• Reduces harmful nitrogen oxide emissions from diesel engines. • Composed of 32.5% high-purity urea and 67.5% deionized water. • Clear, odorless and safe and easy to handle. • Inexpensive and efficient option for lowering NOx emissions. • Improves engine performance and fuel efficiency. • Includes: a firm plastic case, a refractometer ,a cleaning cloth, a screw driver, an operating instructions, some pipettes.
Aichose is a professional brand of supplying various kinds of liquids measuring instruments.
The refractometer series are based on the principle that the refractive indices of liquids change when the concentration change.
It's portable, easy, quick and no battery required, easier and more accurate than a traditional hydrymeters, more affordable than a digital meter.
It's a perfect tool for adult or young, home or professional use.
It features high-quality optics with smooth focusing. Its main body is made of aluminum alloy. The internal optical lens with high refractive index
make up the precision optical system.The instrument is resistant to abrasion and corrosion, can be used to measure the general corrosive liquid.
(But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )
