They feature a special ring/hook that can be clipped on the glass, patented by Alla France (not supplied for thermometers with a diameter greater than 6.5mm)
The colour of the glass of our thermometers is standardized in yellow giving a much better reading than the white back.
Graduation lines are fine and easily readable. Even if you can feel a slight relief on the glass, the thermometer is not engraved.
The measurement scale is fused into the glass with a special manufacturing process makes it completely indelible and very resistant to chemical agents exept fluoridric acid and hot soda (to a lesser extent) because these 2 products attack the glass.
Every thermometer has an individual number printed on the back. This number is stocked in our data base and fully traceable to our Official Masters regularly controlled and traceable in over 72 countries worldwide.
On request, can be supplied with "EU" Traceable Calibration Certificate or "EO" Official Calibration Certificate
