Features:

• It is more accurate than a hydrometer and easy to measure. Designed for the testing the concentration of salt water and brine, perfect for use with aquarium Marine monitoring and quality control in scientific research and clinical laboratories
• Measurement range: Salinity 0 - 100 ppt, (0 - 10% salt content), SG 1.000 to 1.070 SG, Resolution: Salinity +/-1 ppt; +/-0.001 SG
• Easy to use. Place 2 drops sample on the main Prism and close the panel and hold the refractometer up to the light and look through the eyepiece.
• The refractometer's body and the retaining ring are made of brass and chrome plated. The internal optical lens with high refractive index make up the precision optical system.

Details:

Technical Description: The product is designed for testing the concentration of salt water and brine. Provides a direct reading of the specific weight and concentration (Part per thousand) of salt in water. It gives you reliable refractive index and Salinity values of the dissolved solids of watery solutions. It is used for by our quality control in research and clinical laboratories.

It can be used to check stem solutions and thinners and to hold. In the food industry it is particularly effective on the preparation of frozen vegetables, fruits, sea fruits and ocean by-products. The Salinity Refractometer is also available in ocean ographie and saltwater studies for determining the soil quality. The model with ATC (Automatic Temperature Compensation) is ideal for general use in the field.

Compensation temperature range: 50℉-86℉ Calibration: Zero calibration with water close to 68 ℉. Specification: Material:The metal part is made of brass chrome. Quantity: 1pcs Color: As shown Measure Range: 0-100ppt(0-10%); Min:1ppt Salinity Proportion: 1.000-1.070sg; Min:0.001 Size: 4*20cm / 2.1*0.9*0.9" (D*H) Package: 1 x Refractometer 4 x Plastic Pipette 1 x Mini Screw Driver 1 x User Manual 1 x Cleaning Cloth 1 x Storage Bag
