New Long-life Water Quality Sensor

The new Aqua TROLLâ„¢ 200 from In-Situ Inc is a multi-parameter water quality sensor designed for long periods of unattended monitoring. According to the new UK distributors, Camlab of Cambridge, the Aqua TROLL 200 is ideal for use in harsh environments for applications
such as borehole monitoring or detecting salt water contamination in aquifers and waste water systems.
Camlab’s Head of Business for Water and Environmental, David Miller, said “This is a superbly engineered, incredibly compact package that offers multi-parameter watermonitoring for about one third of the cost of a conventional system”.
The Aqua TROLL 200 accurately measures pressure, temperature and conductivity and derived parameters (Level, Total Dissolved Solids, Salinity) and can output results to a variety of data retrieval options – telemetry, laptop or PDA. Active components and the Lithium battery pack are permanently welded inside a slim (18.7mm diameter)
corrosion resistant, titanium sensor body that will pass freely down a 25mm bore pipe. The Lithiumbattery has a guaranteed life of 5 years or 200,000 sensor readings after which, for a nominal charge, the sensor head can be refurbished and re-sealed with a new battery.
