The Agilent 34307A thermocouple kit contains 10 J-type thermocouples. Each thermocouple is 180 cm (72 inches) long, of 20 gauge wire with a Teflon outer jacket and is unterminated.

The Agilent 34307A is compatible with the Agilent 34970A Data Acquistion/Switch Unit. The 34307A can also be used with the Agilent 34401A, however, an external program is required to convert the voltage measurements to temperature and an ice bath or electronic reference junction must be used.
