0-99.9V Three Wire DC Voltmeter Head LCD Digital Display

Description Our product not can only meet the needs of battery users for measuring accuracy, but also meet the needs of measuring higher voltage.Easy to use, easy to connect, accurate, high precision and durable.When measuring the voltage below 10V, two decimal points are displayed after the decimal point; when measuring the voltage above 10V, one decimal point is displayed after the decimal point. Feature - Color: Black. - Material: Plastic+Electronic Component. - Size: 4.9 x 2.9 x 2.2cm. -Measurement Range: Red DC2.5-30V, Green DC2.7-30V, Blue 3.0-30V - Minimum Input: Measurements below minimum voltage are inaccurate or not displayed - Maximum input: DC30V (higher than this voltage is in danger of burnout) - Permissible error: less than 10V to 0.01V, more than 10V to 0.1V, 1% - Display mode: three 0.56"LED digital tube - Display color: red, green and blue are optional - Refresh speed: about 500 mS/time - Power Supply: No Power Supply - Consumption current: less than 20 mA, generally 5-15 mA - Working Temperature: - 10 ~65 -This voltmeter are easy to connect, only need to connect two wires. There is anti-protection in the voltmeter. - This voltmeter has low starting voltage, only 2.7 V for red, 2.7V for green and 3.0V for blue. This will greatly facilitate the use of lithium battery and 18650 battery users. When the voltage is less than 3.5V, the brightness of the display will darken, but it does not affect the correct measurement. - In order to achieve the best measurement accuracy, the voltmeter will automatically move decimal points according to the different measurement voltage. - This voltmeter can be used to monitor battery voltage of motorcycles and automobiles, and to master battery status in time. It can also be used for other voltage measurement purpose.Package list: 1 x Voltmeter
