A probe for a thermometer can come in different forms.  It could be a probe that is attached right to the thermometer that is known as a pocket thermometer.  This type of temperature reading device usually comes with a stainless steel probe that measures in different lengths.  The most common type of pocket thermometers are used by cooks and household chefs alike, but this type of probe thermometer where the probe is connected directly to the reading display in one piece is used for other things beside cooking.  Some uses for this type of probe might be for compost testing where the probe could be 3 ft.in length.  Some of these thermometers are used in laboratory settings.  This type can be known as a straight stick probe thermometer.

Let’s talk about another style of probe that connects to the main unit by a plug-in design where the probe has a certain style connection.  Some of the styles are K, T or J type connections.  These connections can be wires or hard stainless steel probes.  They connect to a device called a thermocouple which is a thermometer that measures temperature with 2 wires made of different metals that are joined together.  The potential difference between the wires is the measure of the temperature of the object they are touching.

When a hard stainless steel probe is connected to a thermocouple, it is considered a thermocouple probe.  This probe can be curved for hard to reach places.  Some wire probes and hard probes have the capability of reading very high temperatures in the thousands of degrees.

In this style where a thermocouple is used, there are several benefits to choose from such as using multiple probes or wires to enable you to take several temperature readings at the same time.  You may also be able to interchange the different style probes on the thermocouple.

This style probe that connects to a thermocouple is found to be very beneficial for individuals who need to take more than a straight stick-style probe temperature.
