Model 8026

The Model 8026 Wireless Datalogger is intended to transmit data from buried sensors installed in inaccessible locations. It’s designed around the Campbell Scientific, Inc. Model CR800 Datalogger, specifically to read GEOKON's line of Vibrating Wire sensors. The 8026 Datalogger is housed in a rugged enclosure (standard enclosure is PVC, optional stainless steel enclosure also available) together with a D-cell lithium battery pack (for unattended operation) and an RF modem (for wireless data transmission). It has low power consumption, wide temperature range and is moisture resistant. It’s configured to read 6 sensors; either 6 VW or 3 VW plus 3 thermistors, or any combination thereof. The 8026 is typically installed with a Spread Spectrum Radio Modem and Antenna.
