J157 PLUS HA Digital Refractometer perfect for High Accuracy measurements in the Sugar, Food & Beverage Industry
The Rudolph J157HA Digital Refractometer offers High Accuracy of RI ±0.00002, BRIX ±0.01 with a measurement range of RI 1.32 – 1.53, BRIX 0 – 100. Most importantly, this makes the J157HA an excellent choice for quality control of food and beverage products.
Digital Refractometer – J157 PLUS WR ideal for the Chemical Industry.
With a measurement range of RI 1.29 – 1.66 and BRIX 0 – 100 the Rudolph J157WR offer the versatility needed for Chemical plants where the chemicals are primarily non-water based. In addition, the J157WR offers accuracy of ±0.0001 RI and ±0.1 BRIX which is in excess of the accuracy required in most Chemical Plants.
J157-633 für Biotechnologie und biotechnologische Forschung
Ein Refraktometer für Biotechnologie und Bioengineering, das speziell für die Messung von Materialien in der optischen Wellenleiter-Lichtmodenspektroskopie entwickelt wurde (EULE) system thus capable of measuring the effective refractive index of a thin layer above an Si(Ti)O2 waveguide surface. The Digital J157-633 has all of the same features as the standard J157 automatic refractometer but operates at 633nm instead of the standard 589nm. The J157-633 is part of the Rudolph Research Refraktometer Produktlinie und weist viele der gleichen Merkmale wie unsere anderen Refraktometer auf.
Digital Refractometer – Includes the Rudolph PLUS Option
If you like or your application require some of the features of our higher end models you may add the J157 Plus option to either the HA or WR models. The Plus option adds the Smart Measure™ and Trend Analysis features that aid you in loading samples quickly and accurately. Rather than just choosing from the ever expanding range of custom scales provided by Rudolph the plus option lets users make their own. Simply measure 2 or more known points and the J157 plus has the ability to do the rest.
The temperature Control range is expanded to 10-85ºC and the Rudolph CC Temperature Sample Cover is added making the J157HA or J157WR an even more versatile refractometer.
Digital Refractometer Operation
Die Bedienung der J157 PLUS ist so einfach wie das Auflegen einer Probe auf das Prisma, das Schließen der Abdeckung und das Ablesen der Antwort - alles in nur wenigen Sekunden. Es gibt keine Schattenlinien, die übereinstimmen müssen, und es gibt kein Okular, das vom Bediener bestimmt oder manuell eingestellt werden muss, wie es bei Refraktometern vom Typ ABBE erforderlich ist. Wenn der Modus "Messen im stabilen Zustand" ausgewählt ist, wartet der J157 automatisch, bis die Probe elektronisch auf eine vordefinierte Temperatur erwärmt oder abgekühlt wurde, bevor eine Messung gestartet wird.
Duales elektronisches Temperaturkontrollsystem
Im Gegensatz zu anderen temperaturgesteuerten Refraktometern verfügt das J157 PLUS über eine elektronische Temperatursteuerung von oberhalb und unterhalb der Probe..
The sample cover is controlled to the same temperature as the prism and, when lowered, is designed to provide a temperature controlled micro-environment that provides unrivaled temperature stability, fast measurement time and minimal evaporation. Depending on options, the sample cover can also be used to initiate an automatic measurement.
Optionale Probenpresse
Das digitale Refraktometer J157 PLUS ist optional mit einem temperaturgesteuerten Probenandrücker erhältlich, der die Probe berührt. Verglichen mit der standardmäßigen temperaturgeregelten Abdeckung reduziert der optionale Drücker das leere Volumen des Messbereichs, wodurch die Verdunstung stark reduziert und gleichzeitig die gleichmäßige Verteilung vieler Arten von Materialien einschließlich halbfester Stoffe und Pasten über das Messprisma unterstützt wird. Diese Funktion bietet eine verbesserte Messleistung bei vielen Proben.

Digital Refractometer Auto Measure Option
Die Rudolph Auto Measure Option ermöglicht das Schließen und Öffnen des Drückers, um eine Messung zu starten und zu beenden. Der Bediener schließt einfach die Abdeckung, um die Messung zu starten, und hebt die Abdeckung an, um die Messung zu beenden. Das Schließen und Anheben des Deckels fungiert als Start/Stop im Messvorgang, ohne jemals die Messtaste zu berühren.
Easy to Clean Digital Refractometer Sample Well
Ganz gleich, wie groß das Refraktometer ist, genaue Ergebnisse werden nur dann erzielt, wenn das Prisma sauber ist. Alle Rudolph-Refraktometer der J-Serie bieten ein flaches, leicht zu reinigendes Prisma, das den Reinigungsprozess zwischen den Messungen selbst bei klebrigen Proben einfach macht.
Benutzerdefinierte Skalen
The J157 PLUS digital refractometer can be supplied with a large range of standard and customized scales. Scales can be customized in a few minutes. Simply enter 2, 6 or 10 points of concentration vs. corresponding RI data. The instrument calculates the custom scale automatically.
Digital Refractometer Calibration
The J157 PLUS Digital Refractometer offers 1 point, 2 point or a full multi-point calibration. Calibration can be done at 20°C, 25°C or any user selectable temperature within the available range. Regardless of how many times the refractometer has been calibrated, it can always be restored to the initial factory calibration if required.
Vom Benutzer konfigurierbar
Versatile laboratory instruments have the advantage of being able to display significant amounts of information. However this versatility can also lead to confusion, with extra buttons and by forcing operators to interpret extra results. These extra results that have no relevance to their application. Above all, the Rudolph J Series customizable display allows the refractometer to be configured to exactly what is required for each application.
The customizable digital keypad can be “locked out” or just a few keys can be operable. For example, the measure key, print key, zero key, customer specified sample keys or any combination thereof. In addition, the lockout function, calibration and other functions are all password protected.
Hochbeständiges Saphir-Prisma
The J series refractometers offer a sapphire prism for high mechanical and chemical durability. The sample well is made of acid resistant 316 stainless steel with a Techtron sealing ring. Most importantly, there is no lamp to change, the LED light source is guaranteed for 1,000,000 measurements.
Digital Refractometer – Three Displays Allow For Three Interface Solutions
Rudolph allows the lab manager to select from different display options. We understand laboratories and manufacturing floors have different needs when it comes to the information required for monitoring a process. Your instrument’s interface can be customized to meet the information your application and environment demand. You can choose our full featured interface or our Load-and-Go™ display interface. The J157 PLUS Digital Refractometer Series offer laboratory flexibility with industrial strength. Thus, this makes this model series at home on the laboratory bench or on the factory floor.
In a modern factory, the most precious commodity is time. When a process starts to move outside its limits people want to know FAST. They want to correct the problem, preferably while it’s still small and before a product goes out of specification. The Rudolph live reading and Trend Analysis™ feature allows users to easily and quickly see how a process is going. In addition, catching minor deviations before they become major ones. Even in the most tightly controlled manufacturing environments, things do occasionally go out of specification.
When an out of specification condition happens, material has to be quickly identified. In addition, decisions need to be made as to what to do with the product. Long term data collection is a part of any good process. Knowing when and where the out of specification condition happened is equally as important. Most importantly, Rudolph Trend Analysis™ software quickly shows a supervisor the process history and where the problem occurred.
Einfach und doch flexibel
Operating the J157 PLUS Digital Refractometer is simple. Simply place a sample on the prism, close the presser and read the answer. This can be done in a few short seconds. The entire keypad can be “locked out” or just a few keys can be operable. For example, the measure key, print key, zero key, customer specified sample keys or any combination thereof. In addition, the lockout function, like calibration and other functions are all password protected.
