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.
