Unmatched Capabilities in a Fully Portable Refractometer
Rudolph brings decades of leadership with High Accuracy, Bench top Refractometers to Portable Refractometer Instrumentation
With the experience and innovation gained from over 2 decades of leadership in Refractometer design and manufacturing, Rudolph introduces the new benchmark for Handheld Refractometers. The J27 Refractometer is entirely untethered yet refuses to accept the compromises in performance and accuracy of typical Handheld instruments. Now measure everything anywhere still with laboratory level accuracy
Temperature Controlled Measurements at 20 and 25°C
The weakness of most portable Refractometers is they do not control temperature. Refractometer measurements are often highly sensitive to drifting results because mathematically correcting for temperature alone does not work well when the ambient temperature is changing. Only precise temperature control will result in the measurement accuracy many users require.
The Rudolph J27 Peltier Temperature Control at the prism surface allows for improved accuracy and greater stability. Precise heating and cooling ensures stable and accurate measurements at either 20 or 25°C. Select the J27 series with temperature control for precise measurements when working with samples that are very hot, very cold or are not Sucrose, Glucose or sugar based.
For example, a glycol sample must be measured with precise temperature control for an accurate measurement – temperature correction for sugar cannot be applied to non-sucrose based samples. A sample coming from a hot kettle on a production line must also be temperature controlled as temperature correction will not be accurate for a sample far from room temperature.
High Durability Industrial Sapphire Prism
Synthetic sapphire prisms have similar hardness to diamond and can be cleaned with a paper towel. This makes sample cleaning fast and easy.
Regardless of an portable refractometer’s specified accuracy, a refractometer’s real-world performance depends on how well the instrument is cleaned between samples.
User friendly GUI and Bright LED, Touch Screen Display
Extremely easy to use Graphic User Interface (GUI) and the availability of 10 different Languages on a brightly lit 7 inch (178mm) touch screen makes this the most user friendly Refractometer on the market today.
The interface is a bright, LED touchscreen, with an easy to navigate GUI. No more difficulties reading measurements in very bright or dark environments in the warehouse or field.
Portable Refractometer with Handheld Flexibility
The J27 is powered by a Lithium-Ion battery that is easily recharged, your J27 is ready to go everywhere you need to make measurements. This might be at the loading dock when receiving incoming raw goods or out on a distillery floor. The Lithium Ion battery can be charged in
approximately 2 hours providing up to 4 hours of
constant measurements under heavy usage or 8 hours of normal usage. Included is a Charging Station for convenient stationary charging.
Portable Refractometer Laboratory Accuracy – Everywhere You Need to Measure
Most portable Refractometers only provide for 2 or 3 decimal place accuracy and results are prone to drift. By combining laboratory level measurement module design, and true Peltier Temperature Control, Rudolph provides accuracy to the 4th decimal place. Laboratory accuracy in the field eliminates rechecking of materials in the Lab allowing users to test right in the field, on the receiving dock, or in a formulations area. Materials are measured for a reason, so why settle for just 2 or 3 decimal place accuracy when you can have steady and reliable 4 decimal place accuracy?
