Digital Refractometers offer ±0.1% and ±1 ppt accuracy.

Press Release Summary:

Series DR Refractometers read and measure salt/salinity from 0-28%, refractive index from 1.3330-1.3900 nD, and Brix from 0-35%. Units feature 0.75 in. digital LCD readout to eliminate misreadings. Microprocessor provides automatic calibration, automatic shutoff after 3 min, and low battery indicator. Water-resistant design protects electronics from wet environments. Suited for samples up to 100°C, models include stainless steel plate for optical sample prism.

Original Press Release:

Digital Salt/Salinity/Brix Refractometers - Four (4) Models - High Accuracy ±0.1% and ±1 PPT

Kernco Instruments Co., Inc. is pleased to introduce four (4) digital salt/salinity refractometers designed to read and measure salt/salinity from 0-28%, as well as the measurement of refractive index (nD) from 1.3330 to 1.3900, read and measure
brix/salt/refractive index in ranges of 0-35% brix, 0-28% salt and refractive index from 1.3330 to 1.3900, the last model reads in salinity in parts per thousand with range of 0-280 ppt and it also reads in refractive index of 1.3330 - 1.3900.

General Information and Uses
These models are useful for controlling the salt level of brine solutions, measuring concentrations of salt water used in rinsing and cooking sea products, and checking salt content of holding tanks, aquariums and breeding ponds. Extremely useful in canning and preparation of food products by monitoring salt content. Models also measure salinity of saline solutions and seawater density (in parts per thousand and refractive index). Special Model DR-35-BSR also measures Brix % as well as salt %. Therefore this model is ideal for process operations where it is important to know the brix % and salt % for different food products on the production line. All models come with automatic temperature feature. All models are supplied with battery, carrying case and operating manual.

Measure percent concentrations in the plant with laboratory accuracy. As small, light and simple to use as optical refractometers but with a digital readout (0.75" LCD display) to eliminate misreadings that can occur with the optical refractometer. The sophisticated microprocessor provides automatic calibration, automatic shutoff after 3 minutes, a low
battery indicator, and a low power consumption resulting in over 2,000 tests per battery. Water resistant design protects the electronics from wet environments and makes for easy clean ups. This model features automatic temperature compensation. Use on samples up to 100°C. Models have stainless steel plate for optical sample prism.
