e-corder units are used for the collection, display and analysis of signals from many types of laboratory instruments. They connect to Windows and Macintosh computers via USB, and are supplied with
Chart and Scope software.

Unlike many specialist data acquisition systems, e-corder can be used to collect data from completely different types of sources on different channels (e.g. pH, oxygen concentration, and temperature) because channel sensitivity and filtering is independently adjustable.

Replace your chart recorder, XY plotter, or oscilloscope (to 200 kHz), with e-corder to get the benefits of the latest generation of computer technology in your laboratory.

Typical instruments used with e-corder units include:

  • photometers and colorimeters
  • pH and ion meters
  • dO2 meters
  • temperature monitors
  • accelerometers and vibration sensors
  • load cells
  • pressure, force and displacement transducers
  • calorimeters
  • stopped-flow and other kinetics systems
  • potentiostats and galvanostats (see also EChem software)
  • chromatographs (see also PowerChrom software)

For more examples, see the research and teaching applications pages.

e-corder can be used with most devices supplying an analog voltage signal up to ±10 V.

e-corder connectors

The front panel of e-corder units have connectors for the analog input signals, an analog output signal, and a trigger connector so that recording start and stop times can be synchronized with other instruments.  

Analog inputs

Each analog input channel is fitted with an easy-to-use BNC connector. The gain of each input can be independently adjusted, in software, to record signals from microvolts to a maximum of ±10 V. Up to four input channels also have alternative 8-pin DIN connectors for connection of eDAQ Pods, or for signals requiring differential input. Each input channel also has a range of low pass filter settings from 20 kHz to 1 Hz.

Analog output

The e-corder unit can generate a voltage signal via its analog output sockets, giving bipolar (simultaneous positive and negative) signals up to ±10 V.


An external device can provide a trigger signal to the e-corder to synchronize recording.
