J57AB/J157AB Refractometers for measurement of urea concentration in diesel engine additives

Product catalog summary

Introduction
The document provides technical details about the J57AB and J157AB refractometers, which are used for measuring urea concentration in diesel engine additives. These instruments are designed in accordance with DIN 70071 and ISO 22241-2 standards.

Standards
The refractometers comply with DIN 70071 and ISO 22241-2, ensuring they meet industry standards for accuracy and reliability.

Basic Operation
The J57AB is a variant of the J57HA model, while the J157AB is a variant of the J157 model. Both models have enhanced temperature performance, maintaining accuracy better than 0.02°C, which aligns with the specified standards. The J57AB displays results in refractive index, requiring manual calculation of the wu number, whereas the J157AB has built-in calculations to display and print the wu number directly.

Optional Accessories
The J57AB can be equipped with various accessories similar to the standard J57 model, including printers, computer software, barcode readers, automatic sipping systems, and autosamplers.

J57AB /J157AB Refractometers for measurement of urea concentration for diesel engine additives Standards Designed in accordance with DIN 70071 / ISO 22241-2 Basic operation The J57AB is a sub model of the J57HA and most details on the Technical Bulletin 925 apply, the J157AB is a sub model of the J157 and most details on Technical Bulletin 911 apply. The differences between the AB and the standard models are; Temperature Both instruments have improved temperature performance to better than 0.02oC meeting the requirements of DIN 70071 / ISO 22241-2 Scale The J57AB displays results in refractive index and the operator then uses that result to calculate the wu number. The J157 has the calculations built in to display and print the wu number. Optional accessories The J57AB refractometer can be supplied with the same range of accessories as the standard J57 including; - Printers - Computer software - Barcode reader - Automatic sipping system - Autosampler J157AB J57AB Rudolph Research Analytical 55 Newburgh Road, Hackettstown, NJ 07840 • 973-584-1558 Fax: 973-584-5440 • Email: [email protected] • Internet: www.rudolphresearch.com J57/J157AB Refractometer Technical Bulletin
