For determining the concentration of oil in water emulsions and transparent solutions, such as machine shop coolant. Maintaining the correct mixture in coolant systems is vital to ensure optimum performance from cutting tools. To protect the machine and workpiece from corrosion and to reduce the risk of health hazards arising from incorrect concentrations of water soluble oils. To economise the use of water base cutting fluids and grinding fluids. Specifications: range ND: 1.333 -1.356 Bx:0 - 15%. Eyepiece magnification: x11. Telescopic lens magnification: x4.

well it gives you your salt level ok so i would thinks so it must be worth the money

 

[bae1994]

yeah but the scale starts at 1.333

You need a scale that is going to cover the range of sg you are working with. We keep reef tanks around 1.025-1.026, therefore you need a refractometer that has this scale somewhere around the middle. Will have a look at the range on mine in a bit and post it for you.

It is a good bit of kit, just the wrong application. Can you return it??

I have the D-D refractometer, tthe scale on mine goes from 1.000 - 1.070 d20/20 0/00 Salinity (shown when you look into the display.

Yours appears to be very precise as the scale is a very narrow range, however it is not made for the application you want it for.
