    I broke my thermometer a while ago and went to get a replacement last night. I was in a hurry as I had a bus to catch so I went into a local home made wine supplies shop where I bought the last thermometer.

    I found one, paid for it and left.

    On the bus on the way home I had a look at it and it would appear tha I picked up a hygrometer instead!

    I'm going to have to make some more wine now to get some use from it!

    Steve, you better not drink that wine before you get yourself that thermometer next time.

    As things are going, grapes have a better chance than film. Smart buy.

    I find thermometers are like religions. I have five that all read differently, and I don't know which one to believe!

    That's why it's a good idea to have only one (until it breaks).

    I bought a batch of a dozen of more scienctific lab grade thermometers at a clearance auction for $40 this past spring.

    5-6 were cracked. Of these I carefully while outside dressed in mondo PPE salvaged the mercury, and turned it in to the HHW depot.

    One good one is neat; it runs from -10C to 400C and is about 2 feet long. I will reserve it for the next time I need to better judge the temperture of the product condensing off of the still. (ha ha, not busy with that a the moment; I have more than 10l of a 20l batch 40% ethyl still stockpiled for quick drying film, an other more relaxing endeavours.)

    One is made for biological processes. It is 4" long, and is calibrated between 36 and 43C. It now lives in the output of the circulating pump for my e-6 and c-41 tempering bath with a sharpy marker dot over the 100F equivalent.

    The most useful one is good for -10 to 100C, and is long enough to be calibrated in 0.2C increments. It is now my reference thermometer, against which a host of other lesser ones in the darkroom are calibrated against. It does not come out of its protective sleeve very often, for it is long and fragile.

    I think, given the original post, it will be a buoyant one instead.

    It might serve as a stocking stuffer for your wife as an early warning system for those "bad hair days".:D

    I have a reference thermometer which I don't use for anything except calibrate my other thermometers against

    I then have about 6 or 7 thermometers which I use and they all read the same temperature within 0.2C of the master.

    Inevitably we all loose a thermometer every so often through accidental damage - but this way I maintain my processing temperature

    It is better to check them against a mixture of water and ice. Make sure that the ice and water have equilibrated. Good thermometers will have a line showing where the liquid should reach. By using ice the temperature is not dependent on altitude.

    Does this qualify as a freudian slip? :smile:

    No, a Freudian slip is worn under a Jungian skirt.

    My question is: Does one buy a Freudian Slip at Victoria's Secrets or Friedrick's of Hollywood?
