Ohaus RC31P3  Ranger 3000 Count - 3kg x 0.1g Legal for Trade Counting Scale

Ohaus RC31P3 Ranger 3000 Count is a high-precision dedicated counting scale paired with advanced software for counting and packaging parts. Easy to use in multi-step counting operations with three backlit LCD displays and SmarText™ navigation for simple operation. Integrated handles and battery operation provide true portability.

Features a low Average Piece Weight (APW) alert and automatic APW recalculation, Ohaus RC31P3 offers 1:1,500,000 internal counting resolution to handle counting even the smallest parts precisely. Rapid one-second response time provides fast and accurate results. 30 item library data storage function can store 12-digit part numbers, average piece weights, checkcounting or checkweighing parameters, tare weights, and accumulated weights or counts with quick and simple retrieval of frequently used data.

Standard RS232 with optional Ethernet, second RS232, or USB that offers connection to multiple peripherals. Can support two-scale counting through the optional 2nd Platform to support weighing jobs that require a higher capacity platform or additional platform space. NTEP and Measurement Canada Approved.

Application Modes:
 Weighing—Determine the weight of items in one or more weighing units -- lb, oz, lb:oz, kg or g.
 Advanced Parts Counting — Count parts fast for packaging and inventory control uses on the line or in the warehouse, with added software for APW low alert and automatic recalculation of APW during sampling.
 Check Counting/Weighing — Use the bright red/yellow/green LEDs to easily fill containers and packages by weight or by a specified number of parts.
 Accumulation — Keep a running total of all items, by weight, parts count or percent of reference. Great for tracking total throughput during each shift.
