Glass Thermometer -10 to +50C 300 mm for Measuring Water Liquid Home Brew Win...

These are pretty good liquid in glass thermometers and found this to be easily accurate within 1 decree C, compared with a range of other laboratory grade thermometers that I have.

Very thin column; can be a little hard to see in some light. Otherwise do the job.

Very accurate thermometer and easy to read because, being -10 to +50 degrees centigrade, the markings are less cramped than on a 100 degree type. Obviously it's only useful if you're not measuring very hot temperatures. I use it when making up fresh water for my tropical fish and it's perfect for that - even doubles as a stirrer when I add the dechlorinator once I've got the temperature right.

Appears to be accurate and comes with a protective plastic case.

I am using this to check my other thermometers in the garden and greenhouse etc. Its very sensitive and will pick up the heat from your hands and sunlight so keep it away from any source of heat to get an accurate reading. Its well made and great value. spot on.

High quality scientific thermometer, -10 to +50. In my case, for monitoring the temperature of refrigerators.

Ordered six thermometers. Quick delivery parcel arrived in a few days. Some of the thermometers do work, but in some of the thermometers the column of spirit has air bubbles trapped in it so they don't work.
