Description
MAIN FEATURES
The water quality monitoring stations consist of a data acquisition datalogger and a multiparametric probe that allows you to measure the following chemical-physical and water quality parameters: Temperature, Conductivity, pH, Redox, Dissolved Oxygen, Turbidity e Hydrometric level.
Each measuring station can be configured as:
- fixed monitoring system with the MicroMET3 Geoves datalogger with SD Card storage system and remote data transmission
- portable monitoring system with the Geoves MicroHYD1 datalogger with SD Card storage system
The following types of multiparameter probes can be connected to each data logger:
- Multiparametric probe mod. SM6 or SM7 with 70mm diameter suitable for wells ø> 3 ": in this version up to 7 parameters can be measured, namely pH, Temperature, Conductivity, Hydrometric level, Redox, Dissolved Oxygen (option: turbidity)
- Probe in the "micro" version mod. mSM4 or mSM5 with 42mm diameter suitable for 2 ”wells: in this version it is possible to mount up to 5 electrodes or pH, Temperature, Conductivity, Hydrometric level (option: Redox).
The following options are also available:
- Measurement of dissolved oxygen with an optical sensor (replacing the one normally mounted with a polarographic cell). This solution is particularly suitable for murky and sea waters
- Measurement of turbidity
ADVANTAGES OF FIX STATION with MicroMET3
- Low consumption and power supply from photovoltaic panel
- Wireless data transmission via GPRS (or via cable on request)
- Installation without the need for electrical connections
- Excellent surge protection
- Ease of assembly and reduced intervention times
- Excellent measurement accuracy
ADVANTAGES OF PORTABLE STATION with MicroHYD1
- Powered by rechargeable AA batteries
- High operating autonomy even for continuous monitoring
- Data storage on SD Card and data in standard TXT format
- Well profiling function
- Excellent measurement accuracy and ease of use
