Thermometers for maple sugaring

Must read the finish point (~219 F) with margin: range to at least 225 F, graduations 1/4 F or finer (NAMSPM); 'calibrated to at least 30 degrees F above the boiling point of water' (Cornell); 50-300 F (UNH).

No pick

Only range could be verified; accuracy and graduation interval were absent from every hobby listing read.

What matters

How to judge thermometers

Each criterion names the extension or manual source it comes from; 'synthesis' marks our own reasoning.

1
Must read the finish point (~219 F) with margin: range to at least 225 F, graduations 1/4 F or finer (NAMSPM); 'calibrated to at least 30 degrees F above the boiling point of water' (Cornell); 50-300 F (UNH).
NAMSPM2 p.148; CORNELL-NB p.5; UNH · verified
2
Calibrate against boiling water the same day and place; a 1 F error = ~2.5 Brix; verify finished syrup with a hydrometer.
NAMSPM2 p.148; CORNELL-NB p.99 · verified
3
Dial (pan-mounted, 0-50 'degrees above' or 20-240 F) vs stem/candy vs digital; mercury thermometers are a contamination risk - replace.
NAMSPM2 p.148 · verified
4
Stated accuracy and resolution are the comparable specs; most hobby candy thermometers do not state accuracy.
