0.00 - 20.00mg/L Online Luminescent Dissolved Oxygen Analyzer / Meter - LDO10AC


1. Application

Continuously monitor DO in municipal and industrial wastewater treatment process

• Sewage plant

Aeration tank,collection well,aerobic digestion tank,outlet

• Power plant

Water/wastewater treatment process

• Surface water

Rivers,Lakes/Streams,ocean

• Aquaculture

Sea cages, land-based pond

• Other industries

Food industry,Chemical industry


2. Features and Benefits

• Based on the innovative principle utilizing fluorescence to measure dissolved oxygen, the sensor does not require frequent replacement of membranes and needs low maintenance.

• The Measurement does not consume oxygen, stir or flow is not required, and unaffected by H2S,pH, K+, Na+, Mg2+, Ca2+, NH4+, Al3+, Pb2+, Cd2+, Zn2+, Cr, Fe2+, Fe3+, Mn2+, Cu2+, Ni2+, Co2+, NO3-, SO4-2, S-2,

PO43+, Cl-.

• Digital sensor has good anti-interference performance and high stability, and the cable length is available in hundreds of meters.

• Connections between the sensor(s) and the transmitter are “plug and play”, and multi-channel transmitter operates either 1 or 2 sensors.

• Modbus RS485/RS232 or Profibus DP network connection for data transmission is Optional

• The menu is available in Chinese or English.

• 3 Relays with programmable hysteresis povide high-limit alarm, low-limit alarm or timer.

• A built-in data logger with the capacity to store data for up to 10 years collects measurement data at user selectable intervals.
