The BaroTROLL® is a low-cost, self-contained logger that is used to measure barometric pressure. It contains high precision barometric and temperature sensors, a data logger, and internal power in a 18.3mm (0.72 in) diameter housing. There is no need to change batteries with our new super low-power system that guarantees long-term operation. Alternatively, the unit can be powered with external power. System integration is a snap with built-in RS-485/232 Modbus, SDI-12, and 4-20mA communications.
The BaroTROLL® is typically used in conjunction with one or more of the non-vented Level TROLL® to compensate for changes in the water level due to barometric fluctuations. Readings from the BaroTROLL® can be automatically subtracted from data from the Level TROLL®. Due to its small size, it can be installed at the surface or inside the well casing--even in 25mm (1 in) wells! Since it is built entirely from rugged titanium that is welded to eliminate o-ring seals, you can have total confidence in tough environments.
