Densimeters ranges

About aerometers and densimeters with or without built-in thermometer:

– the ones from inland have the classic range from 0,07 to 0,07 units. Example: for diesel fuel you need a densimeter or thermo-densimeter from 0,790 to 0,860 g/ml;
– the ones from Germany have other ranges such as: 0,600 to 0,660 / 0,650 to 0,710 / 0,700 to 0,760 etc. or 1,000 to 1,020 / 1,020 to 1,040 etc. depending on the required precision and dimensions.

Note that the calibration in metrology is compulsory only when used in domains which can impair the health of humans (the notion of metrological verification is actually the user’s choice).
