MP-2 Measurement Platform

An advanced portable meter with unique selection of transient thermal conductivity sensors for a variety of applications, with a focus on primary measurements. 

Best for liquids, solids, pastes and powders
Measurement Platform (MP-2)
Thermal conductivity Measurement Platform – 2 (MP-2) users benefit from the convenience and accuracy gained when using primary testing methods. The MP-2 controller auto-detects the connected sensor and loads corresponding testing parameters. Measurements are easily performed with the smart on-board software and transferred to computer with an included Windows utility program.

Features

measurement platform features
The MP-2 is an advanced meter with unique selection of transient thermal conductivity sensors for a variety of applications, with a focus on primary measurements. The transient thermal conductivity sensors share similar principles of operation. The sensor wire is heated using a constant current source (q). The temperature rise is then recorded by measuring the change in electrical resistance of the wire (THW and EFF) or by a resistance temperature detector device (TLS). For samples of high thermal conductivity, the lower the slope; for samples of low thermal conductivity, the higher the slope.

For convenience, the auto-testing function can be programmed on-board or with the MP-2 Windows utility software. Additional on-board and utility features include the ability to review, save or delete, and export results to Excel. To maximize portability, power can be supplied by battery or USB cable. Informative screen icons keep users informed about power status and testing progress.
