BaroTROLL®

The BaroTROLL® is a low-cost, self-contained logger that measures barometric pressure. It contains highly precise barometric and temperature sensors, a data logger, and internal power in a 18.3mm (0.72 in) diameter housing. Our low-owered system practically eliminates the need to change batteries and 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® instruments to compensate for changes in water level due to barometric fluctuations. Readings from the BaroTROLL® can be automatically subtracted from data collected by a 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! Built entirely from rugged titanium and welded to eliminate o-ring seals, you can have total confidence in harsh environments.

Applications: Barometric pressure monitoring Temperature monitoring Atmospheric research

Features and Benefits:

• Barometric pressure, temperature and 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 about changing batteries or running out of power.
• Uses external battery or line power – never run out of power.
• Sealed Twist-Lock hanger – 100% reliability.
• Easy-to-use Win-Situ® software – Get the data you need fast! Large, sizable display that's easy to see from a distance.
• Extremely accurate sensors – record minute 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 power 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.
• User-friendly Wizards guide every step – reduces complicated steps and the need for tedious manuals.
• -20 to 80C temperature range – use 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 – retrieves accidentally deleted data.
