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.
