Features: Multifunction Pen Multimeter - This digital pen multimeter can measure 4V-600V AC/DC voltage, 4k-40M resistance, capacitance, frequency test, switch buzzer detection, zero fire detection, etc. Easy to use - Thanks to the 4000-count backlit LCD display and flashlight function, the value can be read clearly even in dark places. Data retention function, one-touch data recording, 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. Auto Shut-Off and Audible Alarm - The pen multimeter has an auto-off function. It automatically turns off if not used for a few minutes, reducing power consumption. The sound and light alarm facilitates measurements. Easy to Carry - The compact design of the pen, convenient to use with one hand, is easy to carry and use. It is very suitable for home, school, laboratory, factory and other applications.
