WTW MultiLine® IDS Portable Meters

MultiLine® IDS portable water quality meters are robust with a IP 67 waterproof rating and available in wireless sensor configurations.

The Intelligent Digital Sensors (IDS) – combine proven measurement technique with additional advantages. The proven electrochemical WTW sensors are equipped with advanced measurement electronics the that distinctively store their serial number and calibration records for immediate operation.

For wireless configuration place the included wireless module on the IDS plug head sensor, confirm the connection – done! Put the module on a desired sensor or use a separate one for each sensor. No cables, no tugging, and full flexibility.
