Water quality sensors

DISOLVED OXYGEN / TEMPERATURE : Optical technology based on luminescent optical technology. This sensor is approved by the ASTM International Method D888-05. Accurate measures in all situations and especially in very low oxygen concentrations. Body in Stainless steel or TITANIUM.

PH / ORP / TEMPERATURE : Digital technology, combined electrodes, calibration data inside the sensor.

liste_arrow CONDUCTIVITY / SALINITY / TEMPERATURE : The electrode works with a technology in 4 electrodes: an alterning current of constant-voltage is established between a primary’s pair of electrodes in graphite. The secondary’s electrodes in platinum allow of regulate the voltage imposed to primary’s electrodes to reflect of the fouling. The voltage measured between the primary’s electrodes is in function of the resistance of place and so, of the conductivity.

INDUCTIVE CONDUCTIVITY / SALINITY / TEMPERATURE : A ring-type coil is excited at fixed intervals and the response is retrieved on a second coil, which is linked to the excited coil. The connectivity between the coils (determined by the degree of conductivity) takes place via the conducting solution.

Wireless logger GSM/GPRS and digital water quality probes

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

ORP POTENTIAL / TEMPERATURE : The sensor incorporates a reference electrode, used for ORP measurements, such as Ag/AgCl in saturated KCl electrolyte plasticized “PLASTOGEL”®. The electrolyte communicates directly with the external environment without interposition of capillary or porous.


Data loggers with wireless communication

The sensors connect to the LOGV4 loggers series on its RS485 Modbus input. The communication on-site with the logger is done safely by radio, from the bank or boat. This allows you to connect, configure the sensor and retrieve data locally. Several water quality probes can be connected to the same loger using a Y-connector. An additional external battery pack (Lithium battery, or rechargeable lead battery) can also be added to the installation.


Remote monitoring by 2G / 4G (LTE-M / NB-IoT)

The loggers will send all its data to the SCADA according to the chosen transmission mode. You can choose the optional communication card 2G/4G (LTE-M / NB-IoT). By choosing a logger with an integrated modem, you can send your data directly to our web platform, or any other server with your SCADA
