With our refractometer TMT-RHA-503abATC you can determine the concentration of urea in AdBlue. What is AdBlue? AdBlue is an aqueous colorless urea solution with 32.5 percent pure urea and 67.5 percent deionized water. The liquid is used in the automobile industry. Long periods of storage procure a creeping of the liquid. The device is suitable for checking the urea-water solution during delivery, storage or in customer cars. The device provides with its integrated automatic temperature compensation system (ATC) a high degree of precision and ease of use. The hand refractometer is equipped with a stable metal case and a plastic handle.

Example measurement:
Before each measuring procedure you should clean the lift-up lid and the prism carefully and afterwards dry to leave. Then you give 1-2 drops of the sample on the prism, when closing the lift-up lid the sample distributes itself evenly between covers and prism. Pay attention that no air vesicles form. This would impair the fair result negatively. By easy moving of the lift-up lid the sample liquid can be distributed evenly. Now you hold the refractometer against bright daylight, in order to see the scale by the eyepiece. The desired value can be read off now directly. Please carefully clean and dry the equipment after each measuring procedure, so that no deposits are left on the prism and the cover.
