TL0700, K-Type Sensor Probe for K-Type Thermocouple Thermometer/Meter in Temperature Range from to to 700 °C/ 1292°F

I routinely have to put several thermocouples in a very small space which doesn't allow for a lot of tape/etc. for adhering the thermocouple. These TL0260 thermocouples are super tiny, and extremely flexible, which makes them very easy to work with. I have purchased them several times, and have only ever received one that had a problem. The seller (Perfect Prime) responded very quickly to an email, and were extremely helpful and quick with getting the problem resolved. If you need type-K thermocouples that are small and flexible, buy these, and from this seller, you should have no issues.

Works great. The fine wire is nice because it doesn't apply as much force to the object you attach it to. Good quality as well.

I bought one for a high temp (300+C) distillation, got a little browned but still works like a dream. I bought another after I couldn't find my first one and decided to buy a third in case I lost the second one. Great easy to use product, super highly recommended if the specs fit your needs.

Needed a lil calibratuon on my meter, but then workes great to check/calibrate commercial oven thermostats

Overview: Misleading product specifications. Perfect Prime CHANGED the product description here on Amazon and their website immediately after I contacted them! Read below.This is a review of the TL0700 K-type probe *(-30°C to 700°C)*(product specification at the time of purchase)I have been on the hunt for a metal armored probe of decent quality that I could use for checking both small coolers, as well as cooking equipment like convection ovens, for many years.I was super excited to find this probe. A bit costly at $16, but that's fine if the product is quality and lasts longer than simple fiberglass insulated probes.So I buy one. Was satisfied with the quality and feel when it arrived. I take it to work and try it out on a cooler. Keep in mind I have been doing this line of work for a while, so I have a decent feel for temperature by hand.My meter shows the probe is reading a bit high compared to what I know the temp should feel like. Unplugged the Perfect Prime probe and plugged in my ragged old probe I've been using until now. Yep, temp is defintely lower.To further test I decided to grab a glass of ice water and check the probes accuracy. As you can see in the photo, the reading is off by quite a bit. That's well outside of the stated spec of this particular probe.Now for context, what took so long to find a suitable probe was the limitation of most of the probes in this class (with this temperature range) typically are rated to a minimum of 32°F (0°C). Sometimes I need to check temps as low as 0°F.When I found this probe that offered a range of 1292°F to - 22°F, I was excited. Turns out that might have been a lie...I contacted Perfect Prime directly via email after finding the large discrepancy when testing my probe in ice water. I pointed out that most of the other similar range probes in this class only specified down to 32°F (0°C). I asked them if the probe model I purchased was supposed to be accurate at that lower range (despite what the specs claim), or it if was a mislabled product.To my surprise they said yeah it's mislabled and then told me to buy a different probe that did not meet my criteria. They also asked me to check if the probe was a K-type. I provided the exact model probe (TL0700) when I emailed them. Why are you asking me to verify the type of probe??They didn't offer to replace it, refund, or return. Only a link to buy a different product.The part that really annoyed me is that they changed the product description on both the Amazon page and their website to show that the probe had a lower limit of 32°F (0°C) like all the other similar probes of this range.(this was done on the day I contacted them)Here is the problem with that.Check the "Date First Available" field on the Amazon description.This product has been in production and sold on Amazon since 2016!Are you telling me in nearly 8 years time you were not aware of a major discrepancy on the specification of your own product?Sorry I don't buy it.Further, look at my photos. Both the probe and the packaging are clearly labeled with this "erroreous" information.You can't tell me this has gone unnoticed for 8 years.So I emailed them back with a response to their inquiry about checking if the probe was K-type.I also sent them the 2 photos I am posting here, and asked for clarification if the product packaging and probe label were indeed incorrect.That email was sent on October 8th. I have yet to receive a reply to this day.I ended up keeping the probe instead of returning it. Trying to not put too many returns on my Amazon account.I still use it occassionally for measuring cooking equipmemt in the 300-500°F range. Accuracy is ok I guess.I clearly understand this is a $16 product. But try to understand my frustration with spending quite a bit of time finding this particular probe that finally met the criteria I have for my work.I was so happy to have found this, only to experience this disrespectful disregard of customer concern.This is not a hobby tool. How are we to trust the accuracy of this brand when they themselves don't know the specification of their own product?If you have put any trust in this brand for important measurements or work, you may consider reevaluating.Or at the least, find a way to verify the accuracy of your equipment.

Withstood multiple heating cycles at 500° C with no problems.

easy to use

Works good . I used it for tracking my pond temperature.
