    Hi there,
    We’re conducting a Gauge R&R on a a temperature data logger and themrocouple system we will be using for our Six Sigma Project. The problem we are having is finding a stable temperature source that will give us less than 5 Degrees C variation at temperature of around 230 degrees C (which rules out an ice bath).
    So far we have tried our vapour phase reflow oven. On any particular day this is great but over the course of a week when the Guage R&R has been completed the oven warms up. This is down to the fluid inside and after speaking to the manufacturer this is apparently expected.
    We are now in the process of trying the vat of molten solder in our wave soldering machine. This isn’t quite as good on the day but will hopefully prove stable over the course of the whole test. We’ve even added heat sinks to try and smooth out some of the spikes in temperature we have seen.
    We’d really like to know if anyone else has ever run a Gauge R&R on a temperature system and had success. If so, what did you use to keep the temperature stable? If not, any advice would be greatly appreciated.
    Thanks
    James

    James,
       I would suggest contacting the manufacuter on this one. They should have some good testing methods for your application.
