PEMENOL 12V Red Fahrenheit Digital Temperature Meter -76F~999F LED Display with Industrial Grade 0.5m K-Type Thermocouple Temperature Sensor M6

Absolutely a game changer for monitoring a wood stove flu temperature. I have a big wood stove add-on that blows hot air into my cabin. I have always used a magnetic thermometer, which I now know is a big mistake. This little digital thermocouple is way more accurate, my flu temp was 450° F when the magnetic thermometer was just hitting 300° F. It very accurately shows the flu temperature response to the slightest change in the flu damper and air intake. When the fan blower came on it correctly showed the flue temperature dropping. And best of all I can now monitor the flu temperature from inside my cabin.

This thermometer is a great value. It is easy to read, and is pretty accurate, coming in pretty close to my SHT3X running off my Arduino Nano. There are no instruction that come with it, but it doesn't need any either. It is really simple to operate and the sepc are right there on the side on the unit. Seems pretty tough, the plastic is strong and clips into place firmly. I think it will work perfect for my amp rack.

This temperature meter works exactly like expected - plug it in and it turns on. The display is easy to read, especially in indoor or shaded areas, but may not be bright enough for reading in direct sunlight. The long probe cable allows the meter to be mounted away from the temperature source, which is definitely handy. It does operate over the full voltage range specified, which keeps it flexible for various applications. The one thing I did note was that there seemed to be some amount of self-heating at the upper end of the voltage range that caused an offset of several degrees. Because of that, i would recommend using a voltage in the lower part of the range if possible. Overall, solid device, especially if precision temperature measurements aren't required.

Very good temperature meter and probe. Accurate and stable readings. Great price. Easy to connect and use.

Have an oven that will display the temperature you have set, but won't display the actual temperature it's achieved. Got this unit, paired it with a DC power supply (https://www.amazon.com/ALITOVE-100-240V-Converter-Security-Surveillance/dp/B07VQHYGRD). Used high-temperature tape (https://www.amazon.com/Hxtape-Temperature-Polyimide-Printing-Soldering/dp/B07DBZ1SW6) to attach the probe cable to the side of the oven near the top, with the probe itself in the air a little bit away from the wall. I just plug in the power supply and it works great, is easy to see, and provides the feature that should have been built into the oven in the first place.

Not Accurate at all. Wildly fluctuating temp readings. Initial power up shows temp +/- 3 degrees f... then temp will incrementally climb, then hang at 40+degrees above ambient temp, then drop incrementally. I've tried 3 different K t-couples, and 2 different J t-couples .. and finally twisted pair - 22awg wires tired together -- no change in temp reading, all different lengths, nothing reads accurate. Temp on meter does not match Laser Temp or Fluke Temp Probe. very disappointing, all I needed was to read ambient outside air. **Sigh**

I used this as a cylinder head temp gauge for a two stroke scooter. I had to power it externally with a nine volt, if I used the scooter’s 12V, it’d freak out every time the thermocouple touched the frame ground. Once I isolated the power tho it was fast and accurate, one of the few temp displays that ranges up to 400+ Fahrenheit. Decent quality for the money. Bright!

We use it in our generator room so we know how hot it gets in thier works great
