J57HA AUTOMATIC REFRACTOMETER

Product catalog summary

Application
The J57HA Series of Automatic Refractometers is designed for high throughput food applications, emphasizing its role as a quality control tool rather than a laboratory instrument. It features a single flat measurement surface, electronic temperature control, and one-button measurement capability, making it ideal for heavy use.

Automatic Measuring System
The J57HA offers a fully automatic measuring system where the operator places the sample on the prism and presses a button to display results on a backlit LCD. This eliminates the need for manual adjustments or operator determination.

Electronic Temperature Control
Temperature changes significantly affect Brix readings. The J57HA addresses this with built-in electronic temperature control, ensuring accuracy and thermal stability across various sample and environmental temperatures.

High Accuracy
Designed for the food industry, the J57HA provides a Brix range of 0-95% and a Refractive Index range of 1.33-1.53 RI, with high accuracy of ±0.03 Brix and ±0.00004 RI.

Easy to Clean Measurement Surface
The instrument features a flat, easy-to-clean measurement surface, reducing the risk of sample contamination and ensuring consistent performance.

High Durability Sapphire Prism
The J57HA uses a sapphire prism, which is more durable than traditional glass prisms, reducing the need for frequent replacements in high throughput applications.

Lower Cost of Use
Compared to traditional Abbe refractometers, the J57HA offers a lower cost of ownership due to its durable sapphire prism and electronic temperature control.

Calibration
The J57HA supports 1 or 2 point user calibration, storing calibration data in compliance with ISO standards. Calibration is password protected to control access.

User Configurable
The instrument's display and keypad are customizable, allowing configuration to specific application needs and simplifying user interaction.

Options and Accessories
Available options include NIST traceable calibration liquids, acid-resistant sample wells, data capture software, and more.

Specifications
Measurement scales include Refractive Index and Brix, with a control temperature of 20°C and 25°C. The instrument supports a wide range of sample temperatures and offers multiple communication interfaces.

APPLICATION The J57HA was designed to meet the unique needs of food quality testing where the refractometer is viewed as a QC tool rather than a laboratory instrument. A single flat measurement surface, electronic temperature control and one button measurement capability make it perfect for heavy use applications. AUTOMATIC MEASURING SYSTEM The Rudolph J57HA features a fully automatic measuring system. The operator simply places the sample on the prism, presses a button and the result is displayed on a 7.5cm x 10cm back lit LCD. There are no shadow lines to match and there is no eyepiece requiring...
