MULTI PARAMETER PROBE - P230 SMP

Description: The multi parameter probe SMP allow the simultaneous and continuous measuring of the most common surface or groundwater physical–chemical characteristics.
Electrodes: The electrodes are exchangeable and are selected from the high accuracy, long-term stable sensors available in the market. The probe can include the following sensors: pH-value, electric conductivity, redox-potential, dissolved oxygen, temperature and water level.
Internal data-logger: The probe electronic management is entrusted to an internal data logger that achieve among other the following functions: signal acquisition and A/D conversion, data storage and/or data transmission to a remote station located at the ground or at some distance. The probe configuration and all functionalities can be modified locally or remotely programmed using the user friendly Olimposw software package.
Data downloading: Digital output for local connection to external data logger, Laptop or remote data transmission using any standard data transmission device. The ASCII format allow to import the data in Excel or any other standard package.
Operation: The probe can be submerged up to water column of 30.0 m, it’s connected to the surface control unit using a self-supporting cable for power supply and data transmission. Optionally special transducer cable with barometric pressure vent
Housing: The probe body is realized in special AISI 316 stainless steel that warranty high mechanical robustness and high stability on aggressive environmental conditions.
