ASTM 温度计

NIST traceable A.S.T.M. thermometers.

A.S.T.M is an American standard. 

These thermometers are manufactured according to the E-1 specifications of the American Society for Testing and Material (A.S.T.M.).

The colour of the glass of our A.S.T.M thermometers is standardized in yellow giving a much better reading than the white back, mainly for mercury filled thermometers. This is a quality choice even if the white glass is usually less expensive than yellow.

Graduation lines are fine and easily readable.

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. Even if you can feel a slight relief on the glass, the thermometer is not engraved.

Every A.S.T.M. 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 68 countries worldwide.

The A.S.T.M thermometer is fully marked on the back with the ASTM number, the purpose and ASTM method. If an A.S.T.M thermometer has an equivalent I.P, both standards are printed on the back of the instrument.

Delivered with Conformity and Traceability Certificate.

On request, can be supplied with "EU" Traceable Calibration Certificate or "EO" Official Calibration Certificate
