The Turbi-Tech 2000LS Sensor is designed to monitor the levels of Suspended Solids or Turbidity typically found in Final Effluent from municipal and industrial wastewater treatment plants. It is also great at monitoring solids in the intake to both effluent and drinking water treatment processes.
Monitoring of these key parameters requires sensors that are reliable and accurate, the Turbi-Tech 2000LS meets this requirement perfectly. The large optical surfaces and sample volume ensure that the information provided by the sensor is both representative of the process and tolerant of fouling. In addition, the sensor incorporates a self cleaning mechanism that ensures the optical surfaces are kept clean at all times. The cleaning system is designed to avoid problems with ragging and does not smear the optical system.
The Turbi-Tech 2000LS Sensor employs infrared light at 860 nm using the 90º Light Scatter principle in accordance with ISO7027 (2000). The cleaning process is automatically initiated by the 7300w² Monitor at a user determined frequency. The cleaning process takes only 90 seconds, which means that the sensor is available for 99.5% of the time with a 5 hourly cleaning cycle.

| Measurement Characteristics | |
|---|---|
| Principal of Operation | Light Scatter ISO 7027 Compliant |
| Wavelength | 860 nm Infrared |
| Accuracy | Better than +/-5% of reading on real sample |
| Resolution | Dependent on range setting, typically +/-2% of reading |
| Response Time | 0.5 seconds damping provided by monitor |
| Flowrate | Not affected by flowrate, avoid deadspots and extreme turbulence |
| Units | User Selectable mg/l, g/l, ppm, %SS, NTU |
| Maximum Range | 0-500 FTU, extended range of 0-1,000 FTU available |
| Minimum Range | 0-50 FTU |
| The actual measuring range will depend on the nature of the sample being monitored, for processes normally operating at 10,000 mg/l or more should consider use of the HR version of this sensor. Processes that use carbon will provide higher than expected readings and the HR version of the sensor should be used. |
