A&D Weighing HD-30KB HD Series Counting Scale, 60 lb x 0.01 lb

The A&D HD-30KB has a maximum capacity of 60 lb (30 kg) with 0.01 lb (0.005 kg) readability. It features a large 300 × 380 mm (11.8 × 15 in) weighing platform, making it suitable for parts counting, inventory control, packaging, manufacturing, and warehouse applications.

The HD-30KB has a minimum sample unit weight of approximately 0.25 g and an internal resolution of up to 1/120,000. These specifications allow the scale to count components that weigh considerably less than its normal displayed weighing increment when appropriate sampling procedures and stable operating conditions are used.

The HD-30KB features A&D's Automatic Counting Accuracy Improvement (ACAI) technology. ACAI automatically refines the calculated average piece weight as additional parts are placed on the scale. This helps compensate for small weight differences between individual pieces and improves counting accuracy when processing larger quantities.

Yes. In addition to standard weighing and parts counting, the HD-30KB includes a comparator function for determining whether results are below, within, or above established limits. It also provides an M+ accumulation function for adding multiple weighing or counting results, which is useful for packaging, filling, inventory, and batch-counting operations.

Yes. The HD-30KB can operate using the supplied AC adapter or six C-cell batteries, and it also supports the optional AD-1681 rechargeable NiCd battery pack. A&D lists approximately 200 hours of operation with alkaline batteries under specified conditions, making the scale practical for mobile inventory work or locations without convenient access to AC power.
