TROLL^® 9500 Versions
LTS
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 groundwater 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, DO, conductivity/salinity, temperature, depth. Memory is not included, but data can be logged to a RuggedReader^® handheld PC or a PC.

Profiler XP
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 of the ‘Profiler’ PLUS internal data logging for recording trends over time.

Professional XP
The most capable TROLL 9500, offering 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
