Two small rectangular blue LED voltmeter gauges with transparent PVC shells

12V Digital Voltmeter Gauge Blue Light 2 Pack

SKU CH-YYH9-PRF6F

Pack of two waterproof DC voltmeters with blue LED displays measuring 5 to 28.6 V and warning below 4 V or above 28 V

  • Two-piece pack covers multiple vehicles or provides a spare
  • DC 5–30 V working range monitors 12 V systems in real time
  • Alarm flashes L L L below 4 V and H H H above 28 V
  • Waterproof PVC housing with clear window survives rain and spray
  • Operates from –10 °C to 70 °C in 10–80 % humidity

Two-Pack Voltage Gauge for Vehicles

This pack supplies two digital voltmeter gauges designed for 12 V electrical systems in cars, motorcycles, RVs and boats. Each unit operates from the measured circuit itself, requiring no separate power source, and the blue LED display remains readable through a transparent PVC shell.

DC 5–30 V Input with Alarm Limits

The gauge accepts a supply range of DC 5 to 30 V while displaying 5 to 28.6 V in real time. If voltage drops below 4 V the readout flashes “L L L”, and if it exceeds 28 V it flashes “H H H”, giving immediate warning of battery or charging faults.

Rated for Harsh Environments

Waterproof construction and a sealed smooth surface allow reliable use in exposed locations such as handlebars or dash panels. The specified operating envelope covers -10 to 70 °C, 10 to 80 % humidity and 80 to 106 kPa pressure, so the gauges suit year-round outdoor and industrial automation duties.

Questions about this item

Should I buy the single or the two-pack for my car and motorcycle?

The listing supplies two gauges, so you can monitor both vehicles at once or keep one as a spare.

What does the 28.6 V maximum reading mean when the gauge is installed?

It shows the highest voltage the display will report; above that the screen flashes “H H H” as an over-voltage warning.

How does the DC 5–30 V supply range limit where I can mount the gauge?

It operates from any 12 V vehicle system and tolerates up to 30 V input, but the display only reads up to 28.6 V.
