The Multi Parameter Troll 9000 (MP-Troll 9000) water quality probe from In-Situ Inc. features the most current sensor and electronics technology in a lightweight package. Innovations in the new probe include smart sensors, digital DO readouts and factory pre-calibrated sensors.

The compact, 1.75 inch diameter probes are offered in six versions, with options to monitor temperature, pressure, level, depth, DO, conductivity, pH, ORP, TDS, resistivity, salinity, nitrate, chloride, ammonium, ammonia, turbidity & chlorophyll.

The MP-Troll 9000 interfaces with an ultra-light, weatherized PDA for surface water profiling or with any laptop computer or SDI-12 logger for longer-term tests. All memory-enabled units ship standard with up to 4mb memory for internal logging of over 1 million data points.

The multi-parameter water quality sensor market is maturing. In-Situ has designed the MP-Troll 9000 from the inside out, using all of the most current proven technology.

This Technology Includes:
Smart Sensors — pre-calibrated directly at the factory. These sensors may be plugged into one of the option ports and put to immediate use.

Digital DO — allows the user to selectively monitor Dissolved Oxygen (DO) to a very high accuracy by either stirring or non-stirring methods. This greatly simplifies DO measurement, as well as conserves battery power for long-term monitoring. DO measurements are digitally compensated for changes in temperature, salinity and barometric pressure.

A "Single, Quick-Cal Solution" — allows the user to calibrate DO, conductivity, pH, and ORP simultaneously to a high degree of accuracy. The new innovations are enabled by using new advances in micro-electronics, as well as patented sensor designs. Up to nine sensors may be monitored concurrently. The low-power circuitry allows the MP-Troll 9000 to be deployed for months at a time, using off-the shelf alkaline D-Size batteries.

VersionsThe MP-Troll 9000 is offered in six versions. The versions are scaled to meet the needs and budgets of organizations and individuals monitoring surface water and/or ground water. All versions share the same circuitry, accuracy, patented "Quick Connect" cable system as well as a 316L stainless steel body.

The versions consist of "Basic" — specifically for those needing the power of a multi-parameter probe, but not needing to upgrade to a more advanced unit. "LTS" — providing Level, Temperature and the customer's choice of one extra sensor. "Profiler" — an instrument 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 memory capability. "Professional XP" — designed for extensive long-term monitoring with memory capability.

Units with memory functions are enhanced with up to 4mb of non-volatile memory, allowing logging of over 1 million data points.

All versions with the exception of "Basic" are upgradable in the field, should testing needs change.

Data AcquisitionData is stored in 4mb of memory on the Professional, Professional XP and LTS models, while it may be logged to the water resistant Pocket-Situ PDA on Basic, Profiler and Profiler XP models. All data is retrievable and able to be viewed, manipulated and exported with Win-Situ 2000 software, which is included with every probe.

Remote data acquisition is enabled through the In-Situ ETS Telemetry system. The system is capable of transmitting over landline, cellular, radio and GOES satellite networks, as well as integrating into customer's Internet-enabled platforms. All In-Situ probes are networkable, allowing multiple test sites to be centrally monitored. WW/
