THERMOMETERS: Variety

$ 4.00$ 159.95 excl. GST

We supply a wide range of thermometers including kerosene-spirit filled, Red-fill (red spirit) and ‘Green fill’ (green kerosene), Clinical, Digital-Infrared ranging from 50°C to 600°C. Various accessories like Suspension clamp, Stand available too.

Some may arrive with spirit columns separated which can happen to any brand.
Restoration methods are as follows:
1) Stand them vertically (bulb end down) leaving them for a few weeks. (This is the simplest and easiest method)
2) Place them in water and slowly bring it to the boil.
3) Gently heat bulb at base over a spirit lamp flame. This forces the spirit up the column until it gets to the top, eliminating gaps in the spirit column as it moves.

WARNING!
Wear safety goggles and a laboratory coat when doing this. If the liquid is put under pressure at the top, the bulb at the base will burst.
Always store liquid (particularly spirit) types vertically, bulb end down, to avoid the possibility of their columns splitting – recommended by manufacturers of liquid types.
