DESCRIPTION
Simplify your cooking and repair tasks with the TempPro TempScan PLUS TP420 2-in-1 Instant-Read Thermometer for Cooking. Its infrared sensor quickly reads surface temperatures, while the built-in probe delivers precise internal measurements for meats and more. The 180° rotating probe offers maximum flexibility, whether you're checking a roasted chicken or grilled steak. From kitchen use to HVAC and automotive diagnostics, this versatile tool saves time and improves accuracy.
WHO IT'S BEST FOR
Best For:
For the cook who wants surface and internal temps in one tool: Point at the griddle to check surface heat, then use the probe for internal doneness. Two measurements, one device, no switching tools mid-cook.
For the home DIYer who also cooks: Check the grill temp, inspect the AC vent, test the engine. Infrared covers -58°F to 1022°F. The probe handles internal food temps. One tool for kitchen and garage.
For the backyard griller who checks both the grill and the meat: Infrared tells you if the pizza stone or griddle is hot enough. The rotating probe goes into the chicken or brisket. Pull it when the probe says it's ready.
Not Ideal For:
Those who only need surface temperature checks: If you only scan surfaces and never check internal food temps, the TP450 or TP410 gives you precise infrared readings at a lower price point.
Those who need more precise surface targeting from a distance: The TP420 has a 12:1 ratio. For tighter targeting from further away, the TP450 with 16:1 and dual lasers locks onto surfaces more precisely.

FAQ ABOUT TP420
It works well, easy to use and easy to secure on my fridge with the built in magnetic strip. Will definitely recommend others buy this.
Trying to understand why you keep burning your eggs on the griddle? Don’t know why your pancakes are black charr on the outside and liquid batter on the inside? It’s because you aren’t managing the temperature on your griddle correctly. This little tool will help you do just that. If you wanna sear a steak or get that perfect crisp on your smash burger - you need to know at what temperatures you are operating your griddle. This handheld tool will let you do this without touching the heat. All the user has to do is aim it at the surface and get an instant reading on the screen. This device has a backlit screen, easy to use interface (switches between F and C degrees easily), and has a convenient auto shutoff at 90 seconds. The attached meat probe is yet another added benefit.Overall this device is hefty, and will last if taken care of. The package coming with batteries for immediate operation is a plus. If you need one of these for your griddle times - look no further, this is the one.

Love this for my blackstone griddle.
Best thermometer I've used. The surface temp is very easy to use and has been incrediblyhekoful withtempingmyngriddke and the addition of a probe on the same device is fantastic.
Just stepped up to this. Great for grilling,BBQ, griddle.
Works great.
works great, i use it primarily for HVAC related stuff.
Works great
Easy to use, love the multi purpose design
Works great! Awesome product!
Measures various places on my griddle plus inside meat temp.
Got this off a recommendation of a YouTuber I follow for griddling advice and tips. so far, so good. A kind of small thing that I appreciate so much was including batteries!!! I don’t carry aaa batteries too often so that saved me a trip to the store!
Great product
I like having the combination of proble and infrared.
Very happy with this product so far. Great tool to use with my smoker.
Perfect combination of an IR sensor and a temperature probe which is especially great if you have a griddle.
I like it has a probe and infrared to read temps. I can measure the temp of the griddle and then the temp of the meat on it. A must have for cooking.
This one does a good job at both and comes in handy when using a Blackstone and it's pretty quick reading
Works great!
Great thermometer! Super easy to use.
The TempPro works great, just as advertised
Works as described.
I love this tool. Didn't realize it when I bought it, but it has both non skid pads and magnets on the bottom so it stays put on the counter or side table of the grill. Bought one in my summer house and bought another one the day I got to my winter house. Use both the infra red setting frying pan temp (omelets turn out much better if you fry at exactly 275 degrees) and probe for internal temp of meat.
I previously had a Thermapen IR by ThermoWorks (gonna call it "TIR" going forward) but I accidentally dropped it in a sink full of water which fried it immediately. I tried contacting support and they had me send it in, but ultimately they basically told me to pound sand and get a new one. I didn't want to drop another ~$175 so I figured I'd give the TP420 a try as there are very few options that have both a probe and IR (both of which I use constantly!)In many ways I like the TP420 better. It has a backlight (TIR doesn't), it can take a running average temperature (TIR can't), and the probe/infrared act totally independently. With the TIR it's one or the other, and it was often finicky because it wouldn't register the probe being closed so I'd have to squeeze it tightly to use the IR function. Also, the TIR costs ~$175 while the TP420 costs less than 1/4 that (as I type this). The built-in magnet on the TP420 is also a nice touch.Really, the only few things I like better about the TIR is that it looks sleeker and it turns on when you deploy the probe, with the TP420 you have to press an "on" button, which is nit-picky, but I do like the immediacy of the TIR. The TIR's probe is a bit faster, however, ThermoWorks prides themselves on how fast their thermometers are and the TP420 is no slouch. The TIR realistically takes 2-3 seconds and the TP420 is more like 4-5. It's just enough to be noticeable, but not enough to make much difference unless you regularly have to do many temp checks in quick succession.Accuracy is quite good! I have a latest-gen Thermapen One (non-IR version) which comes with a calibration certificate, and it along with my Anova Pro sous vide circulator agree with each other right down to the decimal, so I'm fairly confident they are quite accurate. My TP420 tends to read about 0.7 to1.2 degrees (F) warmer, which isn't enough to worry about for most applications.I definitely recommend this over the Thermapen IR I had before. Little accidents are very common in the kitchen and I'd much rather be out ~$40 than $175!
Works Great. Reordered one for our son.
This is a must have if you do any grilling or griddling.
Works great. Functional and well made.
This is the PERFECT thermometer for my blackstone!! Works like a Champ!!
Excellent thermometer. Works great with the griddle top
