Waikato researchers unlocking keys to climate change hidden in the drip water from inside New Zealand’s deepest caves, have developed a new device which is now being used by researchers around the world. The device, called Syp, is now being manufactured in Hamilton and marketed by Waikato Scientific Instruments, a spin-off from the University’s commercial arm WaikatoLink. Syp can automatically collect up to 58 predefined water samples over 12 months, all powered by AA batteries. Without Syp, researchers would have to make multiple trips to remote caves that can take hours or even days to reach on foot, making it challenging, time consuming and costly.
