PR SERIES
Precision Balances
Economical Balances For Legal-For-Trade Applications
The PR Series is NTEP certified and Measurement Canada approved, making it suitable for direct
sale applications. The PR is equipped with basic weighing, parts counting and percent weighing
applications, and is capable of displaying weight in grams, milligrams, carats, ounces, and more.
The PR can also be connected to point-of-sale systems or printers via its standard RS-232 port,
or via USB or Ethernet through an interface kit. Featuring an easy-to-read, brightly-lit display and
a simple user interface, the PR is well-constructed for long-term use, and delivers competitive
performance at an economical price.
Standard Features:
• Basic Functionality for Routine Weighing Applications
The PR is equipped with three essential weighing modes, RS-232 connectivity for data
transfer and storage, making it ideal for routine weighing applications.
• Designed for Uncomplicated Operation with Easy-to-Use Display and Interface
Equipped with an easy-to-read, bright backlit display and a simple user interface,
the PR is incredibly easy to operate, with almost no training required.
• Smart Design and Durable Construction
The PR’s small footprint saves desktop space while providing a large weighing
surface. The PR is durably constructed, and features a stainless steel pan
to withstand day-to-day use in the workplace.
