346 - Multiparametric Probe

The Leading Instrument for Quality Water Survey

  • 346 Multiparametric ProbeBattery-powered with long autonomy
  • Suitable for fresh waters, sea water and wastes
  • Internal data-logger with PC interface
  • Probe tested at 200mt depth
  • 12 parameters with real-time display

Model 346 Aquamaster has been specifically designed for the measure of the most important electrochemical parameters of a water. It allows the continuous monitoring of wells, basins, and all the other check points relevant for the quality of a water.

The system allows long-distance data transmission so that the continuous monitoring can be operated from remote laboratories or control rooms even with long periods data collection.

The probe diameter is 48 mm, so it can be easily used in artesian wells while the included sensor are easily replaceable. The body is made of Stainless Steel, so the probe is suitable also for the use in sea water and wastewater. The probe can be immersed down to 200 m depth.

The datalogger is included into a sealed housing (IP56 protection degree), together with the rechargeable battery. A GSM modem or a radiotransmitting device can be installed in the same housing. Should the power supply not be available at the point of installation, the instrument can be powered through a solar collector.

A specifically designed program allows to control many Aquamaster monitoring points through a PC. Data are collected and stored on a continuous basis or at programmed intervals and are stored on disk so that they are available to be processed.
