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.
