Guarantee 5015 Refractometer for Adblue Designed for checking the concentration of Adblue Adblue is the registered trademark for AUS32 (Aqueous Urea Solution 32.5%) and is used in a process called selective catalytic reduction (SCR) to reduce emissions of oxides of nitrogen from the exhaust of diesel engined motor vehicles. It is a 32.5% solution of high-purity urea in demineralised water that is clear, non- toxic and safe to handle. However, it can be corrosive for some metals and must be stored or transported using the correct materials. The Adblue trademark is currently held by the German Association of the Automobile Industry (VDA) who ensure quality standards are maintained in accordance with ISO 22241 specifi cations. Adblue

2 = Prism 3 = Calibration screw 4 = Mirror tube 5 = Eyepiece (focus adjustment) It is important to regulate the temperature of the sample, the instrument and the room as much as possible. Changes in temperature can affect the fi nal result. Temperature Specifi cation Measuring Range 0-40% Resolution 0.2 Measurements 27mm x 40mm x 160mm Weight 175g You may need to calibrate the instrument before use or after a rise or fall in temperature. 1. Open the cover plate (2). 2. Drop 1/2 drops of distilled water onto the prism (1). 3. Adjust the meter to zero (0). 4. Close the cover plate (2) and press gently. 5. Rotate and adjust the calibration screw (3) until the light blue boundary line meets the zero (0) line. Calibration 1. Take a sample of the Adblue mixture 2. Place a droplet on the prism and cover 3. Look through the eye-piece 4. Adjust the light if necessary to focus the line between the dark and light areas. 5. Line this up with the marked measurement scale 6. Take the reading Measurement • Use only soft tissue or cloth to clean the prism as it is very easily scratched. • Dab away the sample and then use distilled water or a glass-safe solvent such as alcohol to clean the prism. Cleaning • Adjustment for the distilled water and sample should be in the same temperature. • Once the temperature changes, the zero (0) point should be adjusted once per 30 seconds. • Do not immerse in water • This is a precision optical instrument and should be handles gently • Do not touch or scratch the optical surface. • Please keep it in a dry, clean and non- corrosiveness environment • Avoid dropping Attention and Maintenance 1 2 3 4 5 0 0 5 5 10 10 15 15 20 20 25 25 30 30 35 35 40 40 AUS 32 20°C [68°F] 0 0 5 5 10 10 15 15 20 20 25 25 30 30 35 35 40 40 AUS 32 20°C [68°F] Calibration with distilled water
