373 Dew Point Mirror - Process Insights

373 Dew Point Mirror - Process Insights

The 373 is a de-facto standard in humidity measurement for over 15 years. Incremental development based on operational experience and customer feedback means that the 373 continues to meet the expectations of hundreds of users in some of the most challenging applications.
Despite its high specification, the 373 is easy to use and simple to maintain. Even early instruments remain serviceable thanks to the use of industry standard component architecture and careful control of software build records.
Recent 373 developments include improved materials of construction to further reduce sorption effects, higher pressure capability based on new mechanical designs, data acquisition software with external generator control, and multichannel thermometer data integration.

Features:

• Wide measuring range -95 to +95 ̊C frost/dew point
• Dual mirror temperature sensors
• Removable mirror module for calibration in liquid
• Heated measuring heads and sampling systems
• High pressures up to 20000 kPa
• Temperature controlled sampling system
• Fast response
• Touch screen full color LCD user interface

473 Dew Point Mirror - MBW

473 Dew Point Mirror - MBW

The 473 is the lowest cost MBW dew point instrument, yet it has high performance and the same user interface as its more expensive siblings. 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. Using both measured variables, the 473 is able to calculate, display and output relative humidity. As an option, the 473 can be specified with a barometric pressure sensor. Two standard measuring heads with 2 m connecting cables are available (lengths up to 10 m can be provided on request).

The SH2 measuring head is supplied with a small sample fan with variable speed to generate a steady gas flow over the dew point mirror. It can also be connected to systems with sampling points tubes using standard 6 mm or 1⁄4” gas fittings. It is very well suited as a transfer standard in humidity chambers and calibration systems.

The RP2 measuring head is designed to be placed directly into environments with existing gas flow. An example would be a RH calibration chamber where a circulation fan is used to mix the air so that its temperature and humidity are uniform.
In combination with the T12 multichannel thermometer, the 473 is particularly well suited to climatic chamber validation projects.

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

573 Dew Point Mirror - Process Insights

The 573 Dew Point Mirror is a high performance 19″ rack format instrument that is very well suited to fixed industrial installations. The 573 is equipped with an integral measurement head, pressure sensor, sample pump and flow meter for continuous precision monitoring of frost/dew point and absolute humidity values across a wide range of applications. Similar in specification to the 973, the 573 adds the capability to measure dew points above the ambient temperature thanks to versions with heated measuring heads and sampling tubes. A special option on the 573H and 573HX variants is an automated steam trap that provides user controlled draining of condensation collected during operation at dew points up to 95 ˚C.

Features:

• Integral frost/dew point measuring head
• Internal sample pump
• Optimal Response Injection System
• ForceFrost™ 
• Ice-Test user calibration verification
• User configurable sampling circuit
• Drop-in replacement for DP3, DP8 and DP30
• Dew points up to +95 ˚C

973 Dew Point Mirror - Process Insights

973 Dew Point Mirror - Process Insights

The Model 973 Dew Point Mirror is a portable Instrument equipped with an integral measuring head for both spot and continuous measurement of frost/dew point and temperature in air and gas. Based on the chilled mirror principle, the 973 provides fundamental, drift free and precise humidity measurement. The 973 has no need for either humidity sensor replacement or calibration adjustment. Unlike sensor-based systems, routine maintenance is conveniently limited to occasional mirror cleaning. Users can self-check instrument calibration stability using the integrated Ice-Test function.

Features:

• Fundamental drift free humidity measurement
• Integral frost/dew point measuring head
• Internal sample pump
• Optimal Response Injection System for fast measurement
• Pressures up to 20 bar
• Intuitive, easy to use LCD touch screen user interface

473-SHX Dew Point Mirror - Process Insights

473-SHX Dew Point Mirror - Process Insights
 

Humidity and temperature reference hygrometer for temperature up to 125 °C.

The SHX measuring head is an evolution of the tried and tested SH measuring head. It is able to operate in test conditions up to 125 °C thanks to the use of optical components, electronics and materials that are able to withstand high temperatures. Our development team tested a range of components over the SHX working range to achieve the best possible performance. By comparison with our state-of-the-art 373 reference hygrometer, we were able to verify that the performance meets or exceeds the specifications.

The key components of the SHX such as the optical module and fan assembly can be easily replaced by the user without the need for system re-calibration.

• Precise and stable chilled mirror dew point mirror technology
• High temperature optical components
• High temperature sample fan
• Cable mounted dew point measuring head
• Barometric pressure measurement option
• Intuitive color touch screen user interface
• Integral calibration stability verification
