Handheld urea concentration meter is mainly used for rapid detection of various types of automotive urea solution product concentration, can be very convenient to help car manufacturers, bus companies, large fleet and other end users to detect vehicle urea solution product concentration is qualified.
Diesel engine exhaust treatment fluid (commonly known as: automotive urea, automotive urea, automotive environmental protection urea), SCR technology must be used in the consumables.
Diesel engine exhaust gas purification agent is the main component of urea solution, which is to eliminate the exhaust gas nitrogen oxides in a reducing agent, through the conversion of the catalyst to nitrogen oxides reduced to non-polluting nitrogen and water vapor, to the exhaust emission standards.
Automotive urea solution is the most basic function of the car exhaust nitrogen oxides into harmless nitrogen and water, energy saving and environmental protection so that your car to meet the national requirements of the exhaust emission standards.
The vehicle urea solution (AUS 32) is a solution prepared with industrial pure urea and pure water without any other additives. Most domestic and foreign heavy duty diesel engine manufacturers use SCR (selective catalytic reduction) technology to meet the country IV machine EMU emission standards.
SCR technology is added in the hot exhaust for the car to use the vehicle urea solution (product called AdBlue), urea solution in the subsequent SCR catalyst with nitrogen oxides, so that it into nitrogen and water vapor.
The urea content directly affects the catalytic efficiency of NOx and the freezing point of urea solution. In the SCR reduction system, the concentration of urea solution is one of the key factors, too high or too low concentration not only can not improve the efficiency of NOx conversion, but will cause the loss of ammonia (due to excessive NH3 / NOx ratio caused Ammonia leak), the formation of secondary pollutants ammonia.
The use of urea solution catalytic reduction is an effective means of controlling the exhaust emissions of diesel vehicles. Only to the urea solution specifications and test methods to be strictly regulated in order to ensure that the diesel engine exhaust gas purification effect, to prevent unacceptable urea solution to bring new pollution to the urban atmospheric environment adversely affected.
For the majority of users, depots, large customers to buy qualified vehicle urea products, the company has developed a convenient vehicle urea solution concentration detection equipment. The instrument can quickly detect the concentration of vehicle urea solution is a tool for the convenience of automobile manufacturers, end-user technology, quality department, antifreeze, vehicle urea solution dealers to quickly identify some of the indicators of the product.
1, not in the relative humidity of more than 85% of the ring mirror in the long-term placement, so as not to affect the optical system.
2, do not get into the liquid and water adjustment knob and eyepiece, so as not to damage the internal components.
3, do not leap and collision, so as not to damage the instrument accuracy.
4, immediately after use with a clean cloth to the prism and the refractive plate wipe light net.
First, the principle: The basic principle is to use the total reflection critical angle method to measure the refractive index of the solution, and then calibrate the measured liquid concentration and its performance. Because of its principle of reliable, accurate to meet the actual needs, there are small size, light weight, handsome in appearance, easy to use, it is widely used in the automotive industry.
