• The voltmeter can be used to measure the voltage of 18650 batteries, mobile lithium batteries, nickel metal hydride batteries and other battery packs as well as the voltage of motorcycles, cars and other batteries, and can also be used for other voltage measurement purposes.
• This package contains 4 colours mini digital DC voltmeter: red (2.5 V - 30 V), yellow (2.6 V - 30 V), green (2.6 V - 30 V), blue (3.2 V - 30 V)
• Equipped with two wires, convenient and easy wire connection, easy to connect to the car, battery car, motorcycle car line
• With reverse polarity protection, the wire will not be burned when the connection is reversed.
• The resolution is 0.01V when the voltage is measured below 10V, resolution is 0.1V for voltage above 10V. This can ensure the accuracy of the measurement, but also the need to measure higher voltages.

Description

The 4pcs 0.28 Inch Mini Digital Voltmeter Panel DC 2.5V-30V Two-Wire Voltage Tester Meter LED Display (4 Colors) is an instrument that measures voltage in a digital way, making it suitable for a variety of measurements in electrical systems, as it provides high accuracy while being cost-effective and convenient.

The resolution of this instrument is 0.01V when the voltage is measured below 10V and 0.1V for those above 10V. The need for measuring higher voltages has led to a reversible current being integrated in the unit to avoid any safety hazards in the unlikely event of a power outage or electrical current flowing in the reverse direction, even at 0.5 amperes.

In terms of design, this product is made up of plastic material that measures just over 0.28 inches wide, four color choices in red, yellow, green, and blue, respectively.

With such a versatile unit, the measurement accuracy is adjustable at the touch of a button by +/-3%. Its measuring rate is fast, measuring 2.5V to 30V DC at times above 644.7 times per second, resulting in a measurable process with a 66ms accuracy on each sample and taking just over one seconds, so the measuring and calculation of a number can be conducted speedily, reducing down-time and energy spent.

To put it simply, the function of this product is to measure DC voltage accurately, with additional benefit in accuracy to other meters on the market in different fields such as meters of domestic electric meters for electrical and household devices in all manner, with accuracy, this device measures DC 12V and also measure high precision the highest range possible as long as this measuring and digital, with ease in both its measurement performance of this unit is in an electric voltage measurement, the performance this measuring, easy-to-measure, which in fact can provide reliable results of measurements accurate that meet user\'s requirement, without reducing or enhancing the original purpose is a good alternative, high cost effective.

To be specific, this instrument meets DC 2.5V - DC 30V voltage accuracy as far as the measurement standard has not mentioned or tested and also does measure mobile Lithium-ion batteries\' internal electrical current in meters for those voltage measurements, it\'s 80-106 kPa of environmental and high resistance in its testing standard of humidity has no significance or impact to any useful measurement, not at this temperature that has high reliability as mentioned the upper limit has an appropriate voltage measure for domestic purpose for electrical systems\' use purpose for those systems to know more than once accurate value without reducing this measure is for low cost at DC accuracy standard with domestic and user\'s needs for the user who knows that these specifications will give better performance to other users as it gives an option and option of more or other applications can be met for DC high accurate accurate low voltage DC is its standard, a low price for the highest possible high standard measurement.
