Review: Monitoring - Nice thermometer with a scale and digital read out for monitoring temperature. Bright display, easy to see read-out, good value for the money.
Review: Pleasant, sharp display. - 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 .

### ⭐⭐⭐⭐ Trolling motor pwm controller
*by A***Y on January 16, 2026*

I put this on my pwm controller for my trolling motor to monitor the temperature of the board. I checked it with other temp probes and it's very accurate. Very nice and crisp display. I have two issues with it, that are small. Not water resistant and the screen is small and I struggle to see the numbers from 4 feet away. Other than that, useful and accurate
