KTG123 Online Hydrogen Analyzer for Petrochemical Industry with (0.00 - 99.99)% Detection Range and Fast Response Time ≤15 seconds

The KTG123 Hydrogen Analyzer is an online detection instrument for the hydrogen content in mixed gases. It is developed by our company through the combination of imported micro-flow thermal conductivity gas sensors and the latest microcomputer processing technology.

It is used for the non-explosion-proof online analysis of the hydrogen content in mixed gases in industries such as petrochemical, metallurgy, power, and air separation, or for the non-explosion-proof online analysis of the hydrogen content in the process of hydrogen production from ammonia decomposition.

• High-performance micro-flow thermal conductivity sensors are adopted, featuring a long service life, high sensitivity, and fast response speed.
• Electronic flow control is applied, eliminating the problem of blockage.
• It is equipped with a precision filter, which greatly extends the service life of the sensors.
• It has a fully Chinese man-machine dialogue menu, making the operation intuitive and convenient.
• With a 128×64 dot-matrix LCD display, it can simultaneously show parameters such as hydrogen content, flow rate, date, time, and the internal temperature of the instrument.
• It has an automatic timed storage function, allowing users to view the stored data at any time.
• The upper and lower limit control points can be set arbitrarily within the full measurement range.
• The alarm points can be set arbitrarily within the full measurement range.
• It is equipped with a standard RS232 or RS485 communication port, enabling two-way communication with a computer.
