Digital physicochemical Technologies

liste_arrow 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.

liste_arrow 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.

liste_arrow 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

liste_arrow 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.

liste_arrow 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 loggers LOGV3 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.


GSM/GPRS Communication

The loggers with integrated communication card send data via GSM / GPRS to the supervision or on Thresholds are configurable, as well as the frequency of sending the reports.
