These hydrometers are manufactured according to the American standards from the last ASTM E2995 Committee of the AMERICAN SOCIETY FOR TESTING AND MATERIAL
their thermometer is filled with a BLUE SPIRIT much less toxic than mercury.
***References called ""SIMILAR to API"" are not yet considered in the ASTM standard , however, are made to the customer's request ***
The scale of the hydrometer is fully marked with all the reference norms, the calibration temperature, the surface tension, the individual number of the instrument and our BIO-TEMP® logo.
A benchmark is engraved on the stem to show any displacement of the scale.
Systematically delivered with a Traceability and Conformity Certificate
On request, can be supplied with "EU" Traceable Calibration Certificate or "EO"Official Calibration Certificate
