The Extech GX900 True RMS MultiMeter transmits key electrical readings to Android™ mobile devices. The integrated Bluetooth™ connects with most Android devices to transmit readings for remote viewing. The GX900 transmits values up to 30ft (10m) away.

The low pass filter conditions the inputs to provide accurate voltage and frequency readings on motors, drives and other large electrical equipment that generate electrical noise. The datalogging stores up to 2500 readings with date and time stamp. The Windows compatible software is included for wireless transfer of logged data or recording data in real time.
