The WTW MultiLine® Multi 3630 IDS is the flagship three-channel, wireless-ready portable meter in the MultiLine family. Its three universal inputs let you measure up to three parameters simultaneously — any combination of pH, ORP/mV, dissolved oxygen, conductivity, and turbidity — using WTW IDS digital sensors connected by cable or optional wireless modules. IDS sensors are recognized automatically and carry their own calibration data.

Designed for serious field and lab work, it features a color graphic display, a built-in data logger (up to 4,500 automatic and 500 manual records), and USB interfaces. Rugged, wireless-ready, and future-proof.

Applications

Multi-parameter groundwater and surface-water surveys, wastewater treatment monitoring, aquaculture, environmental compliance, and research where simultaneous three-parameter measurement saves time in the field.
