I would be very tempted to purchase a Tel-Tru dial thermometer.

Basically if you can see the dial, you can see it accurately. I have one and wouldn't run a darkroom without one. Whilst I can see the nice things about electronic thermometers, batteries are a pain to live with.

I bought mine in Melbourne in the Braeside area about 22/23 years ago. They are certainly available as they are used by some manufacturers who monitor water and/or fluid temperature and also in the food industry, which Moorabbin (an adjoining suburb) has many food processing plants.

Do a search using Tru-Tel first to see what they are about, then do the same search but with pages from Australia only.
