The WTW MultiLine® Multi 3510 IDS is a professional single-channel, wireless-ready portable meter for IDS digital sensors. Its universal measurement input reads pH, ORP/mV, dissolved oxygen, or conductivity by simply connecting the matching WTW IDS sensor — either by cable or via optional wireless modules. Digital IDS sensors are recognized automatically and carry their own calibration data, so setup is fast and error-free.

Built for both lab and field, it includes a backlit graphic display, a built-in data logger, and a USB interface for transferring records to a PC. Rugged, reliable, and cost-effective for everyday water-quality work.

Applications

Groundwater and surface-water monitoring, wastewater treatment, aquaculture, environmental sampling, and general laboratory measurement where one parameter at a time is needed.
