Glass thermometers are designed for measuring body temperature whether it is orally taken or through insertion of the rectum. Glass thermometers have two different coloured spirits to differentiate the between the two applications with blue suited to oral use and red suited red for rectal use. Glass thermometers are inexpensive and portable making them ideal to store at home as part of your home first aid kit. In our glass thermometer range we have included multipacks designed for the medical profession which represent exceptional value.
Coloured alcohol spirits are commonly found inside glass thermometers instead of mercury due to concerns over mercury’s toxicity.

A no frills basic thermometer. Good clear display and easy to use.

Accurate. But springs a little fiddly.

I am happy with this, it does the job - However, if the back was even slightly concave instead of flat so it sat on the pipe, to make a better contact point, it would respond a bit quicker. However - For the money - A very decent unit. (2 different length springs supplied - Good!)
