Principle
The instrument adopts a pump-suction sampling method with a built-in powerful Vacuumpump to extract environmental gases. After the gas enters the instrument, it is detected by the imported electrochemistry oxygen body Sensor, which converts the gas concentration signal into an electrical signal. The microcontroller processes these signals through a 24-bit ADC data collection chip and displays the oxygen concentration value on a 3.5-inch industrial color screen. The instrument supports multiple concentration unit switching and range automatic switching, and can perform multi-level calibrating through software to ensure accurate measurement.
Applications
Industrial environment, special environment
Standards
Explosion-proof marking: ExdII CT6 (intrinsically safe type)
