High-precision Multi-parameter Online Water Quality Monitor

I. Applications

Semiconductor, nuclear power, power plants, chemical and petrochemical, steel, metallurgy, papermaking, cement, food and beverage, pharmaceutical wastewater, tap water, environmental protection, fire fighting, aquaculture and research institutes.

II. Controller Features

1. Multi-parameter: dissolved oxygen, pH, ORP, conductivity and temperature can be combined freely.

2. High-resolution colour touch screen: 800 × 480 graphic dot matrix with a Chinese menu, convenient and real-time operation.

3. Curve display: measurement results are shown as real-time digits together with a trend curve.

4. Multi-channel configuration: up to 4 different sensors can be connected, saving cost for the customer.

5. Large-capacity data storage: 1.5 million data records with historical curve query.

III. Electrode Features

Trace dissolved oxygen electrode

1. Based on Clark electrode technology: designed specifically for the measurement of trace (ppb-level) oxygen in water and gases.

2. High precision and high sensitivity: detection limit 0.001 μg/L, resolution 0.001 μg/L.

3. Fast response: generally only 3 minutes from air-saturated oxygen concentration to the μg/L level.

4. Long-life electrode: reduces the cost of frequent electrode replacement.

5. Long maintenance interval and low-cost consumables: electrode maintenance only every 6–8 months.

High-precision pH electrode

1. Cylindrical sensitive membrane: wide measuring range, resistant to breakage.

2. Special formulation: better suited to industrial applications.

3. High precision and high sensitivity: resolution 0.001, accuracy 0.01.

4. Long electrode service life.

ORP electrode

1. Cylindrical sensitive membrane: wide measuring range, resistant to breakage.

2. Special formulation: better suited to industrial applications.

3. High precision and high sensitivity: resolution 0.1 mV, accuracy 1 mV.

4. Long electrode service life.

High-precision conductivity electrode

1. Stainless steel electrode: resistant to temperature and pressure, long service life.

2. High precision and high sensitivity: resolution 0.0001 μS/cm, accuracy ±1.0 %.

3. Automatic temperature conversion: corrects the conductivity measurement and converts the reading to the reference temperature.
