I have the opertunity to buy this brand new from the "big auction site" for 31 bucks, I've never had one is it worth it?
One NEW RHS-10ATC dual scale portable Salinity Refractometer in a blue, foam-lined hard case. The RHS series of portable refractometers is designed to measure the salinity of sea water and saline solutions of similar concentration. One scale checks the NaCl levels with the range of 0-100 ppt (with 1 ppt scale divisions) and the other scale gauges Specific Gravity with a range of 1.000 to 1.070 (+/- 0.001 accuracy). Both enable the direct determination of salinity in water that contains dissolved salt and little or no other dissolved solids.
Hydrometers are nice, but they can be inaccurate, especially over time. The RHS-10ATC is designed to be very accurate to protect your investments!
All RHS models use ambient light, no battery or power source is required. Models with the “ATC” suffix are equipped with “Automatic Temperature Compensation” for accurate measurements without recalibration after shifts in ambient working temperature (field use).
Included are: a pipette for dropping test fluids onto the prism (never dip the refractometer into the test fluid!), a mini screwdriver for scale calibration, and a Users Guide.
