refractometer?

Leprichon

Im in the market for a refractometer...Im not as concerned with price (at the moment) as I am with ease of use and accuracy...ive done a little research and think I know what Im looking for:

• a portable refractometer (not a hygrometer)(with about 0-100 ppt salinity and 1.000-1.070 specific gravity
• a unit with ATC (autimatic temp compensation) to composite for changes in the temperature of the room when testing…

· a unit where initial Calibration can be done at any room tempature.

· a unit that stays calibrated (so that you don’t have to calibrate it EVERYTIME you use it)

· a unit with its own backlight

· unit with an adjustable eyepiece, insulated body to reduce thermal influence on test

· unit with good optics. (not one with a small display or one with scale numbers that are too small.

· Get one that stores securely in its own case.



....but Id love any opinions and/or suggestions...

most decent quality commercial refractometers range between 50-60 upwards of 100 dollars. all of those have what you need, minus the backlight -- backlit refractometers are non existent from what i understand. good luck!

use the sun, or a flash light -- not that bad.
