Density Hydrometers (g/ml)
ISO, BS, DIN, NF... MRA Traceable.
General Purpose at 20°C.
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, the serial number and the ALLA FRANCE logo.
With a benchmark engraved on the stem to show any displacement of the scale.
They are calibrated according to the following surface tensions:
from 0.600 to 1.000 g/ml= 16 at 35 mN/m (low tension)
from 1.000 to 1.300 g/ml= 55 mN/m (medium tension)
from 1.300 to 2.000 g/ml= 75 mN/m (high tension)
