Electrocorder Index

Electrocorder is a UK based manufacturer of voltage and current dataloggers for industry. Unlike other manufacturers, all Electrocorder instruments are "off the shelf", as opposed to bespoke solutions.

The Electrocorder company is privately held, with several key industrial shareholders.

The main product sectors for Electrocorder are Power/Energy Loggers/Recorders, Voltage Loggers/Recorders and Current Loggers/Recorders.

Power Recorders for power (kW) and energy (kWh) surveys are widely used for energy reduction surveys.

Voltage Recorders (AC & DC), single, two and three phase loggers are suitable for Voltage issues and Voltage Optimisation Surveys.

Current Recorders (AC & DC) are for single phase and three phase circuits for load and energy surveys, Generator Sizing and transformer or feeder/circuit loading issues.
