Aquaread LeveLine Mini CTD Water Level adalah sensor pengukur ketinggian air, suhu, konduktivitas, dan salinitas titanium yang telah dirancang khusus untuk membawa pengukuran konduktivitas dan salinitas ke penerapan telemetrik Anda.
LeveLine-Mini-CTD tersedia dalam versi absolut dan pengukur. Jika perangkat datalogger / telemetri pilihan Anda menyertakan sensor tekanan udara bawaan, kami merekomendasikan versi absolut karena perangkat pencatat dapat memanfaatkan pembacaan tekanan udara untuk kompensasi. Jika sensor tekanan udara tidak tersedia maka versi pengukur paling cocok untuk pencatatan telemetrik.
Sensor pengukur memerlukan kabel berventilasi dan kartrid pengering untuk menghilangkan kelembapan dari ventilasi untuk mencegah pemblokiran dan kompensasi yang tidak akurat.
