(#PCH-TC) Ecklund Flexible Pouch Thermocouples are specially designed for conducting heat penetration tests of foods in flexible pouches. On one end of the pouch thermocouple is a Female Locking Thermocouple Connector that connects to the Lead Wire; on the other end is a hot junction that senses the temperature. A pouch thermocouple installs into a special Brass Receptacle. Pouch thermocouples are Type-T and are standard in length at 36". Consider using a Pouch Post to position the tip of the thermocouple inside the pouch.
