The KTG112 - G Oxygen Purity Analyzer for On - line Detection and Analysis of Oxygen Content in Medical and Health Fields

Product Description

The KTG112 - G Oxygen Purity Analyzer is a new - type intelligent industrial on - line analyzer developed by our company by combining imported limiting - current sensors with new microcomputer technology.

Application Areas

It is used for the on - line detection and analysis of oxygen content in industries such as air separation for oxygen production, medical and health, petrochemical, metallurgy, electronics and power, as well as home oxygen bars.

Instrument Features

• Integrated Design: It has an integrated design with a small volume, light weight, simple structure, and reasonable layout.
• High - Quality Sensor: It is equipped with imported limiting - current sensors, which feature a long service life, high accuracy, etc.
• Sensor Protection: It comes with a precision filter, which greatly extends the service life of the sensors.
• User - friendly Interface: It has a fully Chinese man - machine dialogue menu, making the operation intuitive and convenient.
• LCD Display: It uses a 128×64 dot - matrix LCD to simultaneously display parameters such as oxygen content, date, time, and the internal temperature of the instrument.
• Data Storage: It has an automatic timed storage function, allowing users to view the stored data at any time.
• Customizable Control Points: The upper and lower limit control points can be set arbitrarily within the full measurement range.
• Customizable Alarm Points: The alarm points can be set arbitrarily within the full measurement range.
• Communication Function: It is equipped with a standard RS232 or RS485 communication port, enabling two - way communication with a computer.
