Density meters or Hydrometers with Density (g/ml) for the petroleum industry. MRA traceables. On the scale of these standardized hydrometers are indicated the standard, the calibration temperature, the surface tension, the individual number of the instrument, the serial number. Number written on the instrument.
An indelible reference line engraved on the rod indicates any displacement of the scale. They are adjusted at 15°C with Official Primary Standards for low surface tension (16 to 35 mN/m) for reading below the meniscus. Systematically delivered with a Certificate of Conformity and Traceability.
