Hach TSS Portable Hand-held Turbidity Suspended Solids and Sludge Level System Complete TSS Portable Hand-held Turbidity Suspended Solids and Sludge Level System; includes meter probe rechargeable batteries charger for rechargeable batteries with four plug adapters manual quick start guide and carrying case. • Three Parameters in One Instrument • Multiple Calibration Curves for Convenience • Easy Sludge Blanket Levels • Air Bubble Compensation for Accuracy • Durable Materials for Long Life • Product #: LXV322.99.00002 Three Parameters in One Instrument The Hach TSS Portable Hand-held Turbidity Suspended Solids and Sludge Blanket Level Instrument's unique multi-beam alternating light method with infrared diode system gives it a broad measuring range for both turbidity and suspended solids in one portable handheld instrument. Multiple Calibration Curves for Convenience 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. Easy Sludge Blanket Levels 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. Air Bubble Compensation for Accuracy 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. Durable Materials for Long Life 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.
