SIMPLE, PLUG & PLAY NITRITE MONITORING
Real Tech’s bypass High Nitrite sensor is a cabinet style instrument installed directly on a wall, railing or system backboard. Sample is supplied to the sensor from a pressurized source or alternatively, from an open-channel using an accessory pumping/cleaning system. The sensor must be connected to a Real Tech controller for operation.
EXAMPLE CONFIGURATION
- Real Controller
For affordable, user friendly operation and control - High Nitrite Sensor
For real-time continuous nitrite measurement - Real Clean System
For low maintenance automatic cleaning
Multiple sensors can be added to Real Tech’s controllers to expand water quality monitoring capabilities.
Simple to install, easy to operate, no reagents and no waiting for lab results.
