About this item

• ✅【What is AUS32/DEF Refratometer】The DEF refractometer is a kind of portable precision optical instrument, which is designed to measure the concentration of the diesel exhaust fluid.
• ✅ 【Easy to Operate】Only 3 steps to know your DEF condition in a quick and easy way: calibrate the refractometer to 0, then place a liquid sample to be tested on the main prism and close the light plate, finally check the readings through the eyepiece under light source.
• ✅ 【Automatic Temperature Compensation (ATC)】An automatic temperature compensation range from 10~30℃ will make result more accurate. As long as the ambient temperature of prism does not change, the sample size is so small that it will quickly come to the same temperature as the refractometer. If ambient temperature changes significantly then you will need to rezero the refractometer with water.
• ✅【Optical Theory of the Refratometer】Drip 2-3 drops of liquid sample on the prism, you can get accurate readings. The light passing through it is bent, and the more concentrated the liquid the more the light will bend.
