Overview
The HI96822 seawater sample sodium chloride refractive analyzer is a rugged, Portable waterproof device from the HANNA brand that utilizes refractive index measurement to determine salinity in natural and man-made seawater, seawater or brackish water. It eliminates the uncertainty of mechanical refractive meters and is suitable for home, laboratory or field use. After simple calibrating, the instrument can measure refractive index and temperature in seconds and convert to practical salinity units (PSU), parts per thousand (ppt) or specific gravity (S.G. (20/20)). The conversion algorithm is based on the physical properties of seawater, ensuring accuracy and reliability.
Features
1. Dual LCD display, the temperature reading is displayed below the measurement value;
2. ATC, automatic temperature compensation;
3. BEPS, low battery reminder to ensure accurate and effective readings;
4. IP65 waterproof, suitable for laboratory and field measurement;
5. Fast and accurate measurement, 1.5 seconds to quickly display the measurement results;
6. A little calibrated, with distillation water or deionized water calibrated;
7. Trace samples, only 2 drops of samples are required;
8. Automatic shutdown, no automatic shutdown for three minutes;
9. Stainless steel sample chamber, easy to clean and anti-corrosion;
10. Easy to operate, just drop the sample button reading, simple and fast.
Principle
The HI96822 determines salinity by measuring the refractive index of the sample. The user first calibrates with distillation or deionized water and then introduces the seawater sample into the sample well. The instrument measures refractive index and temperature in seconds and converts to PSU, ppt or specific gravity units using algorithms based on the physical properties of seawater. Automatic temperature compensation ensures accurate measurement results in the range of 0 to 40 ° C.
Applications
Natural seawater, artificial seawater, seawater, brackish water
Steps
1. Calibrate with distillation or deionized water;
2. Drop the seawater sample into the sample well.
3. Press the button to start measurement;
4. Wait for about 1.5 seconds to read the result.
5. The instrument automatically shuts down (after three minutes of use).
Notice
- Make sure to calibrate with distillation or deionized water before use;
The sample volume should be at least 100 μL to completely cover the prism.
- Pay attention to the battery level, the instrument will remind when the battery is low;
- Avoid use in extreme temperatures, the temperature compensation range is 0 to 40 ℃;
- Use stainless steel sample chamber and Glass prism during cleaning to prevent corrosion;
- The instrument needs to be restarted after automatic shutdown.
