Intelligent Gas Sensor

Intelligent Gas Sensor

Product introduction
4NE/7NE series of Intelligent Gas Sensor Is designed for gas detector manufacturers to launch new intelligent sensor, mainly to solve the problem there are many different kinds of gas detection, calibration of sensor are incompatible each type, production complex, core component replacement limit and so on. Use the intelligent gas sensor of our company need to develop a product, you can quickly response to customer demand for different types of gas detection, and simplify the production process, the need to calibration, reduce the cost of enterprise research and development costs, production, product quality also immediately ascend to the international first-class level.
The sensor is easy to operate, measurement accuracy, reliable operation, and suitable for industrial field or laboratory measurements of different requirements. Sensor has a voltage and a serial port output characteristics at the same time, convenient debugging and use.


Applications
Intelligent gas gas sensor is mainly used in the field of poisonous and harmful gas detection, air pollution monitoring, industrial safety testing, indoor environment testing, various needs gas testing environment, 4NE mainly used for intermittent detection products, such as: gas detector, gas leak detection instrument, experimental analysis and detection field all need only for short periods of time, NE mainly used in on-line continuous inspection field, such as: gas analyzer, gas alarm, so all need 24-hour monitoring of the environment for a long time.

Features of ND Sensor
■The Ann circuit design, can be with electric plug pull operation;
■Professional, original imported, compatible with infrared, electrochemistry, catalysis, semiconductor and other sensors;
■With temperature compensation, the factory precision calibration, when using, no need to calibration;
■Voltage/Current and the serial port output characteristics at the same time, convenient debugging and use;
■The most simplified peripheral circuit, the production is simple and convenient operation.
