BS03 Multi Gas Detector To Detect Natural Gas

Detailed Product Description

Fixed Gas Detector Description
BS03 is a fixed point gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LED screen and LED lights and can be connected to the control panel with a standard 4-20mA analog output.

It is applicable to explosion-proof places: Steelworks, Petrochemical plants, Shipyards, Watertreatment plants, Mines, Power plants, Food industry etc.

Fixed Gas Detector Key Features

• Interchangeable smart sensor module
• Intrinsically safe
• Built-in sampling pump (optional)
• Visual, audible and vibration alarm
• Adjustable alarm levels and span calibration values
• Password management
• Self-test after power on
• Self-diagnostic and self-correction function
• Real-time clock

PID photoionization sensor
1. Principle: Use high-energy ultraviolet light to ionize organic gas, then amplify the current formed by the charged ions on the plate for measurement, and the magnitude of the current reflects the concentration of the gas.
2. Advantages: High sensitivity, can measure ppb level VOC, fast response, fast response time, can measure most VOC.
3. Disadvantages: The sensor cost is very high.
4. Use: Mainly used to detect volatile gases.
