7CH2O-10 Electrochemical Formaldehyde Gas Sensor For Measuring Formaldehyde Concentration

Product Features:

• Low - power Consumption: It adopts a low - power design, which is energy - saving and suitable for long - term operation.
• Small Size: The volume is small, which is convenient for project integration and development, and can be easily installed in various detection equipment.
• High Precision and Stability: With high - precision measurement, the sampling accuracy can reach ≤±2%F.S, and it has strong stability, good consistency and repeatability.
• Multiple Concentration Units: Concentration units such as PPM, VOL, LEL, mg/m³, and μg/m³ are optional, which can meet the needs of different application scenarios and data display requirements.
• Temperature Compensation: It has a full - range temperature compensation and data correction function, which can ensure the measurement accuracy in the temperature range of - 20℃ ~ 50℃.
• Safe and Reliable: The intrinsically safe circuit design meets the safety requirements, and is equipped with anti - interference, short - circuit and reverse - polarity protection functions.
• Fast Response: The response speed is fast, and the T90 response time is ≤90s, which can quickly detect the change of formaldehyde concentration.
• Strong Anti - interference Ability: It is equipped with an industrial - grade EMC module, which can deal with harsh on - site environments and electrical interference.
• Diverse Signal Outputs: There are optional analog voltage signals (0 - 3V, 0.4 - 2V), current signals (4 - 20MA), and digital signals (RS485, TTL), which can be easily connected to industrial control systems such as PLC/DCS, facilitating data acquisition and processing.
• Zero Adjustment Function: It has a built - in zero - point fine - tuning function, which is convenient for calibration and maintenance, and can ensure the long - term accuracy of the sensor.
• No Need for Re - calibration: It is precisely calibrated before leaving the factory, and there is generally no need for re - calibration during use, which reduces the user's use cost and operation difficulty.

Product Uses:

• Indoor Air Quality Monitoring: It is used to detect the formaldehyde content in homes, offices, hotels and other places to ensure a safe and healthy living and working environment.
• Industrial Process Control: It is applied to industrial production workshops, such as wood processing plants, paint factories, etc., to monitor the formaldehyde concentration in the production process, ensure the quality of products, and protect the safety and health of workers.
• Environmental Monitoring: It is used in environmental monitoring stations, meteorological departments, etc., to monitor the formaldehyde concentration in the atmospheric environment, provide data support for environmental protection work, and help understand the overall air quality status.
• Gas Detector and Analyzer Manufacturing: It is provided for gas detector production enterprises and gas analyzer R & D manufacturers as a core detection component to help them develop various types of gas detection equipment.
• Smart Home: It can be integrated into smart home systems, and is linked with other devices through the Internet of Things technology. When the formaldehyde concentration exceeds the standard, it can automatically send out alarms or trigger ventilation equipment to purify the air.
• Fire Emergency Detection: In the scene of fire emergency, it can detect the formaldehyde gas generated by the combustion of some materials, provide relevant information for emergency rescue personnel, and help judge the fire - fighting situation and potential hazards.
