DROK Digital DC Voltage 10-170 Degree Fahrenheit Temperature Monitor Car Motorcycle Battery Voltmeter Thermometer 12V 24V Temp Volt Tester Multimeter

Good and useful product. Good quality and functionality. Fast shipping and delivery. Good seller. Recommended 100%.

My 2024 Honda goes bonkers if the battery voltage is below 10 at start, which it has done on more than one cold occasion. The Honda fails to provide any diagnostic information (such as "you battery voltage is too low". The Honda also fails to show cabin air temperature. This meter provides both pieces of missing information, with a nice bright readout.

I bought this when my vehicle was giving me battery problems. My car is an older model (2003) so no interior thermometer, and the battery indicator on the dash lacks detailed markings. Having the ability to see the temp of the cab and battery voltage has been fantastic. I highly recommend this product for folks with an older car like mine.

Seems okay. It's actually hard to find these calibrated for Fahrenheit, going on the auction site and they're nearly all Celsius, so you end up paying a little extra for this. I was curious as to the accuracy but when I had this plugged into my bike and it was reading 12.4 I took a digital meter and double checked and it read 12.44 so you really can't get any closer then that. I figure it's a crapshoot, some are right on, some are going to be off, you know how it is when everything comes from across the pond, some work, some don't so I guess I lucked out. I didn't bother going all out checking the thermometer for accuracy, it does seem close enough anyway, It "feels" about right! I like the red and blue. It gets washed out in bright sun but, big deal, I don't need to know my voltage and the temp every minute of the day. At night it's plenty bright and I don't think over-bright either. Works good. My only complaint is I was hoping for a USB port and all I have is a plastic block where it would've gone, not the end of the world but reason enough to only give it 4 stars.

item worked right away upon connection. good product.

Easy to read and accurate. I hate the blue digits but that’s a plague on many displays. Green is much easier to read. The temperature is displayed with a leading 0 digit which is unnecessary and annoying. The human eye is not designed to see blue and red at the same time, I wish someone would tell that to the designers of so many digital displays. It’s not DROK, it’s very hard to find displays with any other combination that blue/red.

Accurate voltage and temperature sensors. I’m very happy with this meter. Sometimes temperature sensors are a few degrees off, but this one works flawlessly!

This has proven to be an excellent way of tracking my battery in the truck I own. I will also use it in a teardrop to check battery level especially when I am 'off the grid'. The thermometer is a nice bonus.
