Salinity Refractometer - 0 to 100 PPT with ATC

This Salinity Refractometer provides precise measurements of salt levels using specific gravity (SG) for Seawater and Salt Water Aquariums.  Automatic Temperature Compensation (ATC) is perfect for field use as it compensates its readings according to temperature.  The Salinity Tester can be used in oceanography and seawater studies for determining water quality. It provides reliable refractive index and salinity readings of total dissolved solids of aqueous solutions. It is used for quality control in research and laboratories. This is a quality optical instrument that includes a soft carrying case, bulb filler, screwdriver and instructions. Soft rubber eye piece for comfortable viewing Comfortable non-slip rubber grip Measurement scale provides direct reading Accurate testing results Extremely easy to use and calibrate Durable and built to last Adjustable manual focus No battery or power source required *Certification Option Certificate of Calibration available at additional cost (Select option above).
