Astra 100AT is a modern, portable electric current transmitter with the maximum output power of 100 W, ouput voltage of 700 V and output current of 1000 mA. It is intended for being used in the frequency-domain resistivity & IP exploration of relatively deep (up to ~200 m) targets, and is controlled either manually or from any Android-operated smartphone or tablet via the Wi-Fi wireless connection. The output signal is the 100% duty cycle (for frequency-domain measurements) or 50% duty cycle (for time-domain measurements) squarewave current with the fundamental frequency values from ~0.08 Hz to ~2 kHz.

Astra 100AT is powered by an external 12V DC battery.

We have created a special website for Astra family transmitters where you can learn more about them and compare with each other.
