The Process101A is a compact data logger that measures and records low-level DC currents. Available in 3 measurement ranges (30 mA, ±160 mA and ±3 A), the Process101A offers a 10-year battery life, ideal for long-term deployments.

The Process101A features a 4 Hz reading rate and storage capacity of 2,095,104 readings. Equipped with multiple start/stop modes, the Process101A can be programmed to start up to 18 months in advance and has user-specified high/low alarms. Its screw terminal block is designed to easily connect and disconnect to the logger body, while keeping the wiring to the terminal block.

The Process101A is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
