Digital thermometer?

[welly]

Any recommendations/links? Nothing too silly, just within spitting distance is good for me!

Dick Smith's usually have a good accurate and inexpensive probe digital thermometer.

Cheers Steve - I found one at DSE which was nice and cheap. Going to test it against a few other thermometers for accuracy. Might need a chat with you re BTZS sometime this weekend if you're about!

I have several of these. I am very happy with them. They are all within 1/2 degree of my Kodak process thermometer, waterproof, respond fast, and are cheap enough, and can cover the range from freezing to beer-mashing temps.

I found a waterproof thermometer in a gormat food store. Make sure its waterproof. Cost was $14.00 US Dollars. In chekcing it against a color thermometer it was spot on and now is wat I use all the time!

I've used a bunch of them. My favorite is: http://www.thermoworks.com/products/...st/rt600c.html

I've had a few expensive ones over the years. The basic Kodak process thermometer works
a lot faster and better.

I did a bunch of research on this... Most thermometers are repeatable. Very few are actually accurate. Often, they have NIST certifications. It's meaningless. I would also doubt the accuracy of any glass thermometer. (Kodak, shmodak.) Just understand that what you need is "repeatability". It doesn't really much matter what the temperature actually is - unless you are trying to help someone else, which is almost impossible since agitation differs so much, etc.

Some are accurate "at points". This means at 0C and 100C, usually. Doesn't help you at the temperature we like to develop at, around 20C or so. They don't even measure it.

The ones that are accurate cost around $500.

Given this, might be good to get something that won't break easily... so you can keep using it for a long time.

We used to have a scientific supplier just a couple blocks away who sold nothing but thermometers, an actual warehouse of all kinds of them, but mostly glass. And in this R&D town, the world epicenter of biotech and pharmaceutical research, plus UCB, you can be pretty certain those thermometers were damn accurate! But one gets what one pays for!

I have a couple of digital thermometers; I forget what brand. I've compared both with a Kodak process thermometer that I got years ago. They're pretty much linear, but closely matches the Kodak at about a single point or within a small range. So, I calibrate the digital thermometer to the Kodak at 70 deg.F, which is the temperature about which I really care. Within a few degrees of 70deg.F, it will still be very close.

So, which is off, the Kodak or the digital thermometer, I'm not sure? But the nice thing about the Kodak is that it's a constant I can use as a standard. I don't care about whether it's perfectly accurate, as long as it's repeatable. (Which it is.) When I do calibrations, everything adjusts around that standard.
