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.
 

Measurement parameters:
- Salt content, chlorine content, refractive index,
  specific gravity, temperature
- Measurement range: 0 ... 100 ‰ salinity / 0 ... 57 ‰ chlorine 
- Resolution: 1 ‰ / 0.001 SG 
- Accuracy: ±2 ‰ / ±0.002 SG 
- Automatic temperature compensation (ATC)
