Ok, just to be kosher here with your thread, it was 32F last night. Tonight is supposed to be 33F.
Thermometers merely measure the thermal energy a substance possesses…or for some folks perhaps an overall gauge of molecular movement.
Its basically the same measuring a substance with high thermal energy or low thermal energy as long as one has the proper measuring range in an instrument.
At first when we tried a fancy Uber accurate scientific thermometer it was way too complicated. Accurate, but crazy hard to get point data.
So it came down to finding a reasonably accurate IP67 waterproof thermometer that would have a small measuring footprint and the proper temperature range and consistency where the data wasn’t being taken at an extreme of its range of measurement.
Thus we
ended up with these handy little guys. They have a wide range -58°F to 572°F (-50°C to 300°C). These can be easily stuck in bonsai media and if freezing is occurring, a piece of a meat skewer can be placed in the observing position between measurements. I’ve made 15 trials of15 measurements each to date. Repeated measurements were within 0.2F, mostly less. It even has a lighted display if night/dark readings need to be taken.
Thus the meat thermometers get the nod for citizen science! The cool thang is if the probe is cleaned off after one’s measurements are complete it can be used on your steak… or ice cream!
