Product Details
The KTG141 Explosion - proof Infrared Gas Analyzer is used for the
analysis of inflammable and explosive gases.
Introduction
The KTG141 Explosion - proof Infrared Gas Analyzer adopts imported
non - dispersive infrared sensors and advanced digital processing
technology to achieve continuous, automatic, rapid and online
detection of various gases such as CO, CO₂, CH₄, NH₃ and C₆H₁₄.
Compared with similar products, the most prominent features of this
product are high stability, high reliability and high selectivity.
Application Areas
The KTG141 has a flame - proof explosion - proof structure and can
be widely and safely applied in oil refining, chemical industry,
natural gas and other occasions where there are inflammable and
explosive gases.
Instrument Features
- It adopts imported infrared sensors, which have a long service
life, high sensitivity and fast response speed.
- It is equipped 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.
- The instrument adopts a high - performance embedded integrated
touch - screen TFT true - color display, which can simultaneously
display the measured value, historical curve, range, status and
various parameter setting interfaces. Various instrument parameters
can be configured, calibrated and tested through the full - Chinese
touch - screen menu or remote control. The historical records and
curves can be set according to time.
- It has control contact output, over - limit self - alarm (buzzer),
and the control mode can be set at will. The standard current
output is (4 - 20) mA.
