Measure and record water pressure, conductivity and temperature with the Aqua Troll 200, or conductivity and temperature with the Aqua Troll 100. A unique conductivity cell allows for a wide, accurate measurement range in a narrow diameter instrument.
The new multi sensor, Aqua Troll 400, is a compact instrument that houses six water quality sensors and measures 12 parameters:
- Actual conductivity
- Specific conductivity
- Total dissolved solids
- Dissolved oxygen
- Water level
- Water pressure (absolute)
Is there something I can help you with?
