Manufacturer: Grand Index Brand: Grand Index Model: P-RHS-10ATC Color: Blue Rubber

Specifications: Minimum Division: Salinity: 0.1% Refractive Index: 0.001 (ATC) Temperature Compensation Range:10°C--30°C Determines the amount of dissolved salt and dissolved solids Approved by strict quality and safety standards Durable and built to last long Accurate testing results guaranteed Cushioned with soft & comfortable non-slip rubber Extremely easy-to-use and calibrate Salinity Refractometer is designed for testing the concentration of salt water and brine and used for quality control in research and clinical laboratories and marine industry. Its scale provides a direct reading of the specific gravity and concentration (part per Thousand) of salt in water. One scale checks the NaCl levels with the range of 0-100 ppt (with 1 ppt scale divisions) and the other scale gauges Specific Gravity with a range of 1.000 to 1.070 (±0.001 accuracy). Both enables the direct determination of salinity in water that contains dissolved salt and little or no other dissolved solids. It is suitable for a marine saltwater tank. It's FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down! Plus an option to get an extra 50pcs of transfer pipettes in 1ml and/or 3ml, a bottle of dioptic oil (calibration oil) and a reference block just by adding a small amount to your order, see Available Options below .

Manufacturer: PYRUS Brand: PYRUS

Features: Digital-display refractometers are used exclusively for liquids, and digital handheld models provide a digital readout. Analog handheld refractometer readings are obtained by looking through the monocular eyepiece and viewing where the boundary line intersects with the memory line. Handheld portable refractometer for measurement of salt concentration in parts per thousand (PPT) (0 to 100%) and specific gravity (SG) (1.000 to 1.070) of seawater in the 10 to 30 degrees C temperature range. Notice: Don't directly into the water to wash after measurement. Don't measure abrasive or corrosive chemicals with this instrument. They can damage the prism's coating. Directly use the damp cloth to clean the surface of the prism and the cover, to be dried and properly stored. The instrument should be placed in a dry, non-corrosive gases place of custody, and to avoid the loss of spare parts. Specification: Materials: Aluminum Alloy + Rubber Color: Black Size: 7.5 x 1.2 inch (19 x 3 cm) Measure Range: 0-100%(0-10%) Accuracy: 0.001sg(1%) Salinity Proportion: 1.000-1.070sg Package Include: 1 x PYRUS Salinity Refract meter 1 x Carrying Case 1 x Plastic Transfer Pipet 1 x Instructions

Manufacturer: Amzdeal Brand: Amzdeal

IntroductionThis Amzdeal dual scale salinity refractometer is used to measure, monitor and control the concentration of salt water and brine, especially useful for aquarium and marine applications. This high quality refractometer measures on 2 scales, Specific Gravity (D 20/20) and parts per thousand and replaces your poor quality and difficult to read hydrometer. With just a couple of drops of aquarium water you know exactly what your salinity is. Specification Model : ATC Refractometer Material : Aluminum alloy + plastic + optical lens Measuring range: Salt content 0 ~ 100 ‰ (0 ~ 10%) / Salt specific gravity 1.000 ~ 1.070sg Minimum scale: Salt content 1 ‰ (0.1%) / Salt specific gravity 0.001sg Working Temperature : 5-30 ℃ / 41-86℉ Package Content 1 x Salinity Refractometer 1 x Dropper 1 x Screwdriver 1 x Cleaning Cloth 1 x Case 1 x User Manual Using Step -Calibration 1. Open the cover, drop 3-4 drops of distilled water to the prism. 2. Look into the eyepiece to see if the line between blue and white is at "0". If not, adjust the calibration screw using the screwdriver until the line is at "0". 3. Use the cloth to wipe the water. -Measuring 1. Drop 3-4 drops of sea water to the prism, making sure that no bubbles. 2.Look into the eyepiece to read the number the line between blue and white at. And this is the salt content .
