After my last two Imperial Stout Brewdays and peoples comments on efficiency and extraction, I thought I would test my thermometers.
Below are tests with a jug full of Ice & Water for the ZERO point and a pan of boiling water for the BOILING point.

The test subjects:

The Cold Test

All submerged in Ice Water:

My Cheap, from Hong Kong, regular brewday Thermometer in Ice Water reads 0.5c:
The glass spirit thermometer reads -2c in Ice Water which I was quite surprised at:
Another Cheap Hong Kong food thermometer reads 0.9c in Ice Water:
My £15 ebay purchased Thermamite 5 reads 1c though it only reads in 1 degree increments:

The Hot Test

The Thermamite 5 reads a 100c, which feels reassuring:
Cheap Food thermometer reads 99c:
My regular brewday thermometer reads 100c too:
The spirit thermometer reads 100.5c:

A fair range of inaccuracy but at least I know the ones I’ve been using are about the more reliable 🙂

A little chilli update, Jalapenos and Jal Purples coming along nicely in the grow room under the Envirolite, check the thermometer for the temp and humidity, under the staging is a little oil filled radiator to keep the plants warm. 🙂

Oh Yeah… note the “I can’t see where I’m putting my hand” syndrome 🙂 ha ha
