TekPro is perhaps best known for the industry leading Samplex range of Bulk Samplers. These Grain Samplers use a unique, patented gravity-fed spear to efficiently and accurately collect more representative samples than other systems can deliver. The Holmen Pellet Durability Testers are manufactured and marketed by TekPro under licence from Borregaard. It is the industry standard Pellet Durability Tester giving a minute by minute update to help production efficiency. Insect detection is also catered for with the Insectomat. The machines in this range are capable of discovering one insect in either 5kg or 10kg of grain.
