Product Specification
DDM-200/DDM-200C Series Conductivity/Concentration Transmitter
This product is one of the conductivity transmitter, protection class IP65 / IP68, can be installed directly into the formula, suitable for all occasions need to measure conductivity, such as water treatment, aquaculture, marine environment monitoring, CIP and other industries.
Conductivity/Concentration Transmitter Typical applications
● Pure water / drinking water / surface water / variety of water supply / industrial sewage.
● Acid, alkali and salt solution / chemical reaction process / industrial manufacturing process.
● Soilless cultivation / flower greenhouses / aquatic farming / swimming pool.
● DDM-200C: concentration measurement for acid alkali and salt solution.
Conductivity/Concentration Transmitter Instrument characteristics
● Easy connect to PLC, industrial computer, controller, data logger or touch screen for online monitor and control.
● Strong anti interference, fast response.
● The probe use gold plate VP header for plug connection. Threaded fastening, very easy to replace the probe.
● Easy mounting. The 3/4” NPT thread is easy for pipe and tank mounting. The probe can be also separated with the display header, connect by cable.
