In-Situ - Level BaroTROLL Precision Pressure Barometer
Accuracy: ±0.05% FS TEB from -5 to 50° C (23 to 122° F). Highly Recommended. Includes mA, ModBus and SDI-12 Outputs. Eliminates the need for an STE (Sensor Termination Enclosure) for maintenance-free operation.

Level BaroTROLL - Precision Pressure Barometer - OVERVIEW
by In-Situ
Features:
- Titanium construction
- Outputs: 4-20 mA, SDI-12, or ModBus
- Sub-1 inch diameter for easy fit
- NIST calibration report
- Accuracy: +/-0.05% FS from -5 to 50° C (23 to 122° F)
- Can be used effectively over a 3.5 square mile area and an altitude delta of 350 feet with negligible effect on correction factor accuracy (subtracting the barometric reading from an absolute submersible pressure sensor).
- In-Situ Models: Level TROLL and Aqua TROLL (non-vented, absolute pressure referenced sensors) water level loggers
- Druck Models: 1800 Series Submersible Pressure/Level Sensors (absolute pressure referenced sensors)
- Druck Models: UNIK5000 Submersibles (503X, 504X) (absolute pressure referenced sensors)
