Ponsel Turbidity Digital Sensor Bare Wire

Compact & Robust

The measure principle is based on IR nephelometry / 850 nm. The sensor can be calibrated with a formazine standard solution.
The NTU sensor integrates a low-cost optical technology, with a very few maintenance and no consumables.

The PONSEL sensor can be connected to any types of transmitters, display units, controllers or data loggers with Modbus RS-485 or SDI-12 inputs. The optical sensor saves its calibration data for better measures management.

All data concerning calibration, history, users and measures are directly treated within the NTU sensor and transmitted via RS-485 or SDI-12
