Description

U20L-004 adalah logger data tingkat rendah dengan tingkat biaya penelitian rendah untuk mengukur tingkat air dan suhu secara terus-menerus di berbagai lingkungan bawah laut. Ini memiliki akurasi pengukuran 0,1%, perumahan polypropylene untuk digunakan dalam air tawar dan garam, dan desain non-vented untuk pemasangan yang mudah dan tanpa kerumitan.


Feature

•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 13 feet
•Durable ceramic pressure sensor withstands freezing
