Where flexibility is needed with water monitoring a multiprobe can replace multiple instruments and save time in the field to help reduce overall monitoring costs. With highly stable sensors, wireless data capabilities as a portable or integration with systems for long-term installation, water monitoring is becoming quicker and more efficient.

Whether spot checking a tank or conducting long-term monitoring, using a multiparameter instrument over several single-parameter instruments can reduce time in the field and lower costs. Coupled with an easy access to data, water testing becomes drastically more efficient and economic.

In-Situ’s Aqua TROLL 500 Multiparameter Sonde is a wireless-enabled multiprobe that streamlines data collection while reducing the number of hours needed in the field. Save time with auto-configuration and fast sensor response that speeds up sampling, while automated data collection eliminates the need to record data in field logs.

The flexible multiprobe works for spot checks and low-flow sampling as well as long-term deployments. The anti-fouling wiper and titanium corrosion-resistant housing help protect data quality in harsh conditions.

Real-time data collection

The Aqua TROLL 500 can store collected data either in a display device or internal memory, giving more accurate readings than can be made in samples that are removed from their source. It connects into telemetry systems for long-term monitoring, and it also comes with wireless-enabled data collection for surface water spot checks.

In-Situ’s VuSitu Mobile App records data directly from the probe to your mobile device when using the instrument as a handheld. For long-term monitoring, In-Situ’s HydroVu platform provides 24/7 online data access.

The customisable sonde comes with sensors that include:

  • RDO Optical Dissolved Oxygen
  • Actual and specific conductivity
  • pH/ORP
  • Salinity
  • Total dissolved solids (TDS)
  • Resistivity
  • Density
  • Turbidity
  • Temperature and pressure
  • Ion Selective Electrodes

Built to perform

Like all of In-Situ’s high-performance probes, the Aqua TROLL 500 is built for reliability and ease of use. The rugged design includes ultra-stable, interchangeable wet-mateable sensors that lower the total cost of ownership while the LCD readout displays sensor health and connectivity.

The Aqua TROLL 500 works in a wide range of applications such as surface water spot sampling and profiling, remote monitoring via telemetry, long-term drinking water, wastewater or stormwater monitoring, aquaculture and for wired or wireless water quality networks.
