PCE-DRU 1 Handheld Digital Refractometer

The PCE-DRU 1 is a handheld digital refractometer specifically designed for measuring the urea concentration in AdBlue, a diesel exhaust fluid used in vehicles to reduce nitrogen oxide emissions. This device is notable for its digital functionality, providing fast and precise measurements with a user-friendly three-button operation. It features an IP65-rated ABS plastic housing, making it resistant to water and dust, and it includes automatic temperature compensation (ATC) to ensure accurate readings across different environments.

This refractometer can measure AdBlue content ranging from 0 to 51%, refractive index from 1.3330 to 1.4056 nD, and temperature from 0 to 40°C (32 to 104°F). Its measurement speed is approximately 1 second, requiring only 4 to 5 drops of liquid for a sample. The device’s large digital LCD displays both the measured value and the temperature for ease of reading. It’s equipped with an internal light source to enhance measurement accuracy, especially in conditions with artificial lighting that could potentially cause errors in analog refractometers.
