Our Madgetech Process series of data loggers accurately record the output from 4-20mA sensors.

With 16 bit resolution, they are ideal for accurately measuring battery currents, solar cell currents and other current sources. Since they operate with an internal battery (replaceable), ground loop errors can be avoided.

The Madgetech Process101 and Process110 are small, lightweight single channel current loggers that can be placed in-line where needed. The QuadProcess and OctProcess are 4 and 8 channel current loggers respectively. These rugged recorders can be bolted in place and will record data on multiple channels.
