Ranger Counting Scale - for easy counting, follow the prompts on the LCD screen, users will be guided through the counting process with ease...Train anyone in 60 seconds! The RC3RS can count parts as small as 0.1 grams in weight. Basically a $1 bill weighs approximately 1 gram so if you where to cut the dollar bill in 10 equal pieces the Ranger RC3RS could count it. This counting scale is perfect for weighing electronic through hole components like 1/4 watt resistors, capacitors or diodes. Platform size 9.5" x 8".

Ohaus RC3RS counting scale offers 2 weighing resolutions (6.6 lb x 0.0002 lb / 3000g x 0.1g default resolution) or (6 lb x 0.001 lb / 3000 g X 0.5 g NTEP resolution). The Ohaus Ranger line of compact counting scales has been upgraded and expanded with new software and enhanced microprocessors for even better performance in demanding industrial applications. Every Ranger Count features a large, backlit LCD display with fast display of weighing results within 2 seconds, as well as a RS232 port for quick connectivity to printers and systems. For use in applications requiring additional filtering, the Ranger series now includes dynamic weighing software allowing weigh determination where vibration is an issue. For advanced counting applications, the Ranger Count Plus offers a numeric keypad for manual entry of key data like average piece weight (APW), sample size and part ID, and information stored in 100 memory locations.

Every Ranger is designed with Ohaus' easy-to-use software interface, making operation intuitive with a consistent feel across all four Ranger lines: Ranger, Ranger High Resolution, Ranger Count and Ranger Count Plus. No matter the industrial need, there is a Ranger for that application!

  • Ranger Count scales offer high performance strain gage loadcells supporting resolutions to 1:30,000,

Ohaus Ranger Count can count into an empty container, starting with a sample. For bulk operations, the user can count out of a full container, starting with the removal of a sample. The Ranger Count includes software to ensure optimization of the APW sample (with selectable accuracies of 97.5%, 99% and 99.5%) and can be set to continue to optimize the APW during the counting process. Set sample sizes can be selected or the user can use a variable sample size to start counting, speeding use. The Ranger Count also can be set to clear the APW between containers, ensuring that each container starts with a new APW sample.

For use in a range of industrial applications, the Ranger Count includes software for Filling/Dosing, allowing weighing of fine powders or liquids. For use with moving or unstable items, the Ranger Count can be set to weigh dynamically, providing an average of the item's weight over time. The Ranger Count can display the gross, net and tare weights stored in memory for checking tare weights during use.

Please note the Ranger Counting Scales must be purchased with the $250 optional rechargeable battery if you want to place the counting scale on a cart and not be restricted to plugging the RC3RS into an AC receptacle. For this reason many people select the A&D HC or HD Series counting scales that operates on AC adapter or six (C type) alkaline batteries. Review all the technical specifications & optional accessories for the RC3RS here.
