KTG120 Hydrogen Analyzer (3U Online Type) for Petrochemical Industry

Introduction

The KTG120 Hydrogen Analyzer is an online detection instrument for the hydrogen content in mixed gases. It is developed by combining imported micro - flow thermal conductivity gas sensors with 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 hydrogen production from ammonia decomposition.

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.
• Electronic Flow Control: With electronic flow control, there is no blockage problem.
• Sensor Protection: It comes with a precision filter, which greatly extends the service life of the sensors.
• User - friendly Interface: It has a fully Chinese man - machine dialogue menu, making the operation intuitive and convenient.
• LCD Display: It has a large - screen 320×240 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 and curves at any time.
• Customizable Control Points: The upper and lower limit control points can be set arbitrarily within the full measurement range.
• Communication Function: It is equipped with a standard RS232 or RS485 communication port, enabling two - way communication with a computer.
