I. Main engine: single and multi-gas detectors
The infrared remote controller can adjust the alarm level, concentration calibration, data storage and other attributes of the alarm conveniently and quickly. Intrinsically safe structure design has the function of over-current and over-voltage protection, and the sensor is effectively protected by our patented technology of sensor life detection and over-concentration protection, which greatly increases the service life of the sensor. The 4+4-bit ultra-high brightness digital tube is used to display the current channel concentration, detection gas and electricity, and three high brightness LED indicators can indicate alarm, communication and adjustment operations respectively. Built-in expansion module can expand digital node output, 4-20MA current output and other output modes. With its own I2C communication interface, it can be seamlessly connected with any I2C slave device to facilitate functional expansion.

Second, FSG- 103T (wireless explosion-proof acousto-optic alarm transmitter)
The infrared remote controller can adjust the alarm level, wireless address, wireless power and other attributes of the alarm conveniently and quickly. This product supports at most three alarm level settings to meet the requirements of various places. Built-in two-digit high-brightness digital tube displays the current gas concentration information. In the alarm state, this product can send out three alarm indication signals: sound, light and wireless. The light alarm adopts high-brightness LED, which has the characteristics of long service life and high luminous intensity. The sound alarm adopts high-decibel adjustable sound alarm device, which can reach 1 10 decibel. The wireless alarm adopts high-power wireless module, which can set the maximum power of wireless transmission to reach the visual distance of 500M m. The wireless receiver adopts RF-G3S produced by our company, which has the functions of digital display and voice alarm, effectively indicating the alarm position and danger degree.

Thirdly, sensors (multi-gas sensors)
Compatibility design is adopted to support various types of sensors such as catalysis, electrochemistry, photoionization and infrared, and high-precision professional sampling circuit and high-performance 12-bit AD single chip microcomputer are adopted to further improve the sampling accuracy. The patented explosion-proof air supply outlet design improves the gas reaction speed and shortens the gas dispersion time while ensuring the gas volume. Built-in flash memory storage space up to 16k supports alarm information and detector parameter storage. The standard I2C serial interface can be connected to any I2C device, and other devices can directly access the flash memory space, thus seamlessly realizing data storage or current gas concentration extraction.
