Aqua Troll 200 from Enviroequip

Friday, 23 March, 2007 | Supplied by:

The new Aqua TROLL 200 is the first in a new line of water quality instruments from In-Situ Inc.

It monitors and logs conductivity, level/pressure and temperature in the harshest environments. Designed to combat fouling and conserve power, the Aqua TROLL 200 is built to extend deployment. The Aqua TROLL is powered on external 8-36 VDC or internal batteries that are guaranteed for 5 years when logging in 15-minute intervals.

Ultra-rugged, corrosion-resistant, titanium construction, and a small 18.3 mm diameter make the Aqua TROLL 200 ideal for demanding marine, surface and groundwater applications. Building on the successful Level TROLL platform, the Aqua TROLL 200 is SCADA and telemetry capable. Standard outputs include Modbus/RS485, SDI-12 and 4-20 mA.

Select between gauged and absolute models with ranges up to 500 psi. All models feature a 4 MB memory that stores up to 200,000 data points. Standard logging modes include linear, fast linear, linear average and event testing with sampling rates as fast as 1/sec.

Installation and data acquisition is simplified using In-Situ RuggedCable and powerful Win-Situ software. Use the durable RuggedReader handheld PC for fast instrument set-up and downloading in the field.
