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.
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.
