Manufactured to British Meteorological specifications, these thermometers are lowered to a selected depth in the soil via a pointed steel tube. They are solid stem mercury-in-glass type, and are fitted into a transparent sheath made of stout glass tubing. The bottom 40 mm of the sheath is filled with paraffin wax in which the bulb is embedded. The thermometer therefore responds quite slowly to temperature changes and can be raised to the surface for reading.
A flange controls the exact depth of sinking and ensures sufficient projection above ground to keep out standing water, and the tube is sealed with a copper cap.
The insulated pattern themometer is left in the soil, with the added advantage that readings can be taken in-situ without disturbing the instrument. The lower portion is placed vertically in the earth with the bulb at the required depth, and the insulated thermometer stem and opal scale are supported on a black-enamelled mild steel angle bracket. The range is -10 to +55°C divided into 2.0°C intervals.info »
