Description
Accurately captures changes in atmospheric pressure to barometrically compensate absolute loggers for level measurement.
Benefits:
- Accurately measures and records barometric pressure and temperature
- Low power so battery lasts 4 years+
- Great flexibility with Modbus® RTU (RS485) protocols
- No desiccant tubes, bellows or vent tubes required
- More exact with ± 0.05% FS accuracy
- Small 2.22cm (0.875”) diameter
- Stores 50,000 records
- Ability to connect wirelessly.
