PCE AdBlue refractometer PCE-DRU 1

Information on the AdBlue refractometer AdBlue, a mixture of distilled water and synthetic urea, is used in the automotive industry as a diesel additive. It is used to reduce nitrogen oxide emissions and to meet the legally prescribed exhaust emission standards. The digital AdBlue refractometer from PCE Instruments has been specially designed to perform a precise analysis of the urea solution. In this way, with the support of the AdBlue refractometer, the user can perform a straightforward quality control, check the urea concentration of the diesel additive AdBlue and determine whether the solution meets the requirements of the automotive industry.

The AdBlue refractometer is a precision measuring instrument based on the measurement of the refractive index of a liquid, guaranteeing maximum reliability even under difficult measuring conditions. Even with a small sample quantity, the user can measure the urea concentration in a liquid with the support of the AdBlue refractometer. To obtain a meaningful result, it is sufficient to drip a few drops of AdBlue into the stainless steel well of the measuring device. A prism is enclosed in the sample well, and the urea content is measured in this way by means of light refraction.

The integrated light source in the digital AdBlue refractometer prevents measurement errors that are quickly triggered by artificial light in an analog AdBlue refractometer. The temperature influence during the application is internally compensated by the measuring instrument. After this automatic temperature compensation (10 to 40 °C), the measurement result is displayed quickly and precisely on the large, easy-to-read LC display of the AdBlue refractometer. The user of the AdBlue refractometer can choose between two measuring parameters: Urea (NH2)/AdBlue (2CO) (0 to 51.0 %) and refractive index (1.3330 to 1.4056 nD). In addition, the display provides information about the measured temperature of the liquid thanks to an integrated temperature indicator. The glass prism of the digital AdBlue refractometer, which is enclosed in the stainless steel recess, can be cleaned quickly and easily before and after measurement and is closed with a plastic prism cover.

The manufacturer has designed the AdBlue refractometer to protect the glass prism from damage. The convenient three-button operation guarantees user-friendly operation. To conserve the meter’s battery, the manufacturer has equipped the digital AdBlue refractometer with an automatic switch-off function. When not in use, the AdBlue refractometer switches off automatically after one minute. A few drops of distilled water are sufficient to self-calibrate the AdBlue refractometer at the touch of a button, if required. Applications A refractometer is an optical measuring device that allows the user to determine the mixing ratio of numerous different solutions. The AdBlue refractometer from PCE Instruments is used in the automotive industry, is suitable for reliable instant analysis, is versatile and easy to use. During longer storage periods, the diesel additive AdBlue can gradually decompose. With the help of the digital AdBlue refractometer, the urea-water solution can be checked quickly and easily. Thanks to its user-friendly operation, the AdBlue refractometer is ideal for determining the urea content in AdBlue within seconds.

Thanks to its handy and robust design, the AdBlue refractometer can be used anytime and anywhere. Its simple operation and waterproof housing make the AdBlue refractometer irreplaceable when checking the diesel additive AdBlue and provide the user with important decision-making aids within seconds.
