Product Overview
Long Insertion Temperature Probe with Lead Wire and Case - Wahl TC811 Type K
Product Condition
Used. Basic testing performed. Temperature readings appear reasonable during simple checks, but calibration has not been verified due to lack of calibration equipment. Probe measures approximately 24 inches in length and about 30 inches overall to the end of the handle with a lead wire approximately 4 feet long. A storage box is included but is not the original box. Full manufacturer performance specifications are not available.
Carefully packed and shipped same business day from our Idaho warehouse. Online since 1999. Honest equipment and straightforward service.
Product Overview
Wahl TC811 Type K thermocouple probe designed for insertion temperature measurements in industrial, laboratory, and maintenance environments. The probe features a 24 inch sensing stem that allows measurement deep inside ovens, ducts, tanks, or other process equipment. A handle and attached lead wire connect the thermocouple junction to compatible thermometers, controllers, or data acquisition instruments. Type K thermocouples are widely used due to their durability and compatibility with many temperature measurement systems. Long insertion probes like the TC811 allow technicians to measure internal process temperatures while keeping hands and instruments farther from heat sources.

Frequently Asked Questions
What thermocouple type does this probe use?
The probe uses a Type K thermocouple, one of the most widely supported thermocouple standards for industrial temperature measurement.
How long is the probe?
The sensing probe is approximately 24 inches long, with an overall length of about 30 inches including the handle.
How long is the cord?
The attached lead wire measures approximately 4 feet.
Has the probe been calibrated?
Calibration has not been verified. Basic testing showed readings that appear reasonable, but no calibration equipment was available to confirm accuracy.
Is the storage case original?
A storage box is included with the probe, but it is not the original manufacturer box.
Long thermocouple probes exist to reach the temperature that shorter sensors cannot. Insert, measure, read the instrument—the next data point waits inside the process.
