KTG121 Hydrogen Analyzer (Explosion - proof Type) for Explosion -
proof Online Analysis of Hydrogen Content in Metallurgy
Introduction
The KTG121 Hydrogen Analyzer is an explosion - proof online
detection instrument for the hydrogen content in mixed gases. It is
developed by our company by combining imported micro - flow thermal
conductivity gas sensors with the latest microcomputer processing
technology.
Application Areas
It is used for the explosion - proof online analysis of the
hydrogen content in mixed gases in industries such as
petrochemical, metallurgy, power, and air separation.
Instrument Features
- High - performance Sensor: It uses high - performance micro - flow
thermal conductivity sensors, which have a long service life, high
sensitivity, and fast response speed.
- Explosion - proof Design: It adopts an explosion - proof design.
- User - friendly Interface: It has a fully Chinese man - machine
dialogue menu, making the operation intuitive and convenient.
- LCD Display: It uses a 128×64 dot - matrix LCD, which can
simultaneously display parameters such as hydrogen content, flow
rate, date, time, and the internal temperature of the instrument.
- Data Storage: It has an automatic timed storage function, allowing
users to view the stored data at any time.
- Customizable Control Points: The upper and lower limit control
points can be set arbitrarily within the full measurement range.
- Customizable Alarm Points: The alarm points can be set arbitrarily
within the full measurement range.
