Features 【Multifunction】This pen type digital multimeter can perform 4V-600V AC/DC voltage measurement, 4kΩ-40MΩ resistance, capacitance, frequency test, switch buzzer detection, zero fire detection, etc. 【Easy to Use】Thanks to the 4000-count large backlit LCD screen and flashlight function, the value can be read clearly even in dark places. Data retention function, save data with one key, convenient for data reading. 【Non-contact Measurement】The digital multimeter supports NCV non-contact voltage detection, which can distinguish between the neutral line and the live line to avoid the risk of electric shock. Safe and reliable. 【Automatic Shutdown】The pen multimeter has an automatic shutdown function, which will automatically shut down if there is no operation within a few minutes, reducing power consumption. The sound and light alarm makes the measurement easier. 【Wide Application】Compact pen design, convenient for one-handed use, easy to carry and operate. It is very suitable for home, school, laboratory, factory and other applications.
