Automatic seed counting machine GC-30W-200

for field testinglaboratoryresearch

Overview
The HALDRUP GC-30W-200 is a compact seed counting system that combines precise grain counting and integrated weighing in a single device. Integrated scales enable direct determination of the thousand‑grain weight (TGW) and support counting and weight-based applications in seed testing, breeding, field trials and quality control.

Benefits

• Precise seed counting for determination of thousand‑grain weight (TGW)
• Combination of counting and integrated scales in one system
• Automatic TGW calculation from counted grains and sample weight
• Two counting channels with vibratory feed for even grain separation
• Counting speed up to 20 grains/s
• Suitable for all common seed types
• Freely definable grain count for flexible laboratory workflows
• Integrated code scanner (QR, data matrix, barcode) for sample identification
• RS-232 interface for connection to laboratory and documentation systems
• Designed for seed testing, breeding, field trials and quality control

What is the GC-30W-200?
A seed counting device with integrated scales for laboratory and field use. The GC-30W-200 is designed for applications that require accurate, reproducible and continuous recording of both the number and weight of seed samples. Unlike traditional counters, this system integrates weighing directly into the counting process.

Central application — Direct determination of the TGW
The thousand‑grain weight is a standard quality parameter in seed testing and breeding. It relates seed count to sample weight and provides information about grain filling, uniformity and seed quality. The GC-30W-200 determines TGW directly from the counted number of seeds and the measured sample weight. A user‑defined number of seeds is counted and weighed immediately on the integrated scale, and the TGW is calculated automatically. Larger sample sizes can be used to reduce the influence of segregation or size selection and improve result significance.

Functionality — Counting and weighing seeds in an integrated process
Two parallel counting channels with vibratory feed ensure consistent grain separation and stable counts. The counted sample is fed directly to the integrated scale so that counting and weight data are recorded without manual transfer. The close coupling of counting and weighing increases process reliability and improves comparability between samples, crops and measurement series.

More than just TGW
Flexible counting and weight recording for various seed samples. In addition to standard TGW determination, the GC-30W-200 supports precise counting and weighing of user‑defined sample sizes. Typical uses include:

• Laboratory sample preparation
• Comparative studies between varieties or years
• Weight checks of counted samples
• Documentation and research purposes

Counting and weighing data can be used and processed independently.

Documentation and traceability
Unique sample allocation with integrated code scanner. The built‑in scanner (QR, data matrix, barcode) enables unique identification of samples and batches. Counting and weighing data are assigned directly to the sample and output via a serial interface. Standardized data transfer facilitates connection to external laboratory, evaluation or documentation systems and supports traceable archiving of results.

Typical areas of application

• Seed testing and quality control
• Breeding and variety development
• Field trials
• Laboratory‑based seed analysis
• Sample preparation and documentation

FAQ — Selected answers

• Is the GC-30W-200 always used with 1,000 grains? — No. User‑defined quantities can be counted and weighed; the TGW is calculated from the quantity and weight.
• For which crops is the device suitable? — The GC-30W-200 can be used for all common seed types.
• What is the advantage of the integrated scale? — Direct coupling of counting and weighing reduces manual entries, minimizes error sources and ensures reproducible results.
