The LT-73X Series are proprietary inline turbidimeters that offer ranges from 0.001–1,000NTU with ultra-low resolution. This sensor has a unique flat surface distal end in a quartz glass plate, allowing for extending cleanliness and easy maintenance & prevention of air bubble interference. The ST-73X Series are EPA 180.1 compliant as they utilize warm white LED light sources for optimal accuracy and performance in a wide range of turbidity water samples. It also uses 90º surface scatter configuration, offered in two flow assembly installation formats (FR-100 Flow Reservoir or FT-100 Inline Tee). Powered by a 24VDC/2W power supply and offers both 4–20mA & RS-485 Modbus output signals. When clean, the unique Pyxis Lab® sensor design offers a calibration stability of <0.02NTU for up to 1-year of operation with no need for calibration. Additionally, the ST-73X can be wirelessly accessed via Bluetooth® for Diagnostics, Cleaning, & Calibration on uPyxis® when used with the MA-CR Bluetooth® Adapter.
