Sistem InspeksiWater Level (30 ft) Data Logger - U20L-01
Water Level (30 ft) Data Logger - U20L-01 adalah logger data tingkat rendah tingkat penelitian untuk mengukur kadar air dan suhu di berbagai lingkungan bawah laut. Ini memiliki akurasi pengukuran 0,1%, perumahan polypropylene untuk digunakan di air tawar dan garam, dan desain non-vented untuk pemasangan yang mudah dan tanpa kerumitan.
Feature
Highlighted Features
- Self-contained non-vented design enables easy deployment
- Ideal for use in both fresh and saltwater environments, including wells, streams, lakes, wetlands, and tidal areas
- Depths up to 30 feet
- Durable ceramic pressure sensor withstands freezing
- HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure (see demo), temperature, and water density
