Wireless innovation

WTW have recently released innovative new wireless IDS Sensors. No cables, full flexibility, space saving, and with absolutely secure data transmission: The new IDS system from WTW is now available with universal wireless modules for IDS plug head sensors for pH/ORP, conductivity, dissolved oxygen, and turbidity. WTW has reengineered its IDS meter portfolio and extended the IDS electrode portfolio with new pH/ORP electrodes with plug heads. Up to three parameters can be measured and stored simultaneously (depending on the meter). With state-of-the art power saving technology for long operation times and a range of up to 10m, applications in the laboratory, in a plant, or in the field could easily be solved.
