Continuous monitoring of temperature, pH and condutivity

The pH-EC-FLOW CONTROL 3000 monitors online temperature, pH and conductivity for all types of horticultural fertigation applications. It constantly measures the actual ECand pH of the flow-through in a bypass or directly in the tube. An acustic alert in case of excess or go below an adjustable limit value provides a high security for plant nutrition management and the risk of excessive or insufficient fertigation is minimized. External warning systems like signal lamps or ringing bells can be connected to the integrated relay or alternatively control functions can be carried out. The LCD provides a simultaneous display of temperature, pH and EC. The unit can easily be wall-mounted and the optional tubefitting kit enables an easy and fast installation of the probes which can simply be removed in case of calibration or replacement.
