The Extech TM26 is a waterproof temperature indicator with a long stainless steel penetration probe, designed for measuring temperature in liquids, pastes, and semi-solid food. The instrument carries NSF certification for food measurement and combines a panel-style indicator housing with a probe on a 5 ft cable, allowing the display to remain visible while the probe is inserted into the medium being measured.
Listed applications for the TM26 include the food industry, agriculture, refrigerators, laboratories, and warehouses. The combination of NSF certification, the long penetration probe, and the IP65 waterproof housing reflects this application set — environments where the indicator may be exposed to wash-down, moisture, or direct contact with food product, and where the temperature being monitored is inside a liquid, paste, or semi-solid medium rather than on a surface.
Extech Instruments is part of the Teledyne FLIR family. FLIR Systems acquired Extech, and Teledyne Technologies subsequently acquired FLIR in 2021. The Extech brand has been maintained for industrial test, environmental measurement, and food-industry instruments.
