PCE Instruments, PCE‑DRG 2 Handheld Digital Refractometer for Sodium Nitrate Testing, Measures 0-41% Nano₃ / 1.3127–1.387 nD, Along with Automatic Temperature Compensation & IP65 housing

This professional-grade digital refractometer precisely measures sodium nitrate concentrations from 0 to 41% in water samples, with an impressive refractive index range of 1.3127 to 1.387 nD. The device features a clear LCD display showing both measurements and temperature readings simultaneously. With automatic temperature compensation and IP65-rated ABS housing, it delivers reliable results in various environments. The unit requires only 4-5 drops of sample and provides quick measurements in about 1 second. Its funnel-shaped stainless steel sample holder protects the glass prism, while the built-in light source enables testing in poor lighting conditions. The refractometer operates via a rechargeable battery and includes convenient features like one-button operation and auto power-off after 1 minute of inactivity. Measuring 5.7 x 1.8 x 1.1 inches and weighing just 0.25 lbs, this compact instrument comes complete with a sturdy carrying case, pipette, and charging cable. It's ideal for water analysis, food control, and industrial applications involving sodium nitrate measurements.
