The Kern ORA 1UA is a manual analogue refractometer designed for professionals who need to accurately measure the concentration of urea solutions, such as AdBlue. Its key benefit is providing direct readings without complex calculations, thanks to built-in, precisely calibrated scales, ensuring efficient and repeatable measurements in production environments. However, as an analogue device, it requires manual reading and interpretation.

The Kern ORA 1UA is primarily used to measure the concentration of urea solutions, such as AdBlue, in the range of 0-40%.
No, the Kern ORA 1UA is an analogue manual refractometer and does not require batteries.
ATC automatically adjusts the reading based on the ambient temperature, ensuring accurate measurements without manual temperature correction across a typical range of environmental conditions.
The ORA 1UA typically comes with calibration liquid, a calibration block, a storage box, a pipette, a small screwdriver, and a cleaning tissue.
The ORA 1UA is specifically calibrated for urea solutions. For sugar solutions, you would need a model with Brix scales, such as the Kern ORA 32BA.
It is recommended to calibrate the refractometer before first use and periodically thereafter, especially if accuracy is critical or after potential impacts or significant temperature changes.
The instrument is designed for industrial use but is not fully waterproof. Care should be taken to avoid submersion or excessive water exposure. Clean with a damp cloth.
Adjust the focus by rotating the eyepiece until the scale appears sharp.
Ensure the prism and cover plate are clean. Verify sufficient sample is applied and no air bubbles are present. Check ambient temperature and allow the instrument to acclimate if significant changes have occurred. Recalibrate if necessary.
Ensure the instrument is pointed towards a good light source. Clean the eyepiece if it is smudged.
Inspect for physical damage. If significant damage is present, discontinue use and contact the manufacturer or supplier for repair or replacement options.
