Thermometer with Probe

I bought these to monitor my central heating system, specifically flow and return from my combi boiler and also to aid with balancing radiators.I was a little doubtful about accuracy/consistency, given the price, but with Amazon to stand behind them I though there was no risk if they were a bit pony. As it turns out I think they are really excellent value and plenty accurate enough over the expected temperature range of use. I've compared them at 20C and they are within 0.5C. At 70C the gap is up to 2C, so just +/- 1C. Happy days!Time will tell how long they last, but nothing to complain about right now (day one).Edit : I've been moving these round the house to measure different heating success within each room and now I've installed three (see photo) to monitor my condensing boiler flow and return temperatures. This data can be accessed through fiddly menus, with lots of button presses, but now I can see everything I need at a glance. Readings match the boiler figures within a fraction of a degree and mostly the difference is down to lag. Stellar performance, especially for the price.Maybe when the outdoor temperatures really drop and the system is working hard I will use them to fine tune radiator balance - that was another thought I had in mind when I bought them - although it seems pretty good already. Accuracy is certainly up to the task.

Great pack of thermometers, are a handy size with a decent cable length and perform accurately with each other and against a more expensive digital room thermometer I already have. Have used these at home and also in the caravan both in the living space and to monitor fridge temperature and an very pleased with them so far. Screens are clear and readable from a few meters away. They are small enough to be unobtrusive and handy for discrete placement. Quality seems fine but can't comment on battery life yet. Really pleased with purchase and would recommend. I would note that they arrived with batteries in and already on so I guess mileage of original batteries and overall lifespan may vary I guess.

I’ve been using the Thlevel Digital Thermometer for a couple of weeks now and I’m very impressed. It’s consistently accurate—within ±1 °C of my trusted kitchen thermometer—so I feel confident in the readings whether it’s for cooking, checking my aquarium, or fridge temperature in fact I’ve ordered more as they are so usefulThe lead is particularly impressive—a full 1 metre long—so I can position the display outside of hot areas (like ovens or direct sunlight) while the probe reaches deep inside. That flexibility is a game‑changer for multitasking in the kitchen or monitoring terrarium conditions .A few extra highlights:• Waterproof probe: I appreciate that I can immerse the probe in liquids for drinks, soups, or tanks without worry—just don’t dunk the display unit• Compact and simple: With its small body and clear LCD display, it’s easy to read at a glance and stash anywhere.• Ready to go: Batteries are included, so it arrived fully functional and working out of the box.⸻Bottom LineWhether you’re cooking, caring for pets or plants, or just want accurate fridge-freezer readings, this Thlevel thermometer feels like a premium tool without the premium price. The long, sturdy lead and trustworthy readings earn it high marks all around. Highly recommended.

I’ve been using these for a month. 1 that sits outside the window to know the temperature outside in the morning. These are within 0.5c of the temperature, however when exposed to sunshine the metal clearly heats up like a car.So when it’s about 30c outside it reads over 45 in direct sunlight. Going to have to figure out how to have this outside in the summer with a close to accurate temperature.I have 1 in the bedroom indoors so I know how hot it is inside. Also keep 1 in the office as when people complain it’s cold, I can state the temperature.

Bought these in October 2024 for use in our freezer to monitor temperature not expecting much but hoping for the best. It's now January 2026 and I've just had to replace the batteries. That's over a year in sub zero temperatures and still working as good as new!Tip: if using in a freezer put the end of the probe in a matchbox or similar to avoid direct contact with frozen stuff and place somewhere near the freezer center. I used blu-tac to place the display.Cheap as chips and highly recommended!

I have bought two lots of these thermometers. They are small, easy to read, versatile on account of their remote sensor, and cheap. I have used them to insert the sensors into the foam insulation of the hot water cylinder, to show the water temperature at different levels.Having bought eight of them, I could see how accurate they are. There is often a variation between the thermometer reading the highest and the one reading the lowest. It's not much - perhaps about 1 degree Celsius at most.However, the main problem is that when a new battery is needed, the battery compartment cover is quite flimsy. The small lug holding it tends to break rather easily, either when you are opening the compartment or even spontaneously.As with all things, you get what you pay for!

Small thermometer just right for fridges and freezerWorks well accurate ans easy to readDon’t know how long battery lasts yetHappy with purchase

good

Ik heb ze gebruikt voor onze koelbox, wel experimenteren waar de sensor kwam, ongeveer halverwege de hoogte en diepte van de box

Akvaryum için aldım, acabalarım vardı su geçirir mi, doğru ölçüm yapar mı gibi ama tam bir fiyat performans ürünü çıktı. 4 adedi de tüm testlerimde -+ hata payı olmadan doğru sonuç verdi. Satıcıya teşekkürler.

Llegó en perfecto estado y funciona a la perfección.

parfait et précis
