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 para la investigación en biotecnología y bioingeniería
Un refractómetro de biotecnología y bioingeniería diseñado específicamente para medir los materiales en la espectroscopia de modo de luz de guía de ondas ópticas (OWLS) 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 Refractómetro y comparte muchas de las mismas características que nuestros otros refractómetros.
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
Operar el J157 PLUS es tan simple como colocar una muestra en el prisma, cerrar la tapa y leer la respuesta, todo en unos pocos segundos. No hay líneas de sombra que coincidan y no hay oculares que requieran ningún tipo de determinación por parte del operador o ajuste manual como es necesario con los refractómetros de tipo ABBE. Cuando se selecciona el "modo de medición cuando está estable", el J157 espera automáticamente hasta que la muestra se haya calentado o enfriado electrónicamente a una temperatura predefinida antes de iniciar una medición.
Sistema electrónico doble de control de temperatura
A diferencia de otros refractómetros de temperatura controlada, el J157 PLUS tiene control electrónico de la temperatura tanto de arriba como de abajo de la muestra.
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.
Presionador de muestras opcional
El refractómetro digital J157 PLUS está disponible con un prensador de muestras de temperatura controlada opcional que toca la muestra. En comparación con la tapa estándar de temperatura controlada, el prensador opcional reduce el volumen vacío del área de medición, reduciendo así en gran medida la evaporación y ayudando al mismo tiempo a distribuir uniformemente muchos tipos de materiales, incluidos los semisólidos y las pastas, sobre el prisma de medición. Esta característica ofrece un rendimiento de medición mejorado en muchas muestras.
More about Rudolph Refractometer Sample Cover Options
Digital Refractometer Auto Measure Option
La Opción de Medición Automática de Rudolph permite que el cierre y la apertura del prensador inicien y terminen una medición. El operador sólo cierra la tapa para comenzar a medir y levanta la tapa para detener la medición. El cierre y la elevación de la tapa funcionan como el inicio y el fin del proceso de medición sin necesidad de tocar el botón de medición.
Easy to Clean Digital Refractometer Sample Well
No importa lo grande que sea el refractómetro, sólo se obtendrán resultados precisos si el prisma está limpio. Todos los refractómetros Rudolph Serie J ofrecen un prisma plano y fácil de limpiar que hace que el proceso de limpieza entre las mediciones sea sencillo, incluso con muestras pegajosas.
Escalas definidas por el usuario
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.
Configurable por el usuario
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.
Prisma de Zafiro de Alta Durabilidad
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.
Simple pero flexible
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.
