Continuous inline monitoring of oil contamination and UV-absorbing substances in water and process media for industrial, environmental, and water treatment applications.
The LAS inline turbidity sensor operates on the principle of light absorption to measure suspended solids in liquids. A light beam passes through the process medium, while a detector positioned opposite the light source measures the transmitted NIR light intensity. The detected NIR signal varies according to the turbidity of the liquid.
The signal converter processes the measured light intensity and calculates the turbidity value. The sensor is compatible with the C1 signal converter or, alternatively, the C2 signal converter.
The LAS sensor combines low maintenance requirements with a wide measuring range, making it ideal for continuous operation and long service life. Thanks to its metal-fused sapphire windows and the food-grade TH Varivent measuring cell, no additional window seals are required. This hygienic design eliminates dead spaces and prevents contamination around the measuring windows, making the sensor especially suitable for demanding hygienic process applications.

The Model C1 Signal Amplifier is compatible with most optical sensors from the Monitek and Chemtronic product ranges. System programming and calibration are carried out via a PC or laptop using intuitive menu-driven software. Calibration can be performed with one or multiple reference samples. All configuration settings and calibration data can be securely stored on the PC’s hard drive for backup and future use.
The Model C2 transmitter precisely processes the measurement signals from the AP2 turbidity sensor and is ideally suited for monitoring and optimizing industrial processes.
Equipped with a TFT graphic display, 0/4–20 mA analog output, programmable switching output, and automatic self-diagnostics, it is designed for reliable operation in demanding industrial applications.
