Feature Highlight

Pour through refractometers are designed for measuring cane or beet juice in a sugar mill. This design has two important benefits: cleaning becomes part of the sample loading process and measurement time is reduced because one sample is poured in after another making the design attractive for seasonal operators. The small funnel design forces improved sample flushing by increasing the number of sample pours.

Model	Specification	Features and Benefits
	Measurement Range: 1.33 - 1.53 RI; 0 - 95% Brix Accuracy: 0.00004 RI, 0.03 Brix Electronic Temperature Control: Fixed temperature selection: 20°C and 25°C	The J57HA’s simple interface and easy to clean prism surface make it one of our most popular models for the sugar industry. Temperature control to 20°C and 25°C makes it perfect for molasses and high Brix samples. Measurement speed can be improved by using Temperature Correction in conjunction with Temperature Control, allowing measurements to be made accurately almost as soon as the sample is placed on the prism.
	Measurement Range: 1.33 - 1.53 RI; 0 - 95% Brix Accuracy: 0.00004 RI, 0.03 Brix Electronic Temperature Control: Flexible temperature selection between 15°C - 50°C	The J157-CC-AM is also quite popular with sugar factory labs. The non contact cover (CC) with built in electronic heating and cooling improves performance in harsh conditions. The Auto Measure (AM) feature allows the closing and opening of the cover to start and stop the measurement eliminating the need for the operator to touch the interface. Very popular for factory floors where air temperature varies dramatically: cold at night and hot during the day.
	Measurement Range: 1.33 - 1.53 RI; 0 - 95% Brix Accuracy: 0.00004 RI, 0.03 Brix Electronic Temperature Control: KVP: Select any temperature between 15°C - 30°C PTW: Select any temperature between 15°C - 40°C	The J157-PTW can be operated as a pour through refractometer when measuring juices and then by loosening one thumb screw and lifting the hinged presser the instrument can be used like a J57. This allows the J157- PTW to measure molasses and other high Brix samples. The J157-KVP has a vertical prism that allows suspended solids to fall past the prism surface instead of on to the prism. The small funnel volume design with integrated over flow funnel increases sample flushes and reduces spillage. The J157-KVP is often favored in applications with highly turbid samples.
