Aqua TROLL 500 Multiparameter Sonde
The Aqua TROLL 500 uses the latest sensor and electronics technology to provide laboratory-quality measurements for field use. Parameters include water level, pH, dissolved oxygen, and more. The instrument fits inside wells as small as 2” in diameter. The water level/pressure sensor and barometric pressure sensor are integrated into the sonde. Additional sensors may be selected and replaced to suit your project’s needs. An optional motorized sensor wiper may also be included on the instrument.
