PCE Instruments DRS 2 Handheld Digital Refractometer for Salinity/Chlorine

Model # DRS 2

PCE-DRS 2 is a handheld digital sodium chloride (NaCl) and chlorine (Cl) refractometer used to determine the salinity or salt content (‰), chlorine content (‰), specific gravity (SG) and refractive index (nD) of liquid.
This waterproof IP65-rated digital refractometer features automatic temperature compensation (ATC) from +10 … +40 °C / +50 … +104 °F, as well as a large, easy-to-read LCD that shows both the measured value and the temperature.
Average function measures same sample 15 times and displays the mean value
ABS plastic housing with IP65 ingress protection rating against water and dust
