12 Channel Digital Thermometer with Datalogger features a large, bright screen and connections for six thermocouple types (J, K, E, T, R, S).

Users can simultaneously display channels 1-8 or 9-12 and store 99 readings manually, or up to 20 million readings with date and time stamp using a 2GB SD card. All data is saved in MS Excel format for further analysis.

The user programmable sampling rate is adjustable from 1 to 3600 seconds with Min/Max, Data Hold, and Auto Power Off. Data can be recorded from all 12 channels simultaneously onto an SD card for later analysis.
