18526-58 Type T Flat-Leaf Thermocouople Probe, with Mini-Connector, 4.5" L, 5ft Coil Cord by Digi-Sense

The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Ideal for measuring in hard to reach spaces due to a flexible tip
• Designed for extremely fast response due to the low mass but yet more durable than other miniature diameter probes (.035" thick at tip)
• Response Time: .75 seconds or greater
• Each probe comes with a color coded ANSI coiled cable: type J-black, type K-yellow, type T-blue, and type E-purple.
