Yokogawa ZR22G, ZR402G, and ZR202G Integral Oxygen Analyzer ZR202, ZR202G Integrated type Oxygen/Humidity Analyzer

1. Product Description
The EXAxt ZR202 transmitter / detector combines benefits of the ZR402 remote analyzer and the ZR22 detector into an intelligent, rebuildable, low-cost measurement device for in-situ humidity measurement. This smart probe features a local LCD display and infrared push-button operation for local adjustment of the instrument and calibration control. HART communication protocol allows easy configuration of the instrument as well as up to the second information on all process variables and diagnostic tools. The Yokogawa ZR202 smart probe offers customers a lower cost of product ownership by significantly reducing installation costs from tubing, wiring and conduit.

  •     Infra-red switch operation
  •     HART communication for configuration
  •     Integrated automatic calibration available
  •     Integral design can reduce installation costs
  •     Allows replacement of Zirconia cell and heater in the field
  •     Can measure either oxygen concentration or humidity

Yokogawa ZR22G, ZR402G, and ZR202G Integral Oxygen Analyzer ZR202, ZR202G Integrated type Oxygen/Humidity Analyzer

ZR22S/ZR22G Yokogawa Oxgyen Meter is EXAxt series ZR Separate type Zirconia Oxygen/Humidity Analyzer which usually work with connected ZR402G or AV550G converter. It is used or combustion monitoring and control in a wide variety of applications and help industries to make considerable achievements in energy saving such as iron and steel, electric power, oil and petrochemical, ceramics, pulp and paper, food, and textiles, also to various combustion facilities, such as incinerators and small- and medium sized boilers. Combustion monitoring and control using the analyzer also contribute to a lowering of CO2, SOx, and NOx emissions by allowing for more complete combustion, thus preventing global warming and air pollution.

3. ZR22S/ZR22G Yokogawa Oxgyen Meter owns below typical features:

1. The built-in heater assembly of the probe can be replaced on site, reducing maintenance costs
2. The probe uses a long-life, high-reliability Zirconia sensor
3. The probe uses three-reference gas supply methods for compensation in applications
4. Remote maintenance using digital communications(HART) reduces maintenance costs

5. Wide range of wetted part material optional, SUS 316 (JIS), Hastelloy, Inconel
