An easy-to-operate, no nonsense counting scale that weighs extremely light parts and reduces the time required to count. The PC-905, using vibrating beam technology provides the highest level of counting accuracy, at an affordable price. Manufacturers and suppliers of small components for computers, communications equipment, electronics and other products know the importance of accurate counting and weighing.

Counting parts that are so small and light that they can barely be seen is a daunting and time-consuming process that is prone to error. Now even small-component manufacturers and suppliers have a counting scale alternative that ensures accuracy and reduces time required to count parts. The Avery Weigh-Tronix PC-905 digital counting scales have the ability to weigh parts as light as 0.00001 lbs. in less time with accuracy up to 99%.


Which Parts Counting Scale is Right for Your Company?

Avery Weigh-Tronix, the inventor of the electronic counting scale, continues to lead the market with innovative technology at affordable prices. As you are evaluating scales, ask yourself the following:

1. Is it easy to operate?
A counting scale that is difficult to operate or requires multiple keys strokes leads to confusion and inaccuracy. The reason you purchase a counting scale in the first place. Avery Weigh-Tronix counting scales are simple, flexible and easily operated with one keystroke.

2. What is the risk of operator error?
Increasing the number of parts hand-counted during the sampling process increases the risk of human error. The PC-902 will not allow counting to continue until there is an adequate sample size (0.02% of scale capacity) to get to the accuracy rate you select.

3. How accurate is the scale?
Counting scales with different internal resolutions have different levels of accuracy. Its like measuring the diameter of a steel bar in 1/4 inch increments, 1/8 inch increments or a micrometer. Avery Weigh-Tronix counting scales use T750 Vibrating Beam Load Cell technology to achieve superior count performance and unequaled internal resolution and accuracy.

Accurate in the toughest environments
These counting scales are very rugged and able to stand up to tough industrial environments. The scale’s design protects them against overloading and shock loading, creating hard wearing yet extremely accurate instruments.

Easy to use interface
Feature an easy to read backlit LCD display, for use in low light conditions. The PC905 has a full numeric keypad for more sophisticated data entry, while also being easy to use. The PC-905 can also link to a remote base, allowing the scale to be used to weigh both small and large items.

Legal for trade
The scales are also legal for trade, making them appropriate for commercial applications where product is sold by weight. Available in a range of capacities, from 10 lb to 100 lb (5kg to 50kg).

The PC-905 includes a bi-directional RS232 I/O port compatible with a PC or various text printers. Bar code labels containing piece weight, tare weight, and count can be printed on thermal label printers. Bar code scanner provides input of piece weight. The weight platter size on the 25, 50 and 100 lb models is 12.6" x 14.08" (31.5 cm x 35.75 cm). The 10 lb model the weighing surface is an 8" (20.3 cm) diameter platter

Companies need counting scales for inventory and quality control. Achieving inventory control requires a delicate balance. Too much inventory is money sitting on the shelf that could be put in the bank. Too little inventory means manufacturing down time and missed shipments. An accurate parts inventory leads to greater efficiency at a lower cost — essential for every industry. Maintaining quality control is also critical. Companies want to give their customers exactly what they paid for. Time and again, shipping less than ordered leads to dissatisfaction and lost customers. Accuracy translates to freeing up of capital and satisfied customers.

An easy-to-operate, no nonsense counting scale that weighs extremely light parts and reduces the time required to count. The PC-905 available from Central Carolina Scale using vibrating beam technology provides the highest level of counting accuracy, at an affordable price. The PC-905 is supplied with a full numeric keypad and optional connection to a remote base or floor scale.
