Deskripsi

Overview

Pencatat data berbiaya rendah dan berkelas penelitian untuk pemantauan terus menerus terhadap ketinggian dan suhu air pada kedalaman hingga 13, 30, atau 100 kaki di berbagai lingkungan bawah air. Pencatat data ini memiliki akurasi pengukuran 0,1%, wadah polipropilena untuk digunakan di air tawar dan air asin, dan desain tanpa ventilasi untuk penggunaan yang nyaman dan tidak merepotkan.

Features

  • Self-contained, non-vented design enables easy deployment
  • Ideal for use in both freshwater and saltwater environments, including wells, streams, lakes, wetlands, and tidal areas
  • Depths up to 13, 30, or 100 feet depending on model
  • Durable ceramic pressure sensor withstands freezing
  • HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature, and water density
