Designed for checking the concentration of AdBlue®. AdBlue® is a urea additive in the exhaust flow, which reduces NOx- emissions in HGVs and Light Commercials. This refractometer can check the concentration of AdBlue® with just a small amount of fluid.
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 final result.
You may need to calibrate the instrument before use or after a rise or fall in temperature.
