Optical technology :
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.
Digital communication :
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.
Integrated transmitter :
All data concerning calibration, history, users and measures are directly treated within the NTU sensor and transmitted via RS-485 or SDI-12.
Physical characteristics :
Compact, robust and light, the PVC sensor allows a handheld or fixed unit application.
