Typically used by entomologists or zoologists, this especially adapted optical handheld refractometer fitted with a 45-80 Brix scale is often taken in to the field to measure nectar in flowers as part of deforestation studies as a sample volume of only 1 micro-litre is required to take a measurement. IP65 rated against moisture ingress.
The low volume performance of this modified Eclipse refractometer is achieved by using a special prism flap which has a precision machined face enabling extremely close contact with the prism and hence a very thin film of sample.
