973L Model

Portable & Includes Mirror Pre-Cooling 

High Performance Chilled Mirror Hygrometer

High-Performance Hygrometer in a New Design

Our MBW 973L Model Chilled Mirror Dew Point Hygrometer has a completely new design with an optimal Response Injection System for fast measurement.  It is the first transportable MBW to include mirror pre-cooling, so the measurement range is extended to dew/frost points to -76 °C (1 ppmv). As with our instruments with an integral measuring head, the 973L Model includes a 0.1% accuracy pressure sensor so that dew/frost point measurements can always be referred to the actual pressure.

Features and Benefits

  • Fundamental drift free humidity/moisture measurement
  • Integral frost/dew point measuring head
  • Optimal Response Injection System for fast spot checks
  • Integrated Stirling Pre-Cooler
  • Pressures up to 20 bar
  • Intuitive, easy to use LCD touch screen user interface
  • Transport case as standard
  • Optional Internal sample pump
  • Optional high accuracy temperature measurement

    APPLICATIONS

    • Moisture analyzer calibration
    • On-site dew point sensor calibration
    • Compressed air system validation
    • Dryer performance validation
