V27D two-wire 2.5-30V DC voltmeter
Three color: Red / Green / Blue
1-30pcs, the unit price is USD3.9
30-100pcs,the unit price is USD2.9
1, the voltage meter wiring is simple, just take two lines, the table has a reversal protection, if reverse does not burn.
2, the voltage meter starting voltage is low, the red just 2.5V, green only 2.7V, Blue3.0V simply can properly measure, in line with the price of two start voltage voltmeter called the world’s lowest. This will greatly facilitate the lithium battery, 18650 battery and other users. When the voltage is lower than 3.5V, the display brightness diminishes, but does not affect the correct measurements.
3, To achieve the best measurement accuracy, the measured voltage voltmeter different according to automatically move the position of the decimal point. When measuring voltages below 10V, display two decimal places; measuring voltage above 10V, displayed after a decimal point. That is able to take care of the battery on the measurement accuracy of the user’s needs, but also take into account the need for higher voltages measured.
4, the voltage meter can be used in motorcycles, cars and other monitoring battery voltage, battery status grasp. Voltage measurement may also be used for other purposes.
