Pack of 2 0.28 Inch Mini Digital Voltmeter, LED Display Voltmeter, Measuring Range DC 2.4-30 V, Two Wire Voltage Tester, Reverse Polarity Protection and Accurate Pressure Measurement (Red, Blue)

• Specification: 2 pieces mini voltage tester (blue, red)
• High quality: stable performance and high precision. If the voltage is below 10V, the resolution is 0.01V. The voltage resolution above 10V is 0.1V.
• Handy and easy to assemble: small and lightweight. Reverse polarity protection and 2-wire digital voltmeter, easy to install and connect.
• Protection design: reverse polarity protection, the meter does not burn through when reverse polarity is applied, but the screen does not show anything.
• Can be calibrated:The screw on the back can be adjusted to calibration. Turn clockwise to lower the tension.

Measuring range: DC 2 4-30VVery high precision: the automatic precision setting when less than 10V is accurate to 0.01V, more than 10V to 0.1V accurate. This ensures both measurement accuracy and higher voltages.
