Ohaus Counting Scales – Fast, Accurate Parts Counting for Manufacturing & Warehousing
Ohaus counting scales are purpose-built for high-speed, accurate parts counting in manufacturing, warehousing, electronics assembly, and inventory management. By establishing a precise average piece weight (APW) from a known sample, they calculate total quantities instantly — eliminating manual counting errors and significantly reducing time spent on stock checks, kitting, goods-in verification, and production batch management.
Ohaus has over 100 years of weighing instrument expertise, and their counting scale range reflects this in the intelligence of the counting algorithm and the quality of the weighing system at its core. As more reference samples are added to the platform, the scale refines the average piece weight calculation, improving accuracy progressively — a feature particularly valuable when counting small, lightweight components where even minor piece weight variation could affect count accuracy. Accumulation functions allow operators to total counts across multiple batches for large jobs, and checkweighing with over/under/accept indicators supports quality control and pass/fail sorting. RS-232 and USB connectivity enable direct data transfer to inventory management systems, ERP platforms, and label printers for full stock traceability.

Frequently Asked Questions
How do Ohaus counting scales determine piece count?
You place a known quantity of parts (the reference sample) on the platform to establish the average piece weight (APW). The scale divides the total weight by the APW to calculate the count. Ohaus’s counting algorithm refines the APW as more samples are added, improving accuracy progressively. Once the APW is set, add the full batch and the scale displays the total count instantly.
What is the minimum piece weight Ohaus counting scales can handle?
This depends on the model’s resolution. Ohaus counting scales are available with readability as fine as 0.1 g, making them suitable for lightweight components. For very small or light parts, a higher-resolution model is recommended — contact our team for guidance on selecting the right resolution for your specific components.
Can Ohaus counting scales connect to my inventory system?
Yes. Most models feature RS-232 and USB connectivity for direct data transfer to inventory management systems, ERP platforms, and label printers. This reduces manual data entry errors and supports full stock traceability. Contact us for compatibility advice specific to your systems.
Do Ohaus counting scales include checkweighing?
Yes. Most models include a checkweighing function with programmable over/under/accept limits and visual indicators. This allows operators to quickly verify that counted batches fall within specified weight tolerances — useful for quality control and packaging compliance applications.
Are UKAS calibration certificates available?
Yes. UKAS-traceable calibration certificates are available on request for all Ohaus counting scales. Contact our team when ordering to arrange calibration documentation.
