Digital Thermometer Temperature Meter Gauge Waterproof Sensor Probe Aquarium Car PC case Incubator Temp Meter 4 Pin Power Supply Celsius/Fahrenheit LCD Display

Very bright and easy to read it has instantaneously reading. One of my best purchases!

Great temp monitor, love it. Installed it in my 2008 Explorer to monitor the A/C temperature.

I bought the KETOTEK Digital Thermometer Temperature Gauge to monitor the inside temperature of a tower gaming computer after I installed aquarium filter material at all the tower vent locations. Filter link: (https://www.amazon.com/dp/B01KYS02EG?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) The filters are to prevent dog hair and dust from building-up on the cooling fan blades and other interior components. After covering all the openings of the tower with the filter material, I wanted to monitor the inside temperature of the computer tower since the computer remains on 95% of the time. The filters work great with little to no dust build-up, and the interior tower temperature remains constant, reading between 63 and 71 degrees. The temperature gauge is plugged into a USB port and runs 24/7. Using a piece of rigid foam, the temperature probe is anchored upright in the middle interior space of the tower. Some temperature gauges go dark after a short period of time and require being touched to illuminate the face to read the gauge. The face of the KETOTEK Digital Thermometer is easy to read and remains illuminated 24/7, even when the computer is turned off. I have the gauge set to read Fahrenheit, but the gauge arrives set to read Celsius. At the back of the gauge, there is a small pin that, once removed with tweezers, switches from reading Celsius to reading Fahrenheit.

This thermometer works well and seems pretty accurate. However, I should have thought twice about the size of the display (which is clearly shown in the photos and the description). I thought it would be big enough but, I find it a little small to read from any further than a couple of feet away. The colorful display is good, I just wish it was a little larger. I bought the USB style and using a typical USB power block is a convenient power method. The probe wire length is adequate but, a little more length would be ideal. Overall, I think this is a good probe-style thermometer for the cost, with a clear and colorful (although small) display. I give it a solid 4.5 stars.

Surprisingly nice little temperature meter. Clear, bright and responsive. I have the usb powered version and the wired version. Both work great. No problem at all removing the jumper to change from Celsius to Fahrenheit. You might need some tweezers.

Very fast and accurate for increasing temperature and monitoring variation. It is much slower in settling back to a lower temperature when ramped up by touch and holding the thermocouple sensor with my fingers. The display is bright and easy to read. I am using it for my aquarium tank to check the water temp to the readout from the heater. Someone else posted that the thermocouple interface was rusting but I put Aqueon silicone sealant to prevent that and I think that should fix that issue. I plan to but more for my other tanks.

I had to troubleshoot a big class A audio amplifier that we suspected was failing due to overheating. I got several of these thermometers and placed them on the heat sinks and other parts of the circuitry so I was able to get real life measurements easily. I don't know if they are "accurate" since I didn't test them against another type, but the ones I got are consistent, meaning they all measure the same temp under identical conditions. And for macro measurements, such as room temp, they measured the same thing as the thermostat in the AC... so for what it's worth. Plus, oh... yeah... they look cool if you like meters, knobs, switches, lights..... ;-)

I longed for being able to glance at my tank and know the temp without clicking a button or squinting my eyes. It seems +/- one degree off but I am not baking a cake here. It's a full time temp display and a great price.

Nice lcd of temp for my pc compture how hot cpu ... thank u

ES BUENPRODUCTO Y SE PUEDE MPOTRAR EN CUALQUIER MUEBLE, LO UNICO ES EL TAMAÑO DE LOS CABLES, DEBERIAN SER UN POCO MAS LARGOS PARA MEJORAR SU INSTALACION, OTRO PUNTO ES LA CALIBRACION, A MI PARECER NO ESTA CALIBRADO CORRECTAMENTE, LO COMPAE CON TEMOMETRO INFRAROJO Y ME DAN CASI 2 GRADOS DE DIFERENCIA, EL IFRAROJO MARCA 28 GRADOS MIENTRAS QUE ESTE DIGITAL ME MMARCA 29.8 GRADOS

perfect

Tiny and cheap material. On top of that, it is very inaccurate.
