MESO-H is a Smart and universal, Isolated 2- wire In-head transmitter for temperature and other measurement applications.
MESO-HX is the Intrinsically Safe version for use in Ex-applications.

MESO-H and MESO-HX are fully HART- compatible, with communication through the HART protocol, directly on the 4-20 mA output loop, by using either a general hand-held HART Communicator or the PC software, MEPR0 2.
MEPRO 2 is a Windows based and user friendly software, which facilitates the access to and use of functions like transmitter configuration, documentation, monitoring and calibration.
