Model 8021 Micro-1000 Datalogger | Discontinued

  • The Model 8021 Micro-1000 Datalogger (this product has been discontinued).

The Micro-1000 is a complete datalogger, designed around the Campbell Scientific, Inc. (CSI) Model CR1000 Measurement and Control System. This interface is designed to eliminate the effects of electrical noise and interference on vibrating wire sensor signals. Although manufactured primarily for use with vibrating wire sensors and thermistors, virtually any type of sensor can be read by the Micro-1000 datalogger. The Micro-1000 can be configured to read Carlson type sensors, voltage type sensors, 4-20 mA sensors, and numerous other specialty sensor types. When used with GEOKON Model 8032 Multiplexers, the standard Micro-1000 datalogger can read up to 96 vibrating wire sensors and 96 thermistors. Optionally, the system can read up to 256 two-wire sensors.

The Model 8021 has been replaced by the Model 8600 Series Dataloggers.
