Red Sea Seawater RefractometerHigh Accuracy Seawater RefractometerRed Seaâ??s Seawater Refractometer offers exceptional accuracy, for measuring the absolute salinity of seawater at a temperature of 25oC/77 0F.Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums and use an algorithm for the measurement of brine (NaCl â?? rather than seawater) and at a temperature of 15oC/59 0F rather than 25oC/77 0F.Thus, a measurement deviation of up to 1.5ppt is possible, which can have a significant adverse effect on coral growth and coloration. Main features of Red Seaâ??s Seawater Refractometer include:Directly reads the absolutesalinity ofseawaterat25°C/77 0F ( No need for seawater or temperature compensation factors)Specifically designed for the ionic content of seawater (NSW) for more accurate salinity measurement (industry standard refractometers are calibrated for salt brine ).Calibrated for seawater (NSW) at 25oC/77oF, the norma

Features Largest Sharpest Display Scale Available Exclusive Zero-Ring Requires No Calibration Tools Durable, All-Metal Design VEE GEE X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution. Easy to Use. Operation consists of placing 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the readings. Accurate. Featuring the largest, easiest-to-read scale available with clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy even when several different operators use the instrument. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors. Compact Portable. The small size of the X-Series models allows them to be used anywhere the field, plant, or lab. Tool-Free Calibration. The VEE GEE exclusive Zero-Ring eliminates the hassle of using a separate tool for calibration. Simply place a few drops of distilled water or liquid standard (R.I. oil or prepared sucrose solution) on the prism, turn the built-in Zero-Ring until the shadow line is at the correct value of the liquid, and secure the set screw that's it Durable. The X-Series models feature rugged construction to provide years of reliable use. The prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Also feature non-roll stands to ensure that once the units are placed on a table or bench top, they won't be prone to roll off the surface. Wide Selection of Scales Ranges. Choose from Brix, Salinity, Refractive Index (nD), and Coolant (freezing points of Ethylene Propylene Glycol, Battery Charge Level), Urea and NaCI. Automatic Temperature Compensation (ATC). Models BTX-1, BTX-20, STX-3, CTX-1, CTX-2 feature ATC, which frees the user from havin

Brief Description Each gem has a typical refractive index due to its chemical composition and crystallization structure. The gem refractometer can be used to observe the optical properties and the structure of a gemstone. Through the parameters you can judge whether the gem is an anisotropic or isotropic stone. The stone needs a flat and polished facet. FULL SCALE Contact Liquid (RI Fluid) is also needed when testing. This Gem refractometer is a compact refractometer with built-in LED illumination for the determination of the refractive index (RI), quality and categories of gemstones.  Features Wide Measuring range: 1.30 ~ 1.81 RI High Accuracy: 0.01 RI Built-in LED illumination Polarizing filter  Specifications Accuracy: 0.01 RI Illumination: Built-in LED illumination with on/off switch Measuring range: 1.30 ~ 1.81 RI Scale division: 0.01 RI A bottle of 2 ml FULL SCALE refractive index (1.81 RI) oil (Not included) Filter: Polarizing filter Power source: 1 x CR2032 button cell battery (not included) Item size: approx. 30 x 70 x 130 mm Item weight: approx. 400g  One Set Included 1 x Gem Refractometer (main unit) 1 x instruction manua Carrying pouch
