8600 Series Dataloggers

Order Catalog


The Model 8600 Series Dataloggers are designed around the Campbell Scientific, Inc. (CSI) Model CR6 Measurement and Control System. Although primarily manufactured for use with vibrating wire sensors and thermistors, the Model 8600 Series can be configured, at Geokon’s factory, to read MEMS sensors, Carlson type sensors, voltage type sensors, 4-20 ma sensors, and numerous other specialty sensor types. The Model 8600-1 and 8600-2 Dataloggers are housed in a NEMA 4X fiberglass reinforced polyester enclosure, designed for use in harsh environments with wide temperature tolerance, resistance to moisture and humidity and protection against lightning damage. The Model 8600-3 Datalogger is housed in a rugged, water-resistant PVC enclosure (stainless steel and fully waterproof enclosures are also available) together with a battery pack (for unattended operation) and an integral Spread Spectrum Radio (for wireless data transmission).
