Reichert® Standard Precision Analog Refractometers

Affordable and rugged, these are IP67-rated dustproof and water resistant, making them the highest rated handheld meter on the market. Suitable for tough environments on the processing floor as well as in the field. Shock resistant sealed housing. Ideal for measuring Brix concentrations in food and dairy applications. A specific gravity model for testing coolant and batteries is also available. 1-year warranty.

Used in the food industry to monitor the concentration of dissolved solids in aqueous (water) solutions. Popular applications include: Condensed skim milk, whey, brines, soft drinks, juices, and coolants such as glycol. 

How it works: Simply place a drop of the solution on the prism, lower the cover and look through the eyepiece. Solids will be indicated by a distinct line across an illuminated scale. Scales are often graduated in Brix (percent of dissolved glucose). Although this scale does not directly indicate the percent dissolved solids by weight of the product being measured, the result does give the relative concentration of dissolved solids compared to other similar solutions.
