Yokogawa ZR22G Zirconia Oxygen Humidity Analyzer 4-20mA Output

Yokogawa Single - Channel Zirconia Oxygen & Humidity Analyzer

Product Introduction

This analyzer is composed of a probe and a converter, and it functions as both a Zirconia Oxygen Analyzer and a High - Temperature Humidity Analyzer.​

As a Zirconia Oxygen Analyzer, it is highly suitable for monitoring the oxygen concentration in combustion gases of large or small boilers, various industrial furnaces, and combustion devices. It also plays a role in controlling low - oxygen combustion.​

As a Zirconia High - Temperature Humidity Analyzer (of the separate type), it is used for continuous humidity measurement of hot gases in driers that rely on electrical heaters or hot gas as the heat source. Additionally, it finds application in a range of manufacturing processes involving humidifiers and driers, aiding in humidity measurement and control to enhance productivity in these fields.​

Specific application scenarios include:​

For Zirconia Oxygen Analyzer: Large, medium, or small - sized boilers (used for electric power, heavy oil, gas, coal, etc.) and various industrial furnaces (such as oil/steel heating furnaces, coal kilns, etc.).​

For Zirconia High - Temperature Humidity Analyzer: The coloring process in textile factories, the steam curing process for concrete products, various manufacturing and drying processes of building materials, wood, food, etc., and various manufacturing and humidification processes of food products, etc.

Product Features

The ZR802G converter is equipped with a digital display that shows not only the oxygen concentration but also the cell temperature and cell emf.​

It includes a Human Machine Interface (HMI) with an easy - to - use touch - screen operation, making the operation more convenient.​

It has dual functions, serving as both an oxygen analyzer and a high - temperature humidity analyzer, meeting diverse measurement needs.​

The separate type Zirconia High - Temperature Humidity Analyzers can continuously measure the humidity of hot gases, which is beneficial for improving productivity in relevant application fields.​
