Hanna Instruments thermometer for temperature from a fixed wall-mounted instrument, one model.
HI146-00
This Hanna Instruments thermometer measures temperature from a fixed wall-mounted instrument.
A thermometer screwed to a wall is always in the same place, so its readings are comparable day to day and it cannot be borrowed. That is what makes it the right instrument for a room whose temperature is part of a record.
Most wrong temperatures are not the instrument's fault. A probe placed too shallow, read before it settled, or put in the thinnest part of a piece of food gives a confident number that was never true of the product.
Insert to the depth marked, into the thickest part, and wait for the reading to stop moving. Check the instrument against an ice-water slurry periodically — that is a real reference point, and it costs nothing.
Mount away from doors, lights and vents; a thermometer next to any of them reports that fixture, not the room.
Supplied as one model.
