WTW MultiLine® Multi 3620 IDS Portable Meter

The WTW MultiLine® Multi 3620 IDS is a professional two-channel, wireless-ready portable meter for IDS digital sensors. Its two universal inputs let you measure two parameters at once — any combination of pH, ORP/mV, dissolved oxygen, conductivity, and turbidity — by connecting WTW IDS sensors either by cable or via optional wireless modules. Digital IDS sensors are recognized automatically and store their own calibration data for fast, reliable setup. Ideal for field data collection, it offers a backlit graphic display, a built-in data logger holding up to 4,500 automatic and 500 manual records, and a USB interface. Rugged and robust for demanding mobile applications. ApplicationsGroundwater and surface-water monitoring, wastewater treatment plants, aquaculture, environmental compliance sampling, and any field program that benefits from simultaneous two-parameter readings.
