Thermocouple Probe Guide

Our thermocouple probes are defined by the numeric series.

The 3000 series is for occasional, light duty. They do not have regular handles, only small gripping surfaces we call a "light handle". For many purposes, these economy probes are the best choice if the usage level is light and the budget is tight.

The 4000 series has three unique "no handle" probes. The AQA49122-K is perfect for many applications that require a slender shaft and a narrow insertion. This probe is designed for, and is ideal for, probing hamburger patties. The AQA49140-K is very specialized for readings of cooking oil vats. AQA49138 bare tip probe has fiberglass insulation (safer than Teflon^Ž for accidental exposure to extreme heat) and useful for oven insertion for fixed location monitoring.

The 5000 series is for repeated usage and commercial, heavy duty applications. There are two main handle types, the heavy duty handle and the bayonet handle.

The heavy duty handle is best for durability and applications requiring substantial pressure for penetration. The heavy duty handle is more resistant to stress and bending forces. Heavy duty handles are only found in the 5000 series of probes.

The second handle type is the bayonet handle. This handle is better for "carry around" surveys and portable thermometer applications since it is lighter than the heavy duty handle. Bayonet handles are typically used with "portable applications", meaning that they are used with thermocouple instruments that are carried from location to location for measurement purposes on a daily basis. Bayonet handles are only found in the 5000 series of probes.

The 5000 series also has some specialized probes for griddle temperature measurement, oven temperature measurement, dishwasher temperature monitoring, hard frozen foods and other specialized needs. Most of the 5000 series that have handles also are fitted with coiled, telephone-style cords. These cords are easier to handle, do not tangle, and extend to 48" for "reaching across" to measure.
