Type K Thermocouple Probes are the most common general-purpose thermocouple type. Several models are immersible and feature a standard yellow Type K wire and a two-blade male connector for use with many digital thermometers, in general or specialized applications.

MAA-286 Type K Thermocouple Probe is immersible and has a temperature range of -58–572°F (-50–300°C) with an accuracy of ±0.75%. Thermocouple has a handle length of 4.5in (114mm) with probe dimensions of 4x0.08in (102x2mm), LxDia. and a 40in (1,016mm) long cord.

MAA-287 Type K Thermocouple Probe is immersible and has a temperature range of -58–752°F (-50–400°C) with an accuracy of ±0.75%. Thermocouple has a handle length of 5.2in (133mm) with probe dimensions of 6x0.12in (152x3mm), LxDia., and a 40in (1,016mm) long cord.

MAA-288 Type K Thermocouple High-Temperature Probe is immersible and has a temperature range of -58–1652°F (-50–900°C) with an accuracy of ±1.5°C at -40–375°C and ±0.4% at 376–1,050°C. Thermocouple has a handle length of 4in (101.6mm) with probe dimensions of 3.25in (82.6mm), LxDia., and a 46in (1,168.4mm) long cord.

MAA-290 Type K Thermocouple Probe is immersible and has a temperature range of -58–752°F (-50–400°C) with an accuracy of ±0.4%. Thermocouple has a handle length of 4.5in (114mm) with probe dimensions of 4x0.11in (101.6x3mm), LxDia. and a 53in (1,346.2mm) long cord.

MAA-291 Type K Thermocouple Wire Probe has a temperature range of -58–572°F (-50–300°C) with a soldered wire tip and a 47in (1,193.8mm) long immersible wire.

MAA-295 Type K T-Handle Thermocouple Probe has a temperature range of -250–1652°F (-150–900°C), a 10in (254mm) probe length, and a T-handle grip.

MAA-296 Type K Flow-Through Thermocouple Probe has a temperature range of -250–450°F (-150–232°C), probe length of 3.375in (85.7mm), and is designed to measure the temperature of clean fluids in-line at flow rates up to 50 liters per minute.

MAA-297 Heavy-Duty Type K Penetration Thermocouple Probe has a temperature range of -328–1652°F (-200–900°C) and a 6in (152.4mm) probe length for Soft and Semi-Soft Materials.

MAA-298 Type K All Stainless-Steel Thermocouple Probe has a temperature range of -250–1200°F (-150–650°C), an 8in (203.2mm) probe length, and is suitable for use in high-temperature environments.

MAA-299 High-Temperature Type K Ceramic Insulated Probe has a temperature range of -250–2000°F (-150–1093°C) and a cable length of 60in (1,524mm). The probe is ceramic fiber-insulated for use at high temperatures.

MAA-300 High-Temperature Type K Fiberglass Insulated Probe has a temperature range of -250–1300°F (-150–704°C) and a cable length of 120in (3,048mm). The probe is fiberglass-insulated for use at high temperatures.

HMA-320 Type K Thermocouple Wire Probe has a temperature range of -328–400°F (-200–205°C) with a fast-response wire tip and a 36in (914mm) long wire.

Product Q&A

Q: Will this work with fan-forced heaters?

I'm very satisfied with this product. It was exactly what I wanted in my travel trailer, for a lot more accurate heating. Now I can pinpoint it to exactly the temperature I want, instead of guessing, sliding the conventional thermostat back and forth. Will for sure save on propane too! Nice back light when adjusting the temperature, making it easy to see even at night.
