Central States Enterprises has been using the Porta-Probe from day 1 of the company’s history. It was discovered, early on, that this equipment suited our purpose in providing our customers with a tool that could adequately sample virtually every stored commodity. The equipment could be tailored to probe both shallow depths as well as deep sampling. We are able to quickly identify grade issues for our clients so they can make sound decisions based on different grade variables needed for marketing, maintaining quality, and when best to time there fumigations or insect control measures. We routinely put hundreds of hours on our probes (Central States Enterprises owns 4 units) annually. Mechanically speaking we have not had any issues with any our probes. Central States Enterprises is committed towards helping our customers maintain grain quality and marketability. The porta-probe is the right tool to assist us in this endeavor.
