    Product Information

    Three Parameters in One Instrument

    The Hach TSS Portable Hand-held Turbidity, Suspended Solids, and Sludge Blanket Level Instrument’s unique multibeam alternating light method with infrared diode system gives it a broad measuring range for both turbidity and suspended solids in one portable handheld instrument.

    It stores up to four different calibration curves for suspended solids and one for turbidity. There’s no need for constant re-calibration for different locations or types of sludge.

    The sludge blanket level can be measured by setting the units to mg/L, g/L or percent. Calibrate the instrument and then slowly lower the sensor into the clarifier. The suspended solids concentration will significantly increase as it reaches the sludge blanket level. Once the blanket

    level is reached, examine the sensor cable which is marked every meter to determine the sludge blanket level depth from the water surface.

    The instrument software automatically compensates for air bubbles to prevent its influence on the measurement. Turbidity is pre-calibrated with a calibration curve stored in the instrument. For suspended solids, each of the calibration curves can be closely adjusted to the laboratory results because each calibration curve can use up to three points per curve plus a zero value.

    The probe is made of polished stainless steel with a scratch resistant sapphire window to withstand harsh environments. Polished stainless steel helps keep particles from sticking to

    the surface of the probe. The internal memory stores up to 290 measuring values, including time, date, measurement, location, and homogeneity. Three operating modes are available—single, interval, or continuous.

    With rechargeable batteries, the Hach TSS Portable Handheld Turbidity, Suspended Solids, and Sludge Blanket Level Instrument can provide up to one month of usage in typical measuring mode and up to four hours of continuous operation. Interval mode has automatic shut off between measurements for longer operation in the field. The battery status is always visible. The operating menu is user-friendly and is displayed on an easy-to-read LCD graphic display.
