The NT-4S is a fully featured core-alignment fusion splicer with a precision ceramic V-groove and a ceramic fibre pressure hammer. A five-in-one multifunctional clamp handles all common fibre types, the 4.3-inch capacitive touch screen with button/touch dual control keeps operation simple, and a 5200 mAh lithium battery delivers more than 340 splice-and-heat cycles. A modular design allows Bluetooth, IoT and other functions to be added as required. Seismic, waterproof and drop-resistant, it adapts to the toughest field conditions.
