Manufacturer: Aqua Medic

The Aqua Medic Refractometer is a precision optical instrument used to determine the salt concentration in saltwater aquaria. The exact value can be determined in seconds and can be read either as absolute salt concentration or as specific density. Refractometers are non-electrical devices that work by measuring the refraction of light through an aquarium water sample on a glass plate. A screw driver for calibration is included

The VEE GEE CTX-1 is a handheld, portable, water-resistant antifreeze and battery charge level refractometer that measures the freezing point of propylene glycol in the -50.0 to 0.0 degrees C range, freezing point of ethylene glycol in the -50.0 to 0.0 degrees C range, and the specific gravity (SG) of battery acid in the 1.10 to 1.40 range, has automatic temperature compensation (ATC), and a durable metal body with rubber grip. Handheld refractometers, also known as sugar meters, concentration meters, or Brix meters, are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications. This refractometer is housed in a durable metal body. The VEE GEE CTX-1 features ATC for immediate, accurate readings, with an ambient temperature of 10 to 30 degrees C. The unit is factory-calibrated and can be calibrated with distilled water. Calibration can be controlled and adjusted with a tool-free calibration ring and a set screw. The outer shell is rubber coated with dimpled grip for easy gripping and the rubber coating guards against hand heat for accurate measurements. A non-roll stand prevents the unit from rolling when placed on a flat surface such as a table or bench top. The optical glass prism is mounted in an all-metal housing composed of copper alloy with a nickel-chrome coating for quick temperature equilibrium between the sample and the prism. The analog Brix scale features a bright, high-contrast display for clear visibility of the boundary and memory lines intersection. Instantaneous sample readings illuminated by ambient light are viewed through a monocular, focusable, cushioned eyepiece. The unit comes with a zippered vinyl carrying case, a plastic transfer pipet and an instruction manual. Specifications Measurement scale range Freezing point of propylene glycol -50.0 to 0.0 degrees C, Freezing point of ethylene glycol -50.0 to 0.0 degrees C, Specific Gravity (SG) of battery acid 1.10 to 1.40 Specimen...

Hand refractometers are made with a variety of different scales to measure dissolved solids in solution. The various hand refractometers are categorized according to the type of measurement scale required. All are easily transportable for field use, simple to use, and require only an outside light source to be functional. Models with the ATC designation are Automatic Temperature Compensated over a 40º F temperature range.  Brix scale hand refractometers are developed for sugar-related liquids such as fruit juices, honey, soft drinks, and wines. These units are used to help monitor and control the sugar concentrations of products in the food and beverage industry. Whether checking the "ripeness" of fruit in the field, verifying product quality after the harvest, or controlling concentrations during processing and packaging, refractometers provide critical information to ensure product quality. Full ranges of measurement are available.

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

BX-50 Handheld Refractometer, 0-50% Brix VEE GEE X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution. Includes Carry Case (1 ea.) Plastic Transfer Pipet (1 ea.) Instruction Manual (1 ea.) Features Largest Sharpest Display Scale Available Exclusive Zero-Ring Requires No Calibration Tools Durable, All-Metal Design 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.
