Sensors
The MP-2 is an economical meter with a unique selection of transient thermal conductivity sensors for a variety of applications, with a focus on primary measurements.
The controller auto-detects the connected sensor and loads corresponding testing parameters. Measurements are easily performed with the smart on-board software and can be transferred to a computer with the included data utility program.
For convenience, the auto-testing function can be setup directly on the controller or on a computer. Additional 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 showcase power status and testing progress.
