Pipette: Kimble, disposable, rated at 20C, markings read:
5/10ml in 5/100
coupled with:
generic 9v digital multimeter with k-type thermocouple
(looks like a thin pair of wires with a tiny knob connecting
them at the end)
Melt pointed tip of pipette closed with blowtorch, insert thermocouple,
wrap teflon tape around midsection to fit 10/30,
reads my grandmother's rectal temperature at 232C, smooth as butter.
Aren't multimeters wonderful?
Total cost: $20
