KTG114-W explosion-proof oxygen analyzer

Introduction

The KTG114-W explosion-proof oxygen analyzer is an explosion-proof (flameproof) on-line oxygen detection instrument. It is developed by using sensors with different principles according to different measurement ranges and the latest microcomputer processing technology.

Application Areas

It is used for on-line detection of oxygen content in hazardous places such as hydrogen production and chemical processes, where there are explosive gases or combustibles.

Instrument Features

• Adopts high-performance sensors, featuring long service life, high sensitivity, and fast response speed.
• Adopts a flameproof design.
• Has a fully Chinese man-machine dialogue menu, and the infrared remote control operation is intuitive and convenient.
• Equipped with a 128×64 dot-matrix liquid crystal display, which can simultaneously display parameters such as hydrogen content, date, time, and the internal temperature of the instrument.
• Has a timed automatic storage function, allowing users to view stored data at any time. The upper and lower limit control points can be set arbitrarily within the full measurement range.
• Alarm points can be set arbitrarily within the full measurement range.
