Continuous monitoring of physical and chemical properties of water is performed with multi-parameter
probes DS5X by OTT Messtechnik GmbH, that measure the following parameters: water temperature,
dissolved oxygen, pH, redox potential, specific electric conductivity, chlorophyll, turbidity, as well as ammonia, nitrate and chloride content. The probes have a self-cleaning system that removes dirt from the
electrodes before each measurement, which guarantees maximum reliability of tests. The probes can test 15
parameters at the same time. Results are collected in the probe's memory and their interval may be
programmed at one's discretion.
