You can purchase an assembled temperature probe, or you can construct one yourself. The advantage to building your own is you can create a temperature probe with low thermal mass. When making measurements on the bench it is important to have a low thermal mass as many of the DUTs on the bench will be small. The 34410A and 34411A Digital Multimeters are a good choice for temperature measurements as they have built-in algorithms to support many common Thermistors, RTDs and PRTDs. Additionally, the 34410A Bench Multimeter has a built-in data logger, limit testing, and statistics. Watch video for more: http://www.youtube.com/watch?v=C0GhN5Dt8vg

As I know, Agilent uses YSI thermistors, possibly the 44xx6 at 10KOhm and the DMM is (?) calibrated/programmed with the appropriate parameters or R/T table. Unfortunately I am working with another precise thermistor manufacturer with different R/T curves. Can I re-program my DMM for that thermistor? Which specific thermistor is the "typical" for the DMM? If we knew the exact R/T curve we could calculate the percentage of error for a specific temperature span.
Thanks for any help!
