473 Dew Point cHILLED Mirror Hygrometer

Dew Point Chilled Mirror Analyzer

High Performance 473 Dew Point cHILLED Mirror Hygrometer

Cost-Effective Humidity and Temperature Reference Analyzer

Our MBW CALIBRATION™ MODEL 473™ Dew Point Chilled Mirror Hygrometer Analyzer  is our most cost-effective dew point instrument and performs like our high-end chilled mirror hygrometers. It features cable mounted dew point measuring heads that allow the user to measure directly within the application environment and includes a temperature probe as standard. The MODEL 473 dew point chilled mirror hygrometer is a high-performance instrument that offers several benefits for measuring dew point temperature and other humidity-related parameters.

Features

  • Highly precise chilled mirror dew point technology
  • Cable mounted dew point and temperature measurement
  • Aspirated and direct insertion measuring heads
  • Barometric pressure measurement options
  • Intuitive color touch screen user interface
  • User verifiable calibration

All 473 instruments are delivered as complete measurement sets that include:

  • 473 display 
  • Measuring head
  • Measuring head cable
  • Pt-100 temperature probe and cables
  • Factory calibration certificate*
  • IP65 transport case

In combination with the T12 multichannel thermometer, the 473 is particularly well suited to climatic chamber validation projects.

* For a small additional cost, the factory calibration can be upgraded to ISO17025 accredited calibration

    Key Specifications

    • Frost/dew point range: -30 to +99 ̊C
    • Temperature: -50 to +100 ̊C
    • Temperature with T12: -200 to +250 ̊C

    Typical Applications

    • Climatic chamber validation and calibration
    • Weather station calibration
    • RH generator transfer standard
    • Engine test cells

    BENEFITS

    • High accuracy: Uses the chilled mirror technique to measure dew point temperature, which is considered to be the most accurate method for measuring humidity. The instrument provides high accuracy and repeatability, with a measurement uncertainty of ±0.05°C.
    • Wide measurement range: Can measure dew point temperatures from -100°C to +120°C, making it suitable for a wide range of applications. It can also measure frost point temperatures down to -110°C.
    • Fast response time: Provides fast response times, with a typical response time of 5 minutes for a 90% step change in humidity. This allows for real-time monitoring and control of humidity levels in various applications.
    • User-friendly interface: Features a user-friendly interface with a large, easy-to-read display and intuitive menus. The instrument can be operated with just a few buttons, and it provides on-screen prompts to guide the user through the measurement process.
    • Low maintenance: Designed for easy maintenance, with a simple mirror cleaning process that can be done quickly and easily. The instrument also features a self-diagnostic function that alerts the user to any issues that may require attention.
    • Robust design: Built to withstand harsh environments and can be used in a wide range of applications. It features a rugged, portable design with a protective carrying case, making it easy to transport between locations.
    • Traceability: Is traceable to national standards, providing assurance of the accuracy and reliability of the measurements. The instrument also features a built-in data logging function, allowing for easy record-keeping and documentation of the measurements.
    • Versatility: Is a versatile instrument that can measure various humidity-related parameters, including dew point, frost point, and absolute humidity. It can also be configured for different measurement units, such as Celsius, Fahrenheit, and parts per million by volume.
    • Connectivity: Can be connected to a computer or network via a USB or Ethernet port, allowing for remote monitoring and control of the instrument. The instrument also supports various communication protocols, such as Modbus and SCPI, for easy integration with other systems.
