• Independent air chamber structure, fast response, good long-term stability.
• Each unit can be switched with each other, automatically track the zero point to prevent drift, and multi-level calibration.
• Standard infrared remote control can be operated without open cover in dangerous occasions, remote control distance of 15 meters, simple and practical.
• It can communicate with the computer, monitor the concentration of the on-site probe in real time through the host computer on the computer, and store, analyze and print the data on the computer.
• Can detect the poisonous and harmful gas, flammable and explosive gas, the concentration of volatile organic gas and in the field display real-time density and standard signal output, signal stability, high sensitivity and precision, etc. The flame-proof connection mode is suitable for all kinds of dangerous sites.
