SOLITAX Turbidity, t-line sc, PVC With Wiper (0.001-4000 NTU), Sensor Only

Product #: LXV423.99.10000


90° turbidity measurement according to DIN EN ISO 7027. Backscatter photoreceptor to measure suspended solids accurately equivalent to DIN 37414. Time-consuming multipoint calibrations with dilution series are replaced by a single correction factor.
Fixed point installation kit or handrail mount kit must be ordered separately for immersion in open tanks. The measurement data is displayed and processed with the help of a controller.

PROGNOSYS is now available to provide confidence in your instrument readings. PROGNOSYS will monitor and display the reliability of instrument measurement values and identify when upcoming maintenance tasks are due in an easy-to-read color display.

Greater Accuracy, Less Maintenance

Hach SOLITAX sc sensors provide accurate, color-independent measurement of turbidity and suspended solids in drinking water, wastewater and industrial process applications. A self-cleaning device prevents biological growth andinterference of gas bubbles. This system’s reliable performance and full data communication capability help improve process control and reduce treatment costs associated with polymer use, digester volume, and sludge handling.

Excellent Correlation to Laboratory Analysis

SOLITAX sc sensors show an exceptional correlation to mixed liquor, settled and thickened sludge, determined in laboratory analysis. On-line measurement not only saves time on manual analysis, but also provides critical real-time TSS measurements that can be used to operate the plant more efficiently.

Fully Serviceable Sensors

Conventional turbidity and suspended solids sensors are potted and are discarded when they no longer function. SOLITAX sc sensors are fully serviceable, which often doubles the useful life of the sensor.

Easy One-point Calibration

Calibration is easy with a simple correction factor procedure. Multipoint calibration is available for nonlinear samples.

Multi-channel, Multi-parameter System

Any two SOLITAX sc sensors can be installed on one Hach sc200 Controller. The same controller can also accommodate any combination of parameters. All of Hach’s model sc sensors are “plug and play” with no complicated wiring or set-up procedure necessary.
