DROK Waterproof Digital Voltmeter Voltage Review

I bought two and they will work for their intended purposes. Need a meter to monitor 6V car battery during winter storage. Also, a meter is needed to ensure the boat's battery is charged while underway. bright and easy to read. The gauge is small and easy to hide, although the latches on the ends are very rigid and difficult to attach when the gauge is mounted on a dashboard or panel. Accuracy within 0.1-0.2V tested on a Fluke flow meter. Proper minions would get 5 stars.

I bought a Droc Digital Voltmeter (3-30 VDC) to install on the control panel of my Ariens self-propelled lawnmower. Installation is easy and complements the overall look. The sensor works great and doesn't seem to be affected by vibration (caused by the engine or my uneven lawn). Although the counter says it's waterproof, I cover his face with duct tape during the machine wash, just in case. I like a clean car. So far I'm absolutely satisfied with the cost/ease of installation and the look of…

I need a voltage display screen for a magnetic battery switch. so i went ahead and got this one. very surprising, appears to be of excellent quality. The insides are well sealed. It fits almost perfectly in the original dashboard slots. However, the last slot I had was right under the key switch. This LED display is great during the day and very bright at night. I can even read it from the outside through the double charcoal tint. I may have to move it because it creates a bit of brightness in…

Blue 3 digit voltmeter works fine. But after a week, the plastic sticker on the front deformed and peeled off. I contacted DROK to replace the plastic stickers as the installation took an hour and I don't want to replace the whole voltmeter. I don't know why it deformed. It could be high humidity. I have requested some replacement stickers in case this happens again. That issue aside, the voltmeter works very well and looks good. As a note to others, if you use a switchable positive relay you…

I needed a voltmeter for my 6 volt farm tractor. While on a tractor this voltmeter will be exposed to rain so I needed a voltmeter that was waterproof. Based on testing with a multimeter the tractor doesn't start at 5.3 volts and with the charger on it reads around 8.5 volts so the range I'm trying to read is quite small and the analog meter doesn't have enough resolution. Also, I had to remove the power supply from the 6V battery. The specs say this voltmeter works up to 3 volts so it was…

Revain sells several DROK digital readers. This is a small three digit blue LED display that measures DC voltage. This is a two wire module (red +V and black ground) so the measured voltage also powers the LED display. The display removes power from the circuit to light the LEDs (5 to 20mA). The LED digits are 11mm high and bright enough to be read from several meters away. Although it is advertised as a 12 volt battery meter, the product description states that the operating/measurement…
