HR Hand RefractometerThese are precision instruments for determining the solid contents dissolved in liquids, suchas sugar, salt, serum protein in blood and starch. A few drops of the sample is placed on therefractometer prism and the index of refraction is measured. From this, dissolved solids canbe determined in seconds. This method is very useful for process or quality control of beetor cane sugar, fruit juices, jam, vegetable juices, soft drinks, and canned foods to name afew applications. The hand refractometer fits in every pocket! Delivered in a handy storagecase with conversion tables.

PR 20-series

This process refractometer has been developed for direct insertion into pipes

and boilers (Fig. 4) and is ideal for process control in the food , beverage, pulp

and paper, sugar and sweetener, and chemical industries, as well for separation

of products.

There is no need to install a bypass line. This simplifies installation in pipes or

boilers.

Installation

Installation of the

process refractometer

is simple and fast due

to the use of

standardized flanges

(Fig.5).

Depending on the

diameter of the pipe a

T-piece or adapter

has to be welded on.

Ex-Protection

The sensor is also in an ex-

protection version available.
