RS485 Output Wall Mounted CH2O Transmitter

ZONEWU RS485 Formaldehyde (CH₂O) Transmitter

Key Applications & Use Cases

Formaldehyde Control in Chemical/Building Materials Production Workshops

Designed specifically for scenarios like chemical synthesis and wood-based panel/resin production, this device accurately monitors formaldehyde emission concentrations during production. Equipped with a high-precision electrochemical sensor, its 0-5ppm measurement range covers the OSHA-recommended action threshold (0.5ppm), while the 0.01ppm high resolution can capture trace concentration changes. Adopting differential transmission technology and optoelectronic isolation design, it effectively resists interference from workshop motor start-stop and equipment electromagnetic radiation, with a data transmission error rate of less than 0.01%, ensuring production safety and compliance.

Industrial Warehouse/Logistics Environment Monitoring

Tailored for long-distance monitoring needs in large raw material warehouses and finished product storage areas, a single bus supports networking of 32-256 devices without complex wiring. The ultra-long 2000-meter communication distance covers large warehouse spaces; paired with the Modbus-RTU protocol, it seamlessly integrates with warehouse management systems. The -40℃~+80℃ wide temperature operating range and IP protection design enable it to withstand dusty, high-humidity warehouse environments, preventing material deterioration or personnel health risks caused by excessive formaldehyde.

Industrial Waste Gas Treatment Efficiency Monitoring

Targeting the inlet/outlet monitoring needs of formaldehyde waste gas treatment equipment, it provides real-time concentration data feedback. With a fast response time of ≤35s, it accurately captures formaldehyde concentration changes before and after treatment, helping optimize treatment process parameters. It supports direct linkage with PLC and industrial configuration software: when concentrations exceed limits, it automatically triggers the waste gas treatment system to operate at an upgraded level or activates sound-light alarms. This meets industrial environmental emission regulatory requirements while retaining complete data logs for easy traceability.
