The FMES (Fluid Mass Electrolytic Seismometer ) is a very respectable and extremely simple horizontal instrument with no mechanical moving parts. It is background limited even in very quiet locations such as rural Panama where it is currently operating side by side with a Trillium 40. A Force Balance Vertical is in the works based on a very simple design. Electronics are being tested in the CM-3. Expect operational tests within the month. More on this activity later. I will be bringing a second 8 channel system on line soon. It will include a 3 axis 1 Hz geophone and various broadband sensors ,experimental and professional, possibly including a Trillium 40. Exact configuration of both systems when second A/D is brought on line is still undecided.
