Overview

The HD-XMTA series intelligent digital (display) alarm meters utilize integrated chips, integrating most 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 that is meticulously designed and repeatedly debugged to draw on the strengths of various sources. This results in the meters having exceptional superior functions. They are among the only ultra-small, intelligent, and maintenance-free meters available domestically.
