When it comes to seed capsules, two factors stand out: The individual capsules must not be too large and must be cleanly singled. Exactly one capsule per planting point must always be used and no capsule must hinder the mechanical distribution because it is too big. To achieve a very high efficiency, the tablet quality must be monitored continuously. Here not only size with regards to the maximum diameter is of interest, but also the shape plays a decisive role in the singling. Measurements show that not only the length/width ratio definition is a factor. Depending on the product at hand, other more modern definitions are available.

A very rapid and efficient way of checking seed capsules is offered by the HAVER CPA 2-1. Due to the large channel width and the high resolution over the entire width, high quality measurement can be carried out in the shortest time. Also an online or even an inline solution is available with various interface standards.
