Probe Type and Temperature Range

This Value Brand Type K temperature probe measures surface and air temperatures from -58 degrees to 932 degrees Fahrenheit. It is suited for technicians who need a direct-contact sensor with a mini plug connection. The ungrounded thermocouple design helps reduce electrical interference in industrial or HVAC environments. Buyers who require a different thermocouple type or a wider temperature span should look elsewhere.

Installation and Common Issues

The probe terminates in a standard mini plug for quick connection to compatible meters or controllers. Its nine-inch probe length and three-foot cable allow access to ductwork or equipment surfaces without strain. The most frequent issue is plugging the mini connector into a mismatched jack, which yields no reading or erratic data. Users who need a larger connector or a wireless transmitter will not be served by this model.

Compatibility Checks Before Ordering

Verify that your measuring instrument accepts a Type K mini plug and covers the -50 to 500 degrees Celsius range. Confirm the probe’s ungrounded construction matches the input requirements of your meter to avoid ground-loop errors. Ensure the nine-inch insertion depth and cable reach suit the intended mounting location. Installations requiring a grounded junction or a different plug format are not compatible.
