Wide range of applications including air detection, agricultural planting, production storage, and material processing. Core infrared sensor delivers 1 ppm resolution with 403%ppm measurement accuracy, providing clearer and more accurate readings. Temperature and humidity measurement supports industrial temperature monitoring; includes safety protection, dustproof design, 1.5 m drop resistance, and waterproof construction. Fast measurement with realtime refresh every 2 seconds; supports upper and lower limit measurements, with data retention and overstandard alarm functions. Use scenarios Air detection in factories, laboratories, and storage facilities to monitor environmental conditions and alert on deviations. Agricultural planting and greenhouse environments requiring reliable temperature and humidity monitoring for plant growth. Production storage and material processing environments where fast readings, data history, and overstandard alarms help maintain safety and quality.
