Cost-Effective Humidity & Temperature Reference Hygrometer 

The MBW CALIBRATION™ MODEL 473-SH2™ Dew Point Chilled Mirror Analyzer with a cable mounted measuring head with an integrated sample flow control fan delivers fast, high precision temperature measurement.  It is ideal for use in climatic chambers or humidity generators where it functions as a calibration transfer standard for dew/frost point, relative humidity, and temperature.  The 473-SH2 includes precise measurement of temperature with a 2 x 100 mm platinum resistance thermometer (PRT) that can be connected directly to the SH2 measuring head, or to the MODEL 473 display.  Our MODEL 473-SH2 Dew Point Chilled Mirror Analyzer is a specialized version of the MODEL 473 that is specifically designed for measuring the dew point of corrosive gases, such as hydrogen sulfide (H₂S).

FEATURES 

• Cable mounted dew point mirror
• Sample gas flow fan
• Integrated temperature probe
• User replaceable optical components
• Easy mirror access for cleaning
• Optional barometric pressure measurement

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.
