Five small rectangular digital meters with red-blue LED displays

5PCS 0.28" Volt Amp Meter DC 100V 10A Waterproof Red-Blue measurement tool

SKU CH-9H3S-2TDC0

Pack of five 0.28-inch dual-colour DC meters measuring 0–100 V and 0–10 A with built-in shunt for 4–30 V systems

  • Sports TeamNO
  • 28" dual-colour display shows volts and amps together
  • Measures DC 0–100 V for battery and system monitoring
  • Built-in shunt handles DC 0–10 A without extra parts
  • Operates from DC 4.5–30 V supply rail
  • Compact 48×29×26 mm panel fits tight spaces

0.28″ dual-colour volt/amp meter

This pack contains five compact DC meters with a 0.28″ red-and-blue LED display. Each unit measures voltage from 0 to 100 V and current from 0 to 10 A with 1 % accuracy. The integrated shunt allows direct connection without an external resistor. Designed for automotive, motorcycle or electric-vehicle battery monitoring and general low-voltage DC measurement tasks.

Check supply voltage and wiring before use

The meter itself requires a working supply of DC 4.5–30 V and draws about 20 mA. Supplying more than 30 V will damage the device. Ensure the circuit under test stays within the 0–100 V and 0–10 A ranges. The three-wire harness provides power, voltage sense and current sense connections; verify polarity and wire order against the supplied diagram before energising.

Waterproof panel mount with integrated shunt

The housing measures 48 mm × 29 mm × 26 mm and is rated for operation from –10 °C to +65 °C. Its sealed construction resists moisture in vehicle and marine environments. The built-in shunt means no extra components are needed for currents up to 10 A, simplifying installation in tight panels. Refresh rate is approximately 300 ms per reading, giving a steady display for slowly varying loads.

Questions about this item

What comes in the box and does it need an external shunt?

The pack contains five 0.28" red-blue digital volt-amp meters with an integrated shunt, so no external shunt is required for currents up to 10 A.

Which working-voltage version should I pick for a 12 V or 24 V vehicle system?

The meter operates from DC 4.5–30 V, covering both 12 V and 24 V automotive electrical systems without any version change.

What does the 1 % (±1 digit) accuracy mean for real readings at 12 V and 10 A?

At 12 V the voltage reading can vary by about 0.2 V, and at 10 A the current reading can vary by about 0.1 A.
