Feature: Made of high-quality materials, it is durable, wear-resistant and can be used for a long time. This type of resistance meter can self-test within 0.5 seconds and start up immediately, which is easy to use. The resistance range is 0.01-200Ω, and the measurement accuracy is high and the rate is fast. With warning light, the beep and NOISE symbols flash, and the anti-interference ability is strong. Low power consumption, long battery life and long life. With fastening screws, it is safe and reliable, and it is easy to replace the battery.
