JBJ C-Scope Refractometer w/ ATC
The JBJ C-Scope Refractometer w/ ATC is designed for testing the concentrations of saltwater by providing a direct reading of the speciific gravity and salinity in ppt. It provides a reliable refractive index and salinity readings of total dissolved solids of aqueous solutions. The refractive index is the ratio of the the speed of light in a vacuum to the speed of light in the medium (saltwater) being measured. Light is slowed by passing through saltwater, so the index of the refraction is an indication of this speed change.
You simply add a few drops of your saltwater water over the prism and focus the eyepiece under direct lighting until you see a line that divides the scale from blue and white. This line indicates the specific gravity and the salinity.
- Magnified Dual Scale. This simple integrated feature magnifies the scale over 2x compared to traditional refractometers for easy viewing.
- ATC - Automatic Temperature Compensation. Since water temperature effects salt readings, all C-scope refractometers are equipped with ATC to give the correct reading even if your water temperature isn’t.
- Quick Calibration. The ability to calibrate the refractometer allows you to cross reference your readings without ever have to second guess yourself.
- Deep Color Contrast. The C-Scope was designed to provide a clear and sharp dual scale. This is accomplished with a deep color contrast between the blue and white to quickly distinguish your measurement.
