High Quality NDIR Formaldehyde (CH2O) Gas Analyzer 0-50ppm RS485 Output for Indoor air Quality Monitoring

Product Introduction:
This formaldehyde temperature and humidity transmitter (RS485 type) is an industrial grade online monitoring device that integrates high-precision electrochemical sensing, wide voltage power supply, and standard ModBus RTU communication. The product is designed with the core concept of "precision, stability, and durability" and is specifically designed for smart homes, air purifiers, air conditioning systems, and long-term formaldehyde concentration tracking scenarios. It can meet the needs of continuous online monitoring 24/7.
 
Core advantages:

• Excellent measurement performance: formaldehyde range from 0 to 5ppm, resolution up to 0.01ppm, repeatability ≤ 2%, accuracy up to ± 5% FS (@ 1ppm, 25 ℃, 50% RH), synchronous output of temperature (-40~+80 ℃) and humidity (0~100% RH), temperature and humidity accuracy of ± 0.5 ℃ and ± 3% RH respectively, fully covering environmental monitoring elements.
• Flexible and reliable communication: Standard RS485 interface, supporting ModBus RTU protocol, customizable address and baud rate (2400~115200 bps), with a maximum transmission distance of 2000 meters, facilitating network integration.
• Durable and sturdy design: 10~30V DC wide voltage supply, with a power consumption of only 0.12W; waterproof wall mounted casing, suitable for harsh industrial environments; Optional high-quality OLED display screen, with clear and readable nighttime data.
• Intelligent calibration and maintenance: Provide independent calibration registers for temperature, humidity, and formaldehyde, facilitating on-site zero adjustment; Sensor stability ≤ 7% signal value/year, working life ≥ 24 months, preheating only takes 5 minutes, response time ≤ 35 seconds.
