Effect of AN-002 Ventilation Humidity on NDIR LARK-1 CH4 Reading 17-07-12

The specifications of NDIR gas sensors generally give the range of humidity, defined as relative humidity% RH, which means that the range of humidity can be determined. Ensure the humidity range of NDIR sensor working normally. High humidity does not damage the sensor without producing condensate. But it will cause the reading error of the sensor. In the case of methane, for example, the reading will generally be higher when the humidity is high. To study ventilation humidity The influence of degree on the reading of NDIR LARK-1 CH4 sensor. We use LARK-1 CH4 sensor to access different humidity standards. The humidity experiment of the gas was carried out, and the experimental data were analyzed and summarized.

AN-001Z LARK-1 Sensor Communication Protocol EN 21-03-12

The LARK-1 series sensors manufactured by our company provide a set of commands for external devices through RS232 serial communication interface. Standby operation: sensor connection and discovery, information query, data acquisition, ZERO and SPAN calibration functions. Customer availability According to the communication protocol described in this application note, sensors are operated by external devices.

Long-acting ammonia gas sensor

Nowadays, the ammonia sensors represented by Sensoric and embrapor are all water-based, and their detection principle is consumptive. When the active substances in the sensor are exhausted, the lifetime of the sensor is reached.

The special electrochemical sensor 3CO-10000 for flue gas analyzer

At ordinary times, people pay great attention to the air pollution index, among which several indicators are very important: PM10, PM2.5, SO2, NO_x, O_3, CO. These pollutants are mainly discharged from fixed sources, that is to say, after burning fossil energy in boilers and kilns, they are discharged through chimneys. Nowadays, particulate matter is basically detected by optical method, and gas detection is divided into optical and electrochemical methods.

Vinyl chloride sensor

Vinyl chloride gas is an important product and raw material in chemical industry. In this paper, the market situation, physical and chemical properties, production and preparation methods of vinyl chloride are briefly introduced. Then, the performance of dense electrochemical vinyl chloride sensor is emphatically introduced for the selection of gas instrument manufacturers.

Ozone and Ozone Sensor

Ozone (O 3) gas is not common in our life, but it is closely related to our daily life, especially sewage treatment and domestic water. It can be said that O 3 is the "behind-the-scenes hero" of modern human life. In this paper, the physical and chemical properties, commercial uses, production methods and detection methods of O3 are briefly introduced. Then, the electrochemical O3 sensor newly released by Shengmi Science and Technology is introduced in detail, which can be used by gas instrument manufacturers.
