With a built-in LED light this Refractometer can be used in complete darkness but will also help in low light - hard to read areas too!  No mare searching for strong light to read your refract!

Details:

These tools are used to measure how much salt is in our water.  Having a stable salinity is critical & the tool we use to measure it is probably one of the most important we'll buy for our hobby.  We need to keep the salt level within a healthy range 1.026 is my recommendation & most salt mixes are calibrated for.  Our salinity is critical to all reef life and needs to be kept consistent - no swings up or down.  Cheap plastic hydrometers will give false readings many times right out of the package & most certainly over time as the "swing arm" gets weighted down with minerals.  This would allow one to believe their salinity is fine when in fact, it's much higher!  This is why I don't sell hydrometers.  Don't risk the health of your entire livestock population!  Invest in a good quality, simple to use refractometer & rest assured you're getting a true reading!

The RHS-10ATC dual scale portable Salinity Refractometer in a Gray 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 Salinity 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!

The unit comes with the "ATC" suffix which is equipped with "Automatic Temperature Compensation" for accurate measurements without recalibration after shifts in ambient working temperature (field use). The ambient temp range for ATC is 50-86'F (10-30'C). If the temp is outside the range (warmer for example), the readings will become gradually inaccurate the further the temp is away from the 50-86'F range.

Easy to calibrate:

I like using RO water.  It should read Zero on the bottom right of the graph.

Alternative Calibration using optional Salinity Fluid!

How to calibrate with Salinity Fluid: Take a couple drops and read your unit. You should read 1.0259 salinity or 35ppt. Adjust your unit to match one of these two numbers. Once you adjusted the refractometer is now fine tuned for saltwater salinity/ppt. If you read ro/di after calibration you will have a negative reading and that is completely normal, as the unit is fine tuned now for a saltwater tank.

 

How To Use: (always read the left SG):

Remember - 1.026 is the best level to run a reef tank.  The chart below shows 1.024 - a bit too low.

Again, I use RO water.  You want it to read Zero on the bottom of the right side graph.  If it doesn't, use the provided screw driver, pop off the rubber cap to the adjustment screw & with the screwdriver turn slightly to make the line go up or down to make it read on zero.  Remember to adjust the eye piece so you can see the line clearly.  The eye piece adjusts like binoculars.

Note:  There may be slight differences in the color of components like the cloth color etc.
