I would at least get a sinking swimming pool thermometer. Throw it in on several spots where you have livescope temperature readings and compare.

Cheap pool thermometers are not typically perfectly accurate for absolute temperature. However, they usually do have good repeatability.

If pool thermometer reads at 55, where livescope says 56; and 62 where livescope says 63, then your livescope is probably reading fairly accurate.
