The new SERVOPRO MonoExact gas analyzer brings Servomex’s acclaimed TruRef Thermal Conductivity (TCD) technology to ASU operators as a compact, single component analyzer.

Servomex’s TruRef TCD technology offers accurate measurements for argon and nitrogen by eliminating the distorting effects of changing thermal mass and thermal convection experienced by traditional katharometer technologies.

Achieved by co-locating the reference and measure elements under isothermal conditions in the sample gas to eliminate the effects of changing sample conditions, TruRef technology also avoids the measurement inaccuracies inherent in katharometer technologies, which require a sealed reference cell or flowing reference gas.

This means, explains Servomex, that the MonoExact offers ASU operators truly industry-leading measurements for drift accuracy, linearity and repeatability. In addition, cost-of-ownership is optimized by longer calibration intervals and avoiding the requirement for a reference gas.

The single-measurement focus of the MonoExact meets the requirements of ASU operators who prefer to keep their analyzer measurements separate by using independent analyzers, rather than using a single unit multigas analyzer. The compact half-19” rack foot print enables two MonoExact analyzers to be to be installed within a single 19” rack space, maximizing the use of valuable space.

The MonoExact measurement offers stable and robust performance, with control optimized via a full range of communication options that includes 4-20Ma output, Profibus and Modbus communications via RS485, and ethernet connectivity.

Specialty Gas Report understands that an expanded range of TCD gas measurements, to extend the MonoExact’s capabilities, will be released for sale during 2012.
