Calibration & Accessories

For refractometer verification and calibration

At Refractometer Shop we have a range of refractometer verification and calibration materials, as well as accessories to help keep your refractometer in tip-top shape. Whether you’re looking for UKAS certified AG fluid, sucrose solution, replacement refractometers flaps, optical refractometer contact liquid or an inexpensive carry case for your digital refractometer, this is the area for you.

Our calibration materials vary between organic compound calibration oil that cover a range of 1.47 - 1.56 refractive index, long life aqueous AG fluids which cover 1.33 - 1.40 refractive index, and sugar solutions - often used by food and beverage manufacturers. Calibration materials can be bought as single bottles or boxes of 5 for your convenience.

Is your refractometer in need of regular calibration? Speak to us today to learn about our 12 month supply contracts of calibration materials. They could save you time and money, as well as removing the worry of making sure you're always stocked up with what you need, when you need it.

Find an Accredited Laboratory or Inspection Body local to your region

The accreditation body, UKAS serves the United Kingdom for the assessment of certification, testing and inspection, and calibration. For those not in the UK you may be looking for other internationally recognised standards. Bellingham + Stanley's calibration page has a directory to find an accreditation body in the economy where you require the calibrations, testing or inspections to be carried out.

Refractometer Calibration Materials up to 5 Decimal Place RI and up to 2 Decimal Place Brix Uncertainty


Calibration Oils

Calibration Oils are organic compounds that cover the range 1.47 -1.56 RI and cover the top end of the Brix scale. Calibration Oils have a shelf life of 12-months. They are ideal for calibrating refractometers that have temperature control in both food and industrial applications


AG Fluids

AG Fluids are aqueous solutions that cover the range 1.33-1.40 RI (0-40 °Brix equivalent) and have a shelf life of 12-months. They are ideal for calibrating refractometers that have temperature control in both food and industrial applications as well as instruments that have AG Fluid temperature compensation. AG Fluids are unique as they are low Brix and have a long shelf life.


Sucrose Solutions

Sucrose Solutions offer ease of use when calibrating instruments that do not have temperature control but instead rely on temperature compensation. They are also preferred by beverage, sugar and food producers as their components typically match the product being tested.

Did you know...?

Refractometer Calibration Materials from Refractometer Shop aren't just for handheld refractometers; they can also be used with benchtop refractometers such as the RFM refractometer series from Bellingham + Stanley. Take a look at the video to see how simple they are to use. 

Remember, your readings and results are only as good as your calibration. Refractometers work within fine margins and are delicate scientific instruments. Look after your refractometer and it’ll serve you well for many years to come.

Our calibration fluids are manufactured by Bellingham + Stanley and certified in their UKAS accredited calibration laboratory no. 0834 in accordance with ISO 17025:2017. Whilst we endeavour to send stock as soon as possible please note that calibration items are subject to a 5-10 working days lead time.
