Continuous Dew Point Measurement You Can Trust.

Industrial processes often require more than a portable humidity measurement. They need a permanently installed reference-quality instrument capable of continuously monitoring changing moisture conditions.

The MBW CALIBRATION™ Model 573™ Industrial Chilled Mirror Hygrometer provides direct, high-precision measurement of dew point, frost point and absolute humidity for industrial processes, test systems, climatic chambers and calibration applications.  Available in three configurations, the Model 573 provides measurement ranges extending from −60°C frost point to +95°C dew point, with heated versions designed specifically for measuring dew points above ambient temperature.

FEATURES

Some of the key features and benefits of the MODEL 573 Dew Point Chilled Mirror Analyzer include:

• High accuracy: Capable of measuring dew point temperatures as low as -100°C (-148°F) with an accuracy of ±0.1°C (±0.18°F). This makes it suitable for use in a wide range of applications where precise control of humidity levels is critical.
• Fast response time:  Has a fast response time, allowing it to quickly detect changes in dew point temperature and respond accordingly. This is especially important in applications where rapid changes in humidity levels can occur, such as in industrial processes and environmental monitoring.
• User-friendly interface: Features a large, easy-to-read display and intuitive menu navigation, making it easy to operate and configure. It also has a variety of output options, including analog and digital signals, making it easy to integrate into existing systems or data loggers.
• Robust design: Built to withstand harsh industrial environments, with a rugged aluminum housing and a heated mirror assembly that prevents frost and condensation from forming on the mirror surface.
• Versatility: Can be used in a wide range of applications and industries, including environmental monitoring, industrial processes, HVAC systems, and more. It is also available in a variety of configurations to suit specific application requirements, such as the addition of a built-in sample conditioner or a range of different power options.

What Is the MBW Model 573?

The MBW Model 573 is a fixed-installation industrial chilled mirror hygrometer used for continuous, high-accuracy measurement of dew point, frost point and humidity in gases. The instrument uses the chilled mirror condensation principle to directly determine the temperature at which water vapor condenses.

The Model 573 combines an integral measuring head, pressure sensor, internal sample pump and flow meter in a 19-inch rack-format instrument designed for continuous operation.  Unlike the portable Model 973, the 573 is optimized for permanent installations and offers heated configurations that allow measurement of dew points above ambient temperature.

Features and Benefits

Heated Hoses

When measuring dew point above ambient temperature, condensation will form in sample lines where the tube/hose temperature is below the dew point temperature. Heated sample hoses solve this problem by maintaining the tube temperature at a higher temperature. MBW supply heated sample hoses in a range of lengths and fittings to suit most applications.

The heated hose only provides sample path heating upto the inlet connection of the instrument. To avoid condensation inside the instrument, its internal sample path and measuring head must also be heated.
