nke Instrumentation develops, manufactures and sells autonomous monitoring station to monitor and control water quality. The autonomous multiparameter probes are equipped with brush and teletransmission and use a wiper to protect optical sensors from biofouling. The probes measure and record the main physicochemical water parameters – the user can choose up to 7 parameters and it benefits from a fast wireless configuration thanks to a communication interface connected to the USB port of a PC. The multiparameter probes are operational as they can be adapted on multiple supports among them buoys, ladder, stake, pontoon.
WiMo: multiparameter sonde – new generation
Description - The WiMo sonde can embed four sensors to measure water parameters thanks to its smart sensor suite that benefit from real plug and play and automatic recognition. The WiMo sonde can be used manually to record profiles or via a transmission module that allows a long-term monitoring.

Wiper
Description - It is possible to add a cleaning device to the WiMo and WiMo Plus probes. This is an intelligent wiper that self-configures itself according to the sensors that are connected to the probe. It automatically detects whether the sensors need or can be cleaned and adapts its scan accordingly.
