  • The food industry requires stringent guidelines to insure that the product going out the door is safe and fresh, and remains that way until it reaches the consumers plate. Quality control is crucial during every step of the manufacturing process, as well as during cold storage and transport. We manufacture thermocouples and RTD's custom fabricated to your exact specifications with many options including sanitary tri-clover fittings, transmitters, explosion proof heads, and more. We can also assist with designing and building system to accomplish your food manufacturing goals. We carry pH buffers and other liquid solutions as well as meters, electrodes, and other laboratory equipment to assist with accurate quality assurance. We also offer a variety of options for monitoring and recording temperature, pressure, level, flow, relative humidity, and pH. These instruments include paper chart recorders, paperless recorders and data loggers, and in-transit data loggers for when the product is shipped to its destination. We also handle heaters for different food applications such as heating product and sealing bags or containers with form fill and seal machines and other packaging equipment. We cross over thermocouples, RTD's and catridge heaters for many of the packaging machines being used for manufacturing plants. Our exact match sensors, controls, and heaters can provide a great cost savings alternative than going back to the OEM of the machine.

    Food Industry
  • The Dairy industry requires careful monitoring and documentation of temperature and other parameters such as level, flow and pressure. The USDA requires dairy producers to show proof that their product was produced and maintained according to strict guidelines. Then the product must be stored and transported while maintaining temperatures in accordance with USDA regulations. W. H. Cooke & Co. manufactures temperature sensors for the dairy industry including RTD's with sanitary fittings for CIP (Clean in Place) systems and other applications. We can add transmitters in the heads and custom fabricate to you specifications.
