Benzene sensor module RS485 incorporates high precision electrochemical sensors and uses proprietary circuits to output gas concentration signals into digital signals. The sensor is equipped with high precision amplification, noise removal processing and temperature compensation processing. At the same time, each sensor has been calibrated by standard gas before leaving the factory, so as to ensure that customers can directly output usable and accurate gas concentration information from the sensor module. With small size, easy installation, safety design, high sensitivity, factory has been calibrated and so on.

1. The harm of benzene?
The main harm of benzene to the human body is the damage to the nervous system and hematopoietic system. Benzene has lipophilic properties, can be inhaled through the respiratory tract in the form of vapor into the human body, after entering the human body causes acute poisoning. It can cover the surface of nerve cells, inhibit biological oxidation, affect the transmission of neurotransmitters, and anesthetize the central nervous system. After anesthesia, patients may experience dizziness, headache, fatigue, tinnitus, unsteady gait and hallucinations, and patients with severe mental disorders may experience coma, muscle spasms, pupil dilation and respiratory paralysis.
2. Why use benzene gas detector?
Benzene gas detector, mainly used for the accurate detection and alarm of benzene gas concentration in the air, the product is the original imported sensor, more reliable and stable than the general detector, high precision, high signal noise and resolution. High precision information collection and processing can be realized through software and hardware technology. With zero stability, zero long-term maintenance free function.
