Professional grade optical handheld refractometer with clear field of view and large rubber handgrip for easy measurement in harsh environments. A durable refractometer for measuring chemicals as part of raw material control as well as for controlling the blend ratios of industrial solutions. Made in UK. IP65 rated against moisture ingress.

This high quality refractometer has been designed with specialists in mind. The 1.33-1.42 refractive index scale is in fact the primary scale from which all other scales are derived. You could, therefore, use this refractometer for almost any application - providing you had the information required to form your results. For most users we recommend our application-based refractometer, however for specialist use this can be used for chemicals, surfactants, detergent blends, fertilisers, diesel fuel additives, and anti-freeze fluids.
