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.

I had the same type of thermometer before until the builder had to replace the window. After 5 years the white plastic had turned yellow and the then-type of outside window glass fixing had hardened and disintegrated.Buying the new version with suckers I found that the suckers would not work and I had to coat them with Evostik glue.
