Portable Nitrogen Detection and Alarm Instrument

Product Overview：

Overview: The fixed on-line gas detector adopts a high-performance intelligent gas sensor. It is an online detection instrument that can continuously monitor toxic and harmful gases, combustible gases, oxygen, carbon dioxide, and volatile organic compounds VOC and TVOC. The detector uses more than 30 kinds of smart sensors that can be plugged and played, including imported PID photoion sensors, electrochemical gas sensors, oxygen, catalytic combustion sensors, infrared CO2 sensors, and infrared CH4 sensors to adapt to the detection of different industries need.The detector has an overall explosion-proof structure, stable signal, high sensitivity and precision.The detector can realize real-time concentration display on the computer through the gas alarm controller and monitoring management software, and can also transmit real-time data and alarm status to the safety control center through the optional wireless module.It can be widely used in petroleum, petrochemical, metallurgy, environmental protection, gas, fire protection, municipal, pipe gallery, chemical industry, shipbuilding, electric power, process control, sewage treatment, emergency rescue monitoring and other industries.
Parameters: ◆High-performance intelligent gas sensor with a service life of more than 2-3 years;
Parameters: ◆Active pumping type and diffusion type are optional, short response time, 32-bit ultra-low power consumption microprocessor, small detection error and high resolution;
Parameters: ◆Support ppm and mg/3, %VOL and mg/L concentration units can be switched freely;
Parameters: ◆Intelligent temperature and humidity and zero point compensation algorithm, full software automatic calibration function for target points above level 2, to ensure the accuracy of measurement results, and automatically detect the working status of each sensor and components when starting up to ensure the stability of the instrument;
Parameters: ◆High-definition LCD display screen, large and clear backlight can display measurement results under any lighting conditions, friendly user interface with 4-key navigation, showing the humanization and internationalization of the design;
