TROLL 9500 Versions:
  • LTS stands for “Level, Temperature, and one additional Sensor” such as conductivity, pH, or dissolved oxygen.
    This version also includes internal data logging. It can be used for coastal applications or to measure ground water quality over time.
  • Profiler; Ideal for water quality sampling or profiling. The Profiler allows for any of the key water parameters such as pH, ORP, D.O., conductivity/salinity, temperature, depth. Memory is not included, but data can be logged to a
    RuggedReader or a PC.
  • The Profiler XP offers the same features as the ‘Profiler’ unit, but with the option to use XP or “Extended
    Parameter” sensors, such as turbidity, ammonium, nitrate, and chloride.
  • Professional; This version offers the highest value for most applications allowing for all the key parameters similar to the ‘Profiler’ PLUS internal data logging for recording trends over time.
  • Professional XP; The most capable TROLL 9500 that
    offers the same features as the ‘Professional’ unit, but with the option to use XP or “Extended Parameter” sensors, such as turbidity, ammonium, nitrate, and chloride.

Compact Sensor Configurations
Use the TROLL® 9500 for profiling, surveying, and monitoring. It features the most sensors in a 1.85-inch (4.7-cm) housing with 5 sensor ports plus temperature and barometric pressure sensors. The compact design allows for all of the standard parameters such as DO, conductivity, pH/ORP, temperature, turbidity, level or measure, and an additional ISE parameter like nitrate, chloride, or ammonium.

 

 
Sub-2 inch TROLL 9500 with RDO® Optical DO Sensor

Use the RDO direct connect unit with all models of the TROLL 9500. For sub-2 inch configurations, turbidity and/or pressure cannot be used.

Port 1 = pH, pH/ORP, or ISE (XP units)
Port 2 = RDO sensor
Port 3 = RDO sensor
Port 4 = Conductivity (high or low)
Port 5 = Plugged

Sub-4 inch TROLL 9500 with RDO Optical DO Sensor

Use the RDO cable connect unit with all models of the TROLL 9500. Any TROLL 9500 with turbidity, pressure, or both must use a sub-4 inch configuration with adapter.

Port 1 = RDO sensor, pH, pH/ORP,
or ISE (XP units)
Port 2 = ISE (XP units)
Port 3 = RDO sensor, pH, pH/ORP,
or wiper
Port 4 = Conductivity (high or low)
Port 5 = Turbidity (XP units), pressure,
or both
