SKU HI96821
The HI96821 is a rugged, portable digital refractometer designed for sodium chloride (NaCl) measurement. The HI96821 displays NaCl concentration four different ways: g/100 g, g/100 mL, specific gravity, and °Baume. The instrument’s high accuracy and simple operation gives reliable results each and every time. All readings are automatically compensated for temperature variations and displayed with a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.

Features at-a-glance:

- One-point calibration: Calibrate with distilled or deionized water
- Small sample size: Sample size can be as small as 2 metric drops (100 μl)
- Automatic Temperature Compensation (ATC): Samples automatically compensated for temperature variations
- Quick, accurate results: Readings are displayed in approximately 1.5 seconds
- Dual-level LCD: The dual-level LCD displays measurement and temperature readings simultaneously
- Stainless steel sample well: Easy to clean and corrosion-resistant
- Battery indicators: Battery percent level remaining at startup and low battery indicator
- Automatic shut-off: To conserve battery life the meter shuts off automatically after three minutes of non-use
- IP65 water resistant protection: Water resistant ABS plastic casing designed to perform under laboratory and field conditions.
