KTG123 Hydrogen Analyzer (Online Type) for Petrochemical Industry
Introduction
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.
Application Areas
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.
Instrument Features
- 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.
