The KTG111-W trace oxygen analyzer is applied to the on-line
analysis of oxygen content in the building materials industry
Introduction
The trace oxygen analyzer is a new type of intelligent industrial
on-line analyzer developed by combining the electrochemical
detection principle, imported high-performance electrochemical
sensors, and new microcomputer technology.
Application Areas
On-line analysis of oxygen content in nitrogen production from air
separation, chemical processes, protective gases in
high-temperature sintering furnaces for magnetic materials,
protective gases in the electronics industry, and the glass and
building materials industries.
Instrument Features
- Selects imported fuel cell sensors, featuring long service life,
high accuracy, and fast response.
- Adopts electronic flow control, with no blockage issues. It has a
fully Chinese man-machine dialogue menu, making operations
intuitive and convenient.
- Uses a 128×64 liquid crystal display, which can simultaneously show
parameters such as oxygen content, flow rate, date, time, and the
internal temperature of the instrument.
- Has a timed automatic storage function, allowing users to view
stored data at any time.
- Alarm points can be set arbitrarily within the full measurement
range. It is equipped with a standard RS232 or RS485 communication
port, enabling two-way communication with a computer.
