Pico Technology Thermocouple Terminal Board The Pico Technology single-channel thermocouple terminal board allows wires to be attached to the data logger without soldering. The four input ranges (±50mV, ±500 mV, ±5 V and 4–20 mA) allow a wide range of other sensors and signals to be measured. The terminal board is designed to use with the USB TC-08 and is not guaranteed to work with other thermocouple data loggers. It plugs into a channel on the Pico TC-08 data logger and turns it into a 20-bit high-resolution data logger.
