KTG140 Infrared Trace Gas Analyzer (Standard 3U Online Type) for the Chemical Industry

Introduction

The KTG140 Infrared Gas Analyzer uses imported semiconductor infrared sensors and advanced digital processing technology to achieve continuous, automatic, rapid and online detection of various gases such as NH3, CH4, CO, CO2, etc. Compared with similar products, the most prominent features of this product are high stability, high reliability and high selectivity.

Application Areas

This analyzer can be used in power plants, metallurgy, cement, fertilizer, chemical industry, environmental protection, scientific research, and other fields.

Instrument Characteristics

• It adopts imported infrared sensors, which have a long service life, high sensitivity, and a fast response speed.
• It uses electronic flow control, with no clogging phenomenon.
• It comes with a precision filter, which greatly prolongs the service life of the sensor.
• It has a full - Chinese man - machine dialogue menu, which is intuitive and convenient to operate.
• It has a large - screen 320×240 dot - matrix LCD liquid - crystal display, which can simultaneously display parameters such as the content of the gas being measured, flow rate, date, time, and the internal temperature of the instrument.
• It has a timing automatic storage function, which allows users to view the stored data and curves at any time.
• The upper and lower limit control points can be arbitrarily set within the full range.
• It is equipped with standard RS232 or RS485 communication ports, which can achieve two - way communication with a computer.
