Multiparametric analyser Aquamaster 345

Multiparametric analyser designed for on site measurements of all most important chemical and physical parameters useful to characterise the quality of a water. It can be used both for spot measures and for long term measurements.
Mod.345 AQUAMASTER is composed of a surface unit and an immersion probe.
The surface unit is a splash-proof (IP-56) plastic box provided with a soft carrying case with handles allowing hands-free operation. It inclucles a sealed compartment for the rechargeable battery pack and line power supply / battery-charger. If needed the instrument can be also operated with an external 12V battery. A waterproof membrane keyboard allows an easy programming and parameters selection. All data can be read simultaneously on back-lighted LCD.
The instrument can be operated as a real-time multimeter or as a data logger, storing data at intervals between 10 seconds and 24 hours.
A serial interface RS-232 is provided to connect the Model 345 to any Personal Computer or other suitable device to retrieve data stored in memory, A simple WINDOWS software is available to create data disk files and to format data or reviewing and printout. Model 345 can be also connected to any existing data transmission system (MODEM or VHF radio-link) for long distance connection.
The probe is an all-stainless steel cylindrical container (IP65) housing all sensors, cells and electrodes with the related electronic circuits.
All signals are amplified scaled and converted in digital form locally inside the probe.
The electric connection cable is internally reinforced with a Kevlar core and also acts as a supporting rope. A submarine multipolar connector allows to separate the probe from the cable.
All electrodes and cells requiring frequent substitution and service, are easily removable without necessity of dismounting the probe body.
Special features allow a very flexible operation: back-lighted display allows reading in critical conditions; large memory of 128Kb allows data acquisition and recording of date and place of measurement; possibility to maintain in charge the battery when instrument is not used, or recharging it by using a car battery when needed; possibility of data interchange between users working with different probes; possibility to use the instrument in fixed monitoring stations for environmental surveillance; possibility of data transmission via MODEM of VHF radio -link
Mod.Aquamaster 345 can measure the following parameters: pH, ORP, Conductivity, Dissolved Oxygen, Salinity, Surface Temperature and Temperature in depth, Barometric pressure, Depth, Turbidity.

Multiparametric analyser Aquamaster 346

Multiparametric analyser specifically designed for on site measurements of all the most important chemical and physical parameters useful to characterize the quality of water.
The system is suitable to measure in fresh water (rivers and lakes), salt water, wells and clarified wastewater.
The complete measuring system includes the multiparametric probe, (Mod.346/P - complete version that can include sensors of pH, ORP, ISE, Conductivity, Turbidity, Dissolved Oxygen, Pressure, Temperature and the stirrer - or Mod.346/PS simplified version that can include sensors of pH, ORP, Conductivity, Dissolved Oxygen, Pressure, Temperature and the stirrer) the cable with sealed connectors, the instrument Mod.346/SU (datalogger c/w data transmission system via RS232 serial interface or via radio or via Modem GSM) or the instrument Mod.346/IU (pc interface c/w RS232 serial link or Modbus); PC or PLS (these last two are to be supplied by the customer).
The multiparametric probe is available in two different versions: Mod.346/P is the complete version and can include sensors for pH, ORP, ISE, conductivity, turbidity, dissolved oxygen, pressure, temperature and the stirring motor; Mod.346/PS is the simplified version and can include sensors for pH, ORP, conductivity, dissolved oxygen, temperature, pressure and the stirring motor.
The stirring motor is required when the probe is intended to measure in still water or when the probe includes the dissolved oxygen sensor and the sample water flow on the sensor is lower than 0,5 cm/sec.
The multiparametric probe Mod.346/P- in both versions is made of a stainless steel cylinder, AISI 316, housing all sensors, cells and electrodes with the related electronic circuits.
All signals are amplified, scaled and converted in digital form locally, inside the probe.
All electrodes and cells requiring frequent substitution and service, are easily removable without necessity of dismounting the probe body.
All calibration data are stored inside the probe so that different probes can be connected to the same Surface Unit. The Surface Unit Mod.346/SU can be connected to different probes without the need to perform any calibration or other configurations, and it automatically recognizes the probe arrangement.
Data transmission within probe and surface unit is operated via RS 485.
The electric connection cable is internally reinforced with a Kevlar core and can also act as a supporting rope. A submarine multipolar connector allows connecting the probe to the cable. The cable connector can optionally be connected to a stainless steel rope for probe lifting.
Aquamaster 346 can mesasure the following parameters: pH, ORP, ISE Conductivity, Dissolved Oxygen, Salinity, Surface Temperature and Temperature in depth, Barometric pressure, Depth and Turbidity.
