Overview

Designed and tuned to meet stringent USGS OSW specifications of ±0.01 Ft. H2O often required by governmental regulatory agencies and research institutions.  The KPSI 501 incorporates a highly stable media-isolated sensor, and features SDI-12 and RS-485 serial-digital interface standards. SDI-12 is a commonly used standard for interfacing data recorders with microprocessor-based sensors, in the environmental monitoring field. The KPSI 501 is an excellent solution for applications that require minimal current drain. It will accommodate cable lengths between sensors and recorder up to 1000 feet.
