Review: It just works. - I'm using it over the air intake of my main PC, to monitor room temperature. It's a nice little add-on so that I know that I'm not really freezing in the winter, it just feels that way. Getting the clip off so as to read in degF was a pain, though. Not much room to reach in, and that little sucker was in there TIGHT! Edit: Bought two more, so I will have one for intake air temperature, one for room temperature, and one for outside air. In the photo, all three probes are taped together. I haven't compared them to a calibrated thermometer, but they all read very close to each other, so it's good so far.
Review: Hot or Cold, Always in the Know - 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.desertcart.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.

### ⭐⭐⭐⭐⭐ Pleasant, sharp display.
*by G***E on July 24, 2024*

This KEOTEK Digital thermometer was soft and on the eyes to look at day and night.. An excellent item for use on a car dashboard to monitor engine temperature. If the sensor lead is too short, ordinary speaker wire can be used to lengthen it. The sensor lead is just regular, very thin, about 22 gauge wire. I would suggest cutting the sensor lead a few inches outside of the sensor housing to lengthen the lead. The sensor is soldered on two tiny tabs on the PC board and the new lead can be soldered ther in place of the original. I did that but If a person is not skilled enough to do that then just add on to the existing wire externally. Saves time prying open the device housing and tearing two small wires from the backlite main LED. Accuracy is excellent. If a person needs beater accuracy then he'll have to pay more for a lab grade temp measuring devices. All in all the KEOTEK A great little device and sold and a lot of value for an excellent temp gauge sold at low price .
