Model 973E 

Cost-Effective Chilled Mirror Hygrometer

Make Drift-Free Humidity Measurements Easily

Our MBW CALIBRATION™ Model 973E™ Dew Point Chilled Mirror Analyzer is a “value engineered version” of the 973 series. It does not compromise on quality and performance, so still includes pressure measurement as a standard feature, can operate up to 10 bar and features ORIS to maintain fast response in spot check applications.

The MODEL 973E Dew Point Chilled Mirror Analyzer is a portable, handheld instrument designed for the measurement of trace moisture in gases. It uses the chilled mirror principle, which involves cooling a surface until dew or frost forms, and then measuring the temperature at which this occurs to determine the moisture content of the gas.

FEATURES

Some key features and benefits of the MODEL 973E Dew Point Chilled Mirror Analyzer include:

  • Portable design: Is lightweight and portable, making it easy to use in the field or on-site.
  • Fast response time: Has a fast response time of less than 5 minutes, allowing for quick and accurate measurements.
  • High accuracy: The chilled mirror principle provides highly accurate measurements, with a measurement range of -100°C to +30°C dew point.
  • User-friendly interface: The analyzer has a user-friendly interface with a large, easy-to-read LCD display, making it simple to operate and read measurements.
  • Low maintenance: The chilled mirror sensor has no consumable parts and requires minimal maintenance, reducing downtime and costs.
  • Wide range of applications: Can be used to measure trace moisture levels in a wide range of gases, including nitrogen, oxygen, hydrogen, and compressed air.

INDUSTRIES

Some of the industries and applications that use the MODEL 973E Dew Point Chilled Mirror Analyzer include:

  • Power generation: The analyzer is used to monitor trace moisture levels in gases used in power generation, such as hydrogen and nitrogen.
  • Semiconductor manufacturing: The analyzer is used to monitor trace moisture levels in high purity gases used in semiconductor manufacturing, such as nitrogen and argon.
  • Petrochemical production: The analyzer is used to monitor trace moisture levels in gases used in petrochemical production, such as ethylene and propylene.
  • Food and beverage production: The analyzer is used to monitor trace moisture levels in compressed air used in food and beverage production, to ensure product safety and quality.
