In-Situ SmarTROLL Multiparameter Meter

Hold the future of water quality monitoring in your hand.  The SmarTROLL Multiparameter (MP) Handheld combines industry-leading water quality sensors with revolutionary smartphone mobility.  The intuitive iSitu® Application eliminates training time and runs on your iPhone®, iPod touch®, or iPad® device.  The SmarTROLL MP simultaneously measures 14 parameters:

  • Chemical parameters: Dissolved oxygen (optical sensor), conductivity (actual and specific), pH, ORP, salinity, total dissolved solids, resistivity, and density
  • Physical parameters: Air and water temperature, barometric pressure, water level, and water pressure

Simply connect the SmarTroll MP Probe to a battery pack, launch the iSitu App, and start reading results.  No warm-up time or tedious setup.  The iSitu App guides you through spot checks, calibrations, and data management.

Additional Information

  • Use the SmarTROLL MP System anywhere:  Reduce field equipment requirements for routine monitoring and low-flow sampling events.
  • Instantly collaborate with colleagues:  Use a wired or wireless connection to send real-time snapshots of data.
  • Streamline data management:  Consolidate all site information on your smartphone and tag data with site photos and GPS coordinates.  Log data to your smartphone and download results in a standard file format
  • Eliminate errors:  Smart sensors automatically recognize calibration solutions, store calibration data in the sensors, and perform diagnostics.  Start monitoring immediately.  Sensors are pre-calibrated at the factory with NIST®-traceable standards (where applicable).
  • Reduce maintenance:  Robust sensors stand up to field use and calibrations can last for months.
  • Get accurate results: Internal logic automatically compensates measurements for barometric pressure and salinity.
  • Ambient water quality spot checking
  • Low-flow groundwater sampling
  • Mine water monitoring
