In-Situ BaroTROLL

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.

Applications:

• Barometric pressure monitoring
• Temperature monitoring
• Atmospheric research

• Barometric pressure, temperature & data logging in a 18.3mm (0.72 in) OD -- fits in a 25mm (1 in) well !
• Ultra-rugged, all-titanium design -- Perfect for corrosive sites
• TIG-welded seals -- Prevents flooding of instrument.
• Ultra-low power system guarantees 5 years or 2-million readings -- Forget changing batteries or running out of power.
• Uses external battery or line power -- no worries about running out of power.
• Sealed Twist-Lock hanger -- 100% reliability
• Easiest ever Win-Situ^® software -- get the data you need fast! Large, sizable display that's easy to see from a distance.
• Super accurate sensors -- record minuet changes in barometric pressure and temperature.
• Data saved by sites not files -- collect and save information by site automatically. No need to transfer data later.
• Easy-to-read memory and battery gauges -- know exactly how much is left
• Modbus, SDI-12, and 4-20mA -- provides for easy connections to existing and online systems
• Specify start and stop times for logging -- collect the data you need up to the date you want and no more
• Friendly Wizards guide every step -- reduces complicated steps and the need for tedious manuals
• -20 to 80C temperature range -- useful for research and applications with higher temperatures
• 100,000 data points of memory (1 MB) -- reduces the interval between data collection
• CE and FCC approved -- prevents susceptibility to outside emission interference and transient electrical surges
• Ability to "undelete" files from the unit -- no worries of accidentally deleting your data.
• And more!
