Heavy Duty Refractometer



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 1.023 - 1.026 (1.026 is best for reef tanks) and we need to keep it 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!

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.
