Model CRO-310 -Online Zirconia Oxygen Analyzer

The instrument is divided into two types: constant temperature type and floating temperature type. Among them, the constant temperature type is suitable for applications below 600 °C, and the floating temperature type of corundum ceramic structure is used for high temperature occasions when the measured gas temperature is 600-1200 °C. It is used in the analysis of oxygen content in inert gas (nitrogen, argon, etc.) in petrochemical, metallurgical electronics, fertilizer, glass building materials, oxygen production, etc. It is an ideal equipment for product quality, process control and product testing.

• Imported original detector, stable performance, long life and fast response
• Large screen dot matrix LCD display, Chinese man-machine dialogue menu, easy to operate
• Adopting floating temperature measurement scheme, greatly improving the reliability of the instrument
• The detector adopts all-ceramic structure, which is especially suitable for on-line detection of oxygen under high temperature (600~1200 °C) gas.
• With automatic timing storage, you can view stored data at any time.
• Measured value upper and lower limit alarm output is set arbitrarily
• Online calibration with available calibration gas
• With standard 4~20mA linear analog signal output
• Communication RS232 interface can be connected to the computer for real-time data transmission

• Air separation, automatic analysis of oxygen content in chemical processes
• Semiconductor, magnetic material production
• Float glass, cement building materials industry
• Automatic analysis of oxygen content in various industrial furnaces and heat treatment processes
• Electronic components, biopharmaceuticals and other scientific research

The oxygen probe should be installed in a representative flue. The optimal temperature of the thermostat is 300-400 °C. The thermostatic oxygen probe is sealed with the flue and asbestos pad between the flue. It is installed in a horizontal plug-in type. The system is divided into two types: “horizontal plug-in” and “vertical plug-in”. The temperature should be “vertical plug-in” installation in the high temperature range.

Precautions:

• The order of flammable gas in the gas sample to be tested should be lower than the order of oxygen content, otherwise it will affect the accuracy of oxygen measurement.
• When the instrument is used for negative pressure gas sample analysis, the sampling pump should be configured.
