Overview

What this product is built to monitor

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. This allows 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.

Reverse Osmosis & Desalination

Reverse Osmosis (RO) desalination is a cutting-edge water treatment process. It removes dissolved salts, minerals, and contaminants by forcing water through semi-permeable membranes under high pressure. Additionally, RO has become a critical solution for transforming seawater and brackish sources into usable water. Applications include municipal, industrial, and commercial grade systems.

Pyxis Lab delivers advanced inline sensor technology, smart analytics, and plug-and-play monitoring systems. Designed specifically for the challenges of RO desalination, our innovative solutions empower operators with real-time insights. In addition to reliable data to drive system efficiency, protect assets, and achieve superior water quality at every stage of the process.
