Bellingham + Stanley Ltd., a UKAS accredited calibration laboratory number 0834, offer a number of different calibration
materials for verifying and calibrating refractometers and polarimeters, traceable to NIST, ICUMSA and/or PTB.

Following a three day re-assessment by UKAS in October, the laboratory accreditation under ISO17025 (general requirements for the competence of testing and calibration laboratories) for Testing and Calibration has been renewed allowing further certification of liquids up to 1.62RI (now 1.3 to 1.62) and over a wider wavelength range for polarimeter CRM's.

Further products are to be launched as a result of this new extension.
