Overview
The HI96821 refractometer is a sodium chloride measuring instrument for the food industry that converts the Refractive index of liquid solutions into sodium chloride content values. The instrument uses automatic temperature compensation technology for fast and accurate measurement. Only two drops of sample need to be calibrated with distillation water or deionized water to obtain results in seconds. It supports four unit displays: g/100g, g/100mL, specific gravity and ° Baumé Baumé. Not suitable for seawater salinity measurement.
Features
1. Dual LCD display with temperature reading below Measured value
2. ATC automatic temperature compensation
3. BEPS low battery reminder function to ensure accurate reading
4. IP65 waterproof rating, suitable for laboratory and field measurement
5. Fast and accurate measurement, 1.5 seconds display results
6. A little calibrated, using distillation or deionized water
7. Micro sample requirements, only 2 drops of sample are required
8. Automatic shutdown function, no automatic shutdown for three minutes
9. Stainless steel sample room, easy to clean and anti-corrosion
10. Easy to operate, drop sample button reading
11. Equipped with ABS heat shrinkable plastic carrying case
Principle
The instrument automatically converts the Refractive index to sodium chloride content by measuring the refractive index of the solution. Internationally recognized reference unit conversion and temperature compensation methods are used to ensure measurement accuracy. After the sample is calibrated with deionized water or distillation water, the instrument completes the refractive index measurement and calculation in a few seconds, and displays the results in selected units.
Applications
Food industry
Steps
1. refractometer calibrated with distillation or deionized water
2. Add two drops of the sample to the sample chamber
3. Press the button to read and wait about 1.5 seconds for the measurement result to be displayed
Notice
Not suitable for salinity measurement
• The calibrating must use distillation or deionized water
• The minimum sample volume is 100 μL, and the prism needs to be fully covered
• The instrument has an automatic shutdown function, no automatic shutdown is required for three minutes
• Pay attention to low battery prompts to ensure measurement accuracy
• Keep the sample room clean to prevent contamination from affecting the measurement results
