A.KRÜSS Optronic Digital Hand-held Refractometers
For mobile use with a large measurement range!
Quick, precise measurement results simplify incoming goods inspection, optimise quality assurance and reduce work processes. The devices can easily be carried on inspection rounds, as they are lightweight and fit into any lab coat pocket.
DR101-60 und DR101-60-OE
As an entry-level model in digital refractometry, the DR101-60 covers many areas of application where the wide measurement range of the DR201-95 is not required. It offers excellent value for money, in terms of both procurement and operation. Calibration is also with distilled water. The waterproof case allows the DR101-60 to be rinsed under running water. This digital handheld refractometer also has an automatic temperature compensation feature, of course.
DR201-95 and DR201-95-OE
The DR201-95 is a compact digital handheld refractometer which eliminates any user-related reading errors of manual handheld refractometers. Specially developed for fast and easy quality control and process control, it has a wide measuring range for a refractive index scale and a sugar scale. One DR201-95 can thus often replace several existing instruments. For wine-growing, a special model is available with an Oechsle scale instead of a sugar scale. Both instruments are low-maintenance and are calibrated simply with distilled water. The 1.5 V battery lasts for over 1000 measurements.
DR301-95
The digital handheld refractometer DR301-95 has more functions than a simple handheld refractometer and at the same time is more cost-effective than a desktop unit. Besides the refractive index, sugar and salt scales, up to two other user-defined scales can be programmed. To do this, the handheld refractometer can be connected to a PC via a serial interface. The software supplied with it allows results to be managed and printed out. While the instrument can be operated as a mobile unit with a 9 V block battery, the optionally available power supply unit turns the DR301-95 into a small laboratory refractometer. The sample plate is made of stainless steel and is so flat that it can be cleaned quickly and easily. The instrument is calibrated simply with distilled water and has an optional temperature compensation feature. For incoming goods control applications, an upper and lower tolerance alarm can be entered.

Q: Saves time
A: This reason might be the most obvious, but it’s a clear benefit of an FAQ page. Not only does the FAQ page save customers time, but it also saves employees time as well. Having an FAQ page ensures customers don’t have to sit on the phone for hours waiting for simple answers, and employees don’t have to individually answer all questions.
Q: Earns trust
A: Information is available at the click of a button, but as we all know, information is not always true. Because of this, customers are more skeptical than ever before. They hunt for products by sifting through reviews, looking at the product on multiple websites, and doing price checking across the internet.
Q: Provides new insights
A: It’s difficult to get into the head of a shopper. Some buy on impulse, and others buy after thorough research. By tracking the clicks on your FAQ page, you can gather insights about your product or service that you didn’t know before. You can then inform your product team of these insights. From there, the product team can make changes to improve the product or experience.
Q: Drives internal page views
A: If you want your FAQ to be extremely thorough, which it should be, you can link to resources within your FAQ for your customers to find out more information. Whether you link to a blog that goes into more detail or a product page, this content helps the shoppers get the full story before making a purchase.
A: Prevents negative reviews
A: When looking through negative reviews, there’s almost always one thing in common: the problem could’ve been avoided.
