Product introduction:
This meter is used to measure the voltage of the DC power supply and has the function of high and low voltage alarm; it can be directly connected to the power supply to be measured without power supply. There are two buttons at the back of the meter to set the alarm voltage value; the pressure measurement range of the meter is 3.6V- 50V, the alarm setting range is 4.5V-50V; it has high-precision pressure measurement, and the accuracy can reach 0.1V, which is comparable to the imported meter. The digital tube uses a high-brightness digital tube, and the default is red. If you need other colors, please leave a message and let us know before placing an order.
