We, AST LLC(Moscow, Russia), designed and manufactured rotational seismometers for eentec up to date.
The R-1 is obsolete since 2009 and replaced by the R-2 with the better specs and the MHD calibration input.
The R-2 is currently in production, see the attached specs.
The R-3, the weak motion unit, will be available later this year.

> Dear Colleagues,
> We are looking for any commercial rotational seismometers for research. It seems the only choice is eentec R1 (http://www.eentec.com). But I have been told that this company has been down because its owner, sadly, has passed away. Would you suggest any other choice for us to buy some units of rotational seismometers?
