Alat Perekam Data Level Air Tawar HOBO 13-Foot Fresh Water Level Data Logger U20-001-04

Tekanan Mutlak, Tekanan Barometrik, Suhu dan Ketinggian Air

Pantau ketinggian air dan suhu di sumur, sungai, danau, dan lahan basah (air tawar) dengan Pencatat Data Ketinggian Air HOBO setinggi 13 kaki ini. Dengan jangkauannya yang sempit, logger ini memberikan akurasi terbaik di perairan dangkal. Logger ini menawarkan nilai yang besar dan penyebaran yang mudah karena tidak ada tabung ventilasi atau pengering yang rumit untuk dirawat. Untuk penyebaran air asin, seperti lahan basah payau dan daerah pasang surut

HOBO Water level data logger U20-001-04 Memantau ketinggian air dan suhu di sumur, sungai, danau, dan lahan basah (air tawar) dengan Pencatat Data Ketinggian Air HOBO setinggi 4 meter (13 kaki) ini. Dengan jangkauannya yang sempit, logger ini memberikan akurasi terbaik di perairan dangkal.
