Hand held refractometers overview
The use of a hand refractometer facilitates convenient and rapid measurement of concentration in a number of liquid and semi-solid samples.
Food applications include the measurement of sugar in grape must and other fresh fruit, processed food, sugar solutions and beverages. Starch, honey and salt solutions may also be measured.
Hand held refractometers are also commonly used to control blend ratios of various industrial liquids. Chemical blends such as glycols, battery acid, heat exchange fluids, automotive antifreeze, aviation wing de-icing chemicals and jet fuel ice inhibitors can be controlled easily whilst measurement of industrial fluids such as coolants, quenchants and hydraulic oils are commonplace.
Bellingham + Stanley offers a complete choice of hand held refractometers starting with the E-line economy range of optical models for use by hobbyists and within light industrial applications to the latest OPTi digital models that provide not only the most accurate performance in it’s class but also repeatability when switching between users.
E-Line “Economy” Range
The low cost models within the E-line range of hand held refractometers are specifically suited for light industrial use within small to medium sized businesses and by hobbyists handling fruit, beverages, confectionery, jam, honey and other sugar based products as well as for calculating concentration or blend ratios of heat transfer fluids like glycol, antifreeze, cutting fluids and quenchants.
The e-line gemological refractometer has a refractive index range up to 1.81 RI facilitating the measurement of precious and semi-precious gemstones.
Eclipse “Professional” Range
Since its launch in 1999, the Eclipse refractometer has become recognised as one of the World’s most reliable and robust optical refractometers on the market today. Manufactured in the UK using the latest techniques, Eclipse refractometers feature a bright field of view, a unique sample “dribble feed” and are sealed against moisture ingress.
A selection of scale types covering a wide range of common applications is available from within the Eclipse range as well as the unique Low Volume Brix Models that are favoured by zoologists and entomologists for having the capability of measuring samples of less than 1-microlitre such as nectar.
OPTi digital Range
Bellingham + Stanley OPTi digital hand held refractometers are manufactured in the UK as highly reliable premium quality instruments suitable for use in the harshest of environments.
There are many different models within in the OPTi family covering not only the commonplace food, beverage and chemical instruments but also life science, automotive, heat transfer and even customer specific applications.
