ACR :: temperature, Electric Current, pressure, process signals Data Loggers

PowerWatch
Plug-style Voltage Disturbance Recorder
ACR PowerWatch logger records essential power quality events and disturbances. It provides safe, stand alone operation with no wires, alligator clips or other exposed wiring. With the capacity to record up to 4000 events and an optical alarm indicating events occurred, ACR PowerWatch is the easiest way to monitor and record essential voltage disturbance information.
