Model 8025 Micro-800 Datalogger | Discontinued

  • The Model 8025 Micro-800 Datalogger (this product has been discontinued).

The Micro-800 Datalogger is designed around the Campbell Scientific, Inc. Model CR800 Datalogger and uses the Model AVW200 Interface to read Vibrating Wire sensors. It’s housed in a sturdy fiberglass enclosure, has low power consumption, a wide operating temperature range, and has protection against lightning damage, making it suitable for use in harsh environments. The standard unit incorporates a Model 8032 Multiplexer, which allows for reading either 16 vibrating wire gauges and 16 thermistors, or 32 vibrating wire gauges. Communication is established via an optically isolated RS-232 interface, RS-485 Multidrops, Land line/Cellular modems, or radios. Power is provided by a 12 V, 7 Ah Gel Cell, maintained by either an AC charger or solar panel.

The Model 8021 has been replaced by the Model 8600 Series Dataloggers.
