The Hobo® thermocouple family of dataloggers measures temperature with three industry-standard thermocouples. Any Type J, K, or T thermocouple probes with standard subminiature connectors can be plugged directly into the units. Each logger includes cold-junction compensation, and two measurement ranges for optimal resolution and accuracy, says the manufacturer. More than 32,000 time-stamped readings can be stored in nonvolatile memory. The data is then read out to a PC.
