The Captive Purity Refractometer is an incredibly accurate and easy to use device that eliminates the confusion associated with inexpensive hydrometers. Just place a couple of drops of water on the prism and hold to the light. Reads in percent and specific gravity. An absolute must for the serious marine hobbyist.

The Captive Purity Refractometer is an optical device (no batteries) dual scaled 0-100% specific gravity: 1.0 to 1.070. Calibrate with distilled water. Adjustable eyepiece, carrying case, pipette and calibration screw driver included. This model is ATC (automatic temperature compensating)

GREAT by BRANDON STARKEL

Experience Level: Intermediate

Posted on 1/31/2008 from RONAN, MT UNITED STATES

Comments: Well I waited way to long to make this purchase. I had been using a eight dollar cheapo . Calibration was a piece of cake. Easy to use as well. The brighter the light the easier to read.
Yes, I would recommend this product to my friends.

Excellent!

Simplistic by KAJ

Comments: I was using the coralife deepsix, and I thought I was at 35PPT, but after going to a LFS, they told me I was at 45PPT. The accuracy, ease of use, makes this an item that all reefers should have.
Yes, I would recommend this product to my friends.
