The Eco Sensors DL-3 data logger is a modified AEMC Instruments (Chauvin Arnaux) model L430. The modification is adapting the logger’s input to be compatible with the output plug of our instruments (a 3.5 mm "miniature stereo" 2 circuit plug), The  Eco Sensors instruments that work directly with the DL-3 logger are the C-21 and the C-30ZX. Some other Eco Sensors  instruments can be factory modified to work with the DL-3. Usually this is just adding a cable terminated with the 3.5 mm plug.  However, the scaling used should be reviewed with tech support at Eco Sensors.
