The AC current sensor is used to measure the effective value(i. e. root mean square, RMS) of AC current, and supports three working modes: wired communication with data logger, wireless communication and independent data display.

The AC voltage sensor is used to measure the effective value of AC voltage, and supports three working modes: wired communication with data logger, wireless communication and independent data display.

The 3D magnetic induction sensor is used to measure the magnetic induction intensity in a certain place, and it needs to be measured after the reading is stable.

The vector sum of the three-dimensional components is the absolute value of the magnetic induction intensity of the measurement point.

Measure the electrostatic charge.

Display the data directly by LCD.

Data logger not required 

Measure and display the sound wave form and frequency

Support 4 sound sensors work simultaneously
