The SP-1000-2X Precision Temperature Data Logger shares the same features as the standard Spectrum 1000 temperature data logger model with the exception that the 2X unit has two external temperature channels and no internal temperature channel.
The SP-1000-2X is compatible with EPT-010 Temperature Probes. Temperature channel 1 is located on the lower connector and channel 2 is located on the upper connector (see enlarged picture).
