Description

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) Customer Reviews Write a review 7 of 7 people found the following review helpful: Excellent! Nice instrument by Connie Experience Level: Beginner Posted on 8/12/2007 from ROYAL PALM BEACH, FL UNITED ST Comments: I am new to this hobby. I tried this instrument and a Hydrometer to see which one was easier to use and more accurate. Both gave me the same readings, but this little gem is far easier to use. I love it and I would purchase it again. Yes, I would recommend this product to my friends. Was this review helpful to you?         6 of 6 people found the following review helpful: Excellent!
