Multi-Parameter TROLL 9000 Water Quality Monitor

The new TROLL 9000 is a lightweight, multi-parameter water quality monitor that uses the most current sensor and electronics technology. Capable of monitoring up to 9 parameters simultaneously, the TROLL 9000 is the ultimate tool for water quality profiling applications and unattended long-term deployments. The TROLL 9000 is constructed of 316L stainless steel, making it rugged, yet lightweight and features many new technological innovations, such as: Smart Sensors, Digital DO, Factory Pre-Calibrated Sensors and Single Quick-Calibration Solutions

The TROLL 9000 interfaces with a Compaq Pocket PC or with any laptop computer or with a SDI-12 logger for long term data logging. All memory enabled units ship standard with up to 4 MB of memory for internal logging of over one million data points.

There a 5 models available, so use the chart at the bottom of this page to determine which model will best suit your application: Profiler, Profiler XP, Professional, Professional XP, or LTS.

 Japanese information

1. ISE* (pH, ORP, ph/ORP combo, Nitrate, Chloride, Ammonium)
2. Dissolved Oxygen or ISE (pH, ORP, Nitrate, Chloride, Ammonium)
3. ISE (pH, ORP, ph/ORP combo, Nitrate, Chloride, Ammonium)
4. Conductivity or ISE (pH, ORP, ph/ORP combo, Nitrate, Chloride, Ammonium)
5. Fixed Port - Pressure, Level, Depth, Open Channel Flow, Turbidity (when available)
Temperature is standard on all units and Barometric pressure is optional.
ISE = Ion Selective Electrode (single or combo e.g. pH/ORP)

For example, here are two   configurations that are possible. Many more exist!
Example configuration #1: DO, Conductivity, Temperature, pH/ORP, Nitrate, Level
Example configuration #2: Temperature, pH/ORP, Nitrate, Chloride, Ammonium

Up to this time, stirring with field instruments has not be practical due to the excessive power requirements. Additionally, stirrers that are currently available on some multi-parameter units are simply too turbid on the sample to obtain quality measurements.

In-Situ's Stirrer solves these problems by slowly and deliberately stirring the sample. It is similar to those recommended for use in a laboratory providing minimal sample agitation without being too turbid. Plus, a single user-replaceable D-size alkaline battery provides power for over 6 months! The result? Laboratory grade measurements in the field!

4 Versions Offered -- a solution for every job

The MP TROLL 9000 is offered in six versions. The versions are scaled to meet the needs and budgets of those organizations and individuals monitoring surface water, and those monitoring ground water respectively. All versions share the same highly engineered circuitry, accuracy, patented "Quick Connect" cable system as well as lightweight, high-quality 316L stainless steel body. The versions consist of "Basic" and "Profiler" - instruments specifically designed for quick basic measurements of surface water. "Profiler XP" - designed for more extensive quick measurements of surface water. "Professional" - allowing for basic monitoring of either ground or surface water with advanced memory and data logging capabilities. "Professional XP" - designed for extensive long-term monitoring with advanced memory and data logging capabilities. "LTS" or Level, Temperature and one water quality Sensor - Allows for precision ground water measures of level, temperature and one water quality sensor and includes advanced data logging functions. Units with memory functions are enhanced with up to 4mb of non-volatile memory, allowing logging of over 1 million data points. Except for the Basic unit, all versions are upgradeable in the field should testing needs change.
