Overview

The HD-XMTA series intelligent digital (display) alarm instruments utilize integrated chips, integrating most of the functions of various regulating instruments in current automatic systems. They also incorporate functional circuits such as CPU, I/O, EPROM, and D/A conversion, complemented by a software system meticulously compiled and repeatedly debugged, which endows the instrument with exceptional superior functions. It is one of the only ultra-small, intelligent, and maintenance-free instruments available in the domestic market.
