Please note: 

- These hydrometers are made to order and have a lead time of approximately 5 weeks 

- If you require a calibration certificate, these can be provided at an additional cost and will need to be ordered alongside the hydrometer

BS 718 : 1991 is generally aligned with ISO 387 and ISO 649. The specification includes five series and three sub-series of hydrometers. They are calibrated using the accepted units of grams per millilitre (g/ml) and are adjusted at 20°C. The following specification refers to L50 Series. All hydrometers can be supplied with UKAS certification, certificate traceable to Recognised National Standard or Statement of Conformity, if required.
