About the Zonge International NT-20 TEM Transmitter
The NT-20 is Zonge International's dual-mode battery-powered transmitter, purpose-built for NanoTEM and ZeroTEM survey methods where very fast current turn-off times are essential for resolving shallow, near-surface time-domain electromagnetic response.
It's used alongside a Zonge GDP-series receiver as a complementary transmitter/receiver system, weighing around 5 kg without batteries and delivering up to 20A peak output current, with input voltage requirements of 10–13V (NanoTEM mode) or 10–30V (ZeroTEM mode).
