Sensor

Output resolution reaches 0.01ppm, capturing fine formaldehyde concentration changes critical for indoor air quality compliance and early contamination warning in sensitive environments.

Measurement repeatability stays within 2% of signal value, ensuring readings remain consistent across repeated tests without requiring frequent recalibration during continuous monitoring.

Default 0 to 5ppm range suits most indoor and industrial air quality scenarios, with custom range configurations available to match specific application requirements.

Electrochemical sensing supports online formaldehyde tracking, suitable for smart homes, air purifiers, HVAC systems, and industrial facilities requiring constant air quality oversight.

Add-on OLED screen allows direct on-site value readout without external devices, remaining clearly legible even in low-light or nighttime working conditions.

Internal temperature and humidity add-on enables joint 3-parameter detection of formaldehyde, temperature, and humidity within a single wall-mounted housing without extra sensors.

Wide-voltage DC input adapts to diverse on-site power supplies while drawing only 0.12W, supporting low-power continuous operation in battery or solar setups.

Full output flexibility covers PLCs, data loggers, SCADA systems, and custom embedded platforms without requiring additional signal converters or interface modules.

Protective wall-mounted housing withstands demanding industrial and outdoor environments, supporting reliable long-term deployment in petrochemical, chemical, and coating facility settings.

Connects to Renke's free cloud platform, enabling centralized monitoring and management of multiple formaldehyde sensors deployed across different locations from a single dashboard.
