The CI-PC312 gas analyzer is a high content oxygen detection instrument. The analyzer is based on a microprocessor and uses a sensor based on the principle of magnetic mechanical measurement as the measuring unit to detect the concentration of O2 in gas. It has the characteristics of intelligence, high sensitivity, high accuracy, and good stability. The analyzer has functions such as alarm output, analog signal output, communication, etc. It supports O2 concentration display and is suitable for O2 concentration detection in air separation high-purity oxygen analysis, high-pressure oxygen storage, industrial control, pharmaceutical, nuclear industry, and chemical application fields.
