PM 175

The PM175 is a compact, multi-function, three-phase AC power meter and power quality analyzer specially designed to meet the requirements of users ranging from electrical panel builders to substation operators. Bright 3-row LED display provides easy local meter readings. The display module is freely detachable and can be located at a distance of up to 1000 meters from the device. Two communication ports allow local and remote automatic meter readings and setup though the supplemental communication or user data acquisition software. (Various communication preferences are made available for remote communications with the meter inclusive of public telephone lines, LAN and the Internet.)
