The model 45-46 Eclipse refractometer which measures glycol % is a useful instrument for engineers working on air-conditioners, heat exchangers or even pasteurisers - and because it’s an Eclipse refractometer it is IP65 rated against moisture ingress.
Our refractometers for aviation include an OPTi designed specifically for determining the concentration of aircraft anti-icing fluids (glycol & additives). When mixed with water prior to application to an aircraft’s wings the anti-icing fluids prevent ice build up during take-off.
Our range of optical and digital refractometers for industrial applications are Made in the UK by Bellingham + Stanley.
