Magseis Fairfield ZLand 3C Node - 3-Channel All in One, Sensor and Datalogger

The FairfieldNodal ZLand 3C is a compact all-in-one 3-channel sensor & datalogger with onboard GPS timing, and a self contained power supply. Originally designed for use in large N industry deployments, it has been adopted by the academic community as a useful sensor for both active and short-term passive deployments.

Unlike other sensors & dataloggers at PASSCAL, use of the ZLand 3C requires a deployment plan to be filed in advance with PASSCAL for handheld unit pre-programming.  Likewise, the units must be sent back to PASSCAL for data offload.

  • Power source: Lithium ion battery with ~35 day lifespan at 500sps continuous recording
