NUMBER 1 IN LUBRICANT CONDITION MONITORING STANDARDIZED HYDROMETERS According to ISO 649SP - Petroleum Products Compact, GESERCO hydrometers are particularly easy and convenient to use. (Highlights any possible displacement of the scale Density measurement of petroleum products in g/ml Density determination of fluids having low surface tension (lubricating oils and fuel oils.) Cost-effective test Rapid test Other models are available: Length 270 mm or 335 mm ISO, DIN, AH or ASTM conformity Thermo-hydrometers Hydrometers Hydrometers are conform to ISO 649SP standard and are MRA traceable. The scale of the hydrometer is marked with the Standard it conforms to, calibration temperature, surface tension, individual number of the instrument, and serial number. They feature a benchmark engraved on the stem in order to highlight any possible displacement of the scale. They are calibrated at 15°C and designed for the density determination of fluids having low surface tension (16 to 35 mN/m) such as lubricating oils and fuel oils.
