3 Pcs K Type Temperature Sensor Thermocouple Probe Copper Wire 5 Meter 16.4Ft

Used it to measure the temperature of a wood fired Pizza oven that the students at Immaculata University built. The probes worked well and the students learned a lot about thermal conductivity of bricks.

The sensors work perfectly i only have one complaint, the insulation material on the cables is very fragile and After little use it gets flaky and itches a lot if you get in on your skin.

These will fit my needs for smoking meat. Longevity has yet to be determined.

All the information on the living stated up to 500c temperature rating. When the package arrived the description on the package stated that the max temp was 204c. One of the individual probe packages was split open and the probe tip had extra uninsulated wire twisted together.

Worked perfectly

It is nice to get some sensors that are accurate! I wanted more than one so I could test them against each other. They were all within the listed tolerances. They also tested very well alongside another very accurate sensor that I have.

I have a dedicated Omega handheld digital thermometer as well as a Fluke 110 meter with add-on thermocouple attachment, and both of them needed new temperature sensors since the wire insulation on the originals was getting badly frayed.I decided to try these out since I am just a DIYer and hobbyist, not somebody who relies on precisely calibrated temperature data on a daily basis. For what I do, they are a great value. They are longer than the original sensor wires and work as well as the originals on both instruments, fitting securely into the jacks and operating without any surprises. Since I got three, I even have a spare!If you are like me and just want to see how well your HVAC or car air conditioner is working or take other non-critical temperature measurements, these are definitely worth a try. I'm not sure how long the fiberglass insulation on the wires is going to last, but I don't anticipate any problems since both of my meters are stored in cases and not abused.I'm not set up to evaluate how precisely accurate these are. If that is a concern to you, you probably want to stick with replacements from Fluke or another big name (that will cost a lot more). For my needs, they are an excellent value.

These are inexpensive K type thermocouples with a long cord and are a good value. However, they don’t live up to the product description. By that I mean, they cannot be used for measuring temperatures as high as indicated in the product description which states: “Temperature measurement range is from -20 celsius to 500 celsius degree.” Thus, this mediocre performance only rates three stars. I’m sure the thermocouple itself is capable of measuring temperatures in the full stated range. The insulation is the problem.Close examination of the cryptic plastic baggie (the only ‘documentation’ provided) reveals that these thermocouples are TP-01 of a series of thermocouples that the company sells. You can only tell the model by comparing the tiny drawing to the actual thermocouple that you receive. Nowhere is the model of the thermocouple indicated in the product description page or the product itself.And, indicated on the baggie is a chart, and this lists the TP-01 as “Suitable for measuring the air temperature: -50 – 204°C or up to 399°F. So, what happens if you exceed this range? The insulation becomes singed as shown in the attached picture.I checked the probe at two temperatures: in an ice bath, and then in boiling water. The temperature accuracy was good – within 1 degree C at these two points. The description does say that this is not for liquid measurements. But that didn’t matter for my brief freezing/boiling water test where it worked fine, much like other thermocouples I’ve tried, and it had a fast response.Then I tried it in my toaster oven to see how accurately the toaster oven would hold at its maximum of 450 °F. The thermocouple worked fine and showed the toaster oven averaged at 475°F, but the insulation quickly became singed. It was then crackly once cooled. That’s when I noticed the temperature limitation printed on the baggie. Also – this fiberglass insulation is prone to shedding. My hand became itchy after use, so I would say to wear gloves when handling. The plastic connector is cheap feeling.Otherwise, it’s a type K thermocouple and seems to work fine. It may be great for an application where it is installed once and then not handled, and where the temperature is below 400 degrees F. I’d look for something better for any more demanding applications.
