Here is your chance to contribute to some work we are doing on housing/heating for colder climates.
You will need:
1) A coldframe or cloche type outdoor enclosure.
2) An infra-red non contact thermometer.
3) A general purpose air temperature thermometer.
Methodology:
The object is to get some paired readings. We need:
1. Ambient (outdoor) air temperature
2. Ambient air temperature inside the unit
3. Carapace temperature (top of shell) with IR spot thermometer
4. Plastron temperature (bottom of shell) with IR spot thermometer
Several sets of measurements in a wide range of weather conditions are needed from each contributor.
It would also be useful if you could post a photo of the unit (and your results) in this thread.
