Product Options


The INW Turbo Sensor has now been added to RS Hydro’s already extensive range of turbidity measurement equipment. The INW Turbo Sensor is a versatile device capable of measuring up to 1000 NTUs all stored in the non-volatile memory. This logger comes with built-in datalogger and Aqua4Plus software.

The INW Turbo Sensor is available for Modbus® and SDI-12 interfaces for greater flexibility, for ease of reading data real time viewing is standard and a direct read option for use with panel meters or RTU/PLC applications is available. Data is easily exported to spreadsheets and databases dependent on the users specifications.

Accuracy is guaranteed at 2% at 25°C this is assured in the vast range of applications that the INW Turbo Sensor is suitable for use in.

Finally this device comes with a variety of cable options including polythylene, polyurethane and FEP again to suit the application needs and that of the user.
