Advantages
- Digital sensor, RS-485 output, support Modbus.
- Light path: 254nm, reference light, can effectively eliminate turbidity effects.
- Adopt advanced cold light source UV LED, with long life and small drift.
- The probe is directly immersed in measurement without sampling and pre -processing.
- With automatic cleaning function, it can reduce maintenance.
- The fastest 10 seconds response (T90).
- Low operation costs, rarely maintain daily maintenance, cost -effective.
- No reagent, no pollution.
- Power supply positive and negative anti -connection protection.
- RS485 A/B -end error connection protection.
Product Description
The organic matter dissolved in the water body has a specific absorption peak on the ultraviolet wave band. By measured the dissolved organic substances absorb the ultraviolet light of 254nm wavelength, thereby accurately measure the specific content of dissolving organic pollutants in the water.
