Vital Sine Refractometers

*	Largest and sharpest scale display we offer
*	Calibration ring allows very easy calibrations
*	Durable, all-metal design
*	Rubber hand grip eliminates transmission of hand heat to reduce errors

Features the largest, sharpest scale display for the most accurate salinity and specific gravity readings available (±1.0% salinity and ±0.001 specific gravity). Easy, no-tool calibration, with automatic compensation for shifts in ambient temperature (from 10°- 30°C). Compact and portable for use anywhere. Metal housing and rubber hood protect unit and prevent light from entering eyepiece. Features built-in calibration ring, no-roll stand, rubber grip to insulate against hand heat, storage case, instructions, and more. Range: 0 - 100 parts per thousand salinity, 1.000-1.070 specific gravity.

Pinpoint 53.0 µS Calibration/Reference Fluid sold separately.

Easy to Use
Operation consists of placing 1 to 2 drops of the sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the reading.

Accurate
Featuring the larges, easiest-read scale available with clear, sharp figures. These features significantly enhance the overall accuracy of our readouts - even when the instrument is used by several different operators. This model features a rubber grip on the body, which blocks the transmission of hand heat to reduce temperature errors.

Simple Calibration
The calibration ring eliminates the hassle of turning a calibration screw with a screwdriver while looking through the refractometer's eyepiece. Simply loosen the set screw, place a few drops of water on the prism, turn the built-in calibration ring until the shadowline is at zero, and secure the set screw - that's it.

Durable
Features a rugged construction for years of reliable use. The prism is mounted in all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Also features a non-roll stand to ensure that once the unit is set down, it won't be prone to roll off a table or benchtop.

pH and Koi Health

pH swings are very dangerous, as they interfere with basic body functions, leaving fish vulnerable to stress and disease. By educating yourself in the basics of water chemistry, you can help prevent disease and improve the health of your pond fish.

Optimize Your Pond

There are two ways to tell whether the oxygen level in your pond is sufficient: test and observation. Learn how to use these to provide your pond with the proper oxygen content.

Oxygen Breathes Life

Vital to its inhabitants, your pond water should always be near oxygen saturation. The key to maintaining sufficient oxygen in your pond is understanding its basic chemistry. Learn how to keep the oxygen levels in your pond at a healthy level.
