Salinity Refractometer RES-10ATC | 0 to 10% | 1.000 to 1.070 SG | ATC

The RES-10ATC is a handheld optical salinity refractometer with two scales, 0 to 10% salinity and 1.000 to 1.070g/cm3 specific gravity, plus automatic temperature compensation from 10 to 30°C. You place a drop of seawater or a weak salt solution on the prism, look through the eyepiece and read the result from a clear scale, so there are no batteries to check. Features and benefits: - Dual scale reading - salinity in % (0 to 100ppt salt) and specific gravity (density) on one view, with resolution of 1ppt and 0.001g/cm3. - Automatic temperature compensation from 10 to 30°C - readings stay steady when the room or tank water is not exactly at the 20°C scale reference temperature. - Adjustable focus eyepiece - sharpen the scale line to suit your eyesight. - Adjustment screw - set the zero point on fresh water, and for tighter work check once against a solution matching 35ppt seawater. - Aluminium and rubber body with a non-slip rubberised grip - a firm hold, and the grip keeps the sample away from hand warmth. - Soft rubber eyepiece - comfortable to use for repeated checks. - Case, sample pipettes, cloth and a small screwdriver supplied - ready to use out of the box. Applications: - Checking the salinity of marine aquarium and reef tank water - Measuring brine and other weakly concentrated salt solutions in the workshop - Routine salt water checks in school and training labs - Quality control checks on saline solutions In the box: The refractometer itself, an English instruction manual, a mini screwdriver, two pipettes, a cleaning cloth and a protective carrying case. Note: Made for seawater and low concentration salt solutions only, with a top reading of 10% salinity. Set the zero before use, wipe the prism clean after every sample and do not scratch it.
