5-Parameter Online Water Quality Monitor

5-parameter online water quality monitors,the unique patented design makes this product have lower failure rate, lower maintenance and higher cost performance than similar products. All sensors are RS485 communication interfaces, standard Modbus protocol.

Easy installation: simple structure, easy installation, firm and reliable.

Insulation impedance: under normal circumstances, when the instrument is off the circuit state, the impedance meter prescribed by the state is used to measure the insulation impedance between the power input line and the housing should be more than 20MΩ.

Insulation strength: between the power supply line and the housing of the instrument can withstand 50Hz, 1500V, current limit 5mA, lasting 1min, no flaring and breakdown phenomenon.

Average trouble-free continuous operation time: The actual water sample was used to run the instrument continuously for 2 months, record the total running time (h) and the number of failures (times), and calculate the average trouble-free continuous operation time (MTBF)≥720h/ time.

• Dissolved oxygen/temperature electrode: small drift, fast response, short polarization time; No need to replace the dissolved oxygen film and electrolyte; Not sensitive to dirt, almost unaffected by flow rate; Direct calibration in the air without zero calibration; Corrosion-resistant housing, waterproof rating IP68 for long-term underwater work.
• PH electrode: industrial grade composite pH electrode, suitable for harsh working environment; Compared with double salt bridge design, the electrode has long service life; PT1000 temperature compensation, accuracy up to ±0.1℃; Corrosion-resistant housing, waterproof rating IP68 for long-term underwater work.
• Conductivity electrode: quadrupole electrode design precision, high accuracy, good linearity, wide range; Electrode constant is very stable, not affected by polarization; Corrosion-resistant housing, waterproof rating IP68 for long-term underwater work.
• Turbidity electrode: with self-cleaning function, remove attachments in water samples; Digital modulation filter technology to eliminate the influence of ambient light; Long life infrared LED light source, up to more than 10 years; Corrosion-resistant housing, waterproof rating IP68 for long-term underwater work.

5-parameter online water quality monitors, mainly used for water transmission channels, reservoirs, lakes, landscape water, pipe network water quality automatic continuous monitoring.
