The self-recording voltmeter S-Recorder-L is the oldest in the S-Recorder line in relation to the S-Recorder-E, it has two main differences: a built-in DAC of 12 digits with 2 channels and an amplifier with more sensitive ranges, which allow to work directly with sources with weak signals, such as thermocouples and so on.
