Universal refractometer QR,DH series

portable

Model QR-NaOH:For Sodium hydroxide QR-HSO:For Sulfuric acid DH-10C:For Battery specific gravity DH-10F:For Battery specific gravity Digital Suction-Type Refractometer QR-NaOH Special model for Sodium hydroxide Sodium hydroxide, also known as caustic soda or lye, is often prepared as solutions at different concentrations for a number of applications.The QR-NaOH allows the users to measure the concentrations without coming in contact with this alkali. Just plain tap water is sufficient for cleaning and zero-setting. Specifications Model:QR-NaOH Cat.No.:3354 Range:NaOH : 0.0 to 38.0% Temperature : 5 to 40°C Resolution:0.1% Accuracy:±0.2 % Temperature compensation:5 to 40°C Sample Volume:2mL Power Supply:006P alkaline battery (9V) Dimensions & Weight:7 × 4 × 21 cm, 300 g The length of nozzle: 13 cm Included Accessories:One 95 mm stainless pipe, one 95 mm silicon tube Digital Suction Type Refractometer QR-HSO Special model for Sulfuric acid This model is specifically designed for measuring sulfuric acid, which makes it ideal for a wide-range of applications in the industrial or pharmaceutical industries.The QR-HSO allows users to easily measure the concentration of sulfuric acid without coming in contact with this highly corrosive acid.Cleaning and zero-setting can be done with tap water. Specifications Model:QR-HSO Cat.No.:3355 Range:Sulfuric Acid : 0.0 to 35.0% Temperature : 5 to 40°C Resolution:0.1% Accuracy:±0.3 % Temperature compensation:5 to 40°C Sample Volume:2mL Power Supply:006P alkaline battery (9V) Dimensions & Weight:7 × 4 × 21 cm, 300 g The length of nozzle: 24 cm
