KERN analog refractometer ORA-P (urine)
The KERN Analog Refractometer ORA-P (Urine) provides specialist users in clinics, laboratories and veterinary facilities with a reliable solution for precise urine analysis. Thanks to its robust design and specially manufactured optical materials, this model offers accurate measurements even under demanding environmental conditions. Compared to similarly constructed products such as the KERN Analog Refractometer ORA-S, it scores points above all for its user-friendly operation and wide range of applications for medical controls. Consistent measurement accuracy is essential, especially in hospitals or research facilities - professionals place particular value on reliable results and ease of use.
Variety of applications and advantages
The use of this refractometer makes it possible to determine the refractive index, specific urine weight and serum protein content quickly and accurately. The device is easy to hold and, depending on the version, has automatic temperature compensation (ATC), which ensures reliably consistent results, especially in changing environments. Practical accessories such as a pipette and calibration solution are included so that users can start taking accurate measurements straight away. The KERN analog refractometer ORA-R, which is particularly suitable for other liquids, can be used as a further alternative with other measuring ranges.
Technical features
The most important technical features are clearly structured scales, precise graduations and - in the ATC models - reliable compensation for ambient temperatures. Depending on the model, different measuring ranges are available, tailored to specific requirements:
- Refractive index (1.3330-1.3600 nD with 0.0005 nD as graduation)
- Urine (specific gravity 1.000-1.050 sgU or 1.000-1.060 sgU, depending on the model)
- Serum proteins (0-12 g/dl, division 0.2 g/dl or 2-14 g/dl, division 0.1 g/dl)
- Automatic temperature compensation (for models with "ATC")
- Robust housing design for mobile use
- Adjustable eyepiece for individual visual acuity
The ORA 2PB, ORA 2PA and ORA 5PB variants each have a different focus: ORA 2PB and ORA 2PA focus on standard urine tests in humans, while ORA 5PB, with an extended measuring range of 1,000-1,060 sgU, is designed specifically for veterinarians (cat/dog). The versions with ATC (e.g. ORA 2PA) ensure that measurement deviations due to temperature differences are minimized.
Certifications and standards
All models are manufactured in accordance with current quality and safety standards and therefore meet the high requirements of the medical sector. When used correctly and calibrated regularly, they guarantee stable measured values that are approved for documentation in many countries. Similar standards apply for veterinary applications as for products required in veterinary practices, so that a professional and standard-compliant diagnosis is always possible.
Concrete application examples
- Monitoring kidney function in hospitals by measuring the specific urine weight and serum protein content
.
- Regular diagnostics in doctors' surgeries to detect signs of dehydration, infections or other disorders
- Sports medicine examinations, in particular doping tests, in which urine samples are tested for certain markers.
- Veterinarians use the device for routine examinations of dogs and cats, for example to determine the correct treatment strategy for kidney disease.
- In retirement and nursing homes, a quick urinalysis can provide valuable information on the health of residents.
- Schools or medical training institutions use reliable handheld refractometers to teach practical skills.
FAQs
How to calibrate the device
Take the calibration solution supplied and apply a few drops to the prism. Then adjust with the screwdriver if necessary until the displayed measured value corresponds exactly to the reference value.
Do you need any special prior knowledge for measurements?
Basic knowledge of refractometry is helpful, but the clear scale display and easily adjustable eyepiece mean that even beginners can use the device safely.
What is ATC?
ATC stands for "Automatic Temperature Compensation". This function ensures that temperature fluctuations in the laboratory or examination room do not affect the measured value, which increases accuracy.
Can other liquids also be measured with the refractometer?
In principle, it is designed for urine analysis. However, other aqueous samples with a similar refractive index can also be measured. For significantly different liquids, a model with a suitable measuring range is recommended.
How to clean the device
After each use, it is sufficient to carefully clean the prism and the cover with a soft, lint-free cloth. For heavier soiling, you can use a mild cleaning fluid and then rinse the device with clear water.
Conclusion
This refractometer impresses with its versatility and precision for daily urine analysis in the medical and veterinary fields. Thanks to the clear scales and optional temperature compensation (ATC), accurate measurement is guaranteed even under variable conditions. All this makes the KERN analog refractometer ORA-P (urine) a powerful choice for professionals who do not want to compromise on their urine tests.
