The 1560 is a reference thermometer capable of reading SPRTs, RTDs, thermistors, and thermocouples. Accuracy to ±0.0013°C. The stack consists of 8 different modules which fit together to do any type of thermometry. Each module stacks behind the preceding one, with each module adding a new function to the overall system. No boards or software needs to be installed as the module will automatically reconfigure the software. You can obtain some of the modules, or all of them depending on your needs.
There are nine thermometry modules: an SPRT module, a high-temp PRT module, a PRT scanner module, a standards thermistor module, two 1000-ohm PRT modules, a thermistor scanner module, a precision thermocouple module, and a thermocouple scanner module.
