Model 473-RP2

Probe-Type High Performance Chilled Mirror Analyzer

Our MBW CALIBRATION™ MODEL 473-RP2™ is a probe type Dew Point Chilled Mirror Analyzer and is suitable for test chambers or environments with moving air.  It is particularly well suited for use in relative humidity generators where it functions as a calibration transfer standard for dew/frost point, relative humidity and temperature.  

The MODEL 473 Dew Point Chilled Mirror Analyzer can be used to calibrate the RH generator (e.g. before and after on-site tests) or act as the reference during the calibration of RH probes. The 473-RP2 includes precise measurement of temperature with a 3 x 40mm platinum resistance thermometer (PRT) that can be mounted directly to the RP2 measuring head. Using a cable supplied as standard, the PRT can also be mounted on to instrument under test (IUT) in RH calibration scenarios.  This ensures that the temperature used to calculate RH is correct by minimizing the effects of temperature gradients or self-heating of the IUT.

FEATURES

  • 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.
  • Probe-type design: Features a probe-type design that allows for flexible placement and installation in hard-to-reach or harsh environments. The probe is connected to the main unit by a cable, which can be up to 30 meters long.
  • 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: Can be used to 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.
