Nanometrics Trillium 120 Posthole Broadband Sensor

Note: EPIC has purchased 11 Nanometrics Trillium 120PH seismometers.

Automatic levelling can be remotely initiated to correct leveling of up to +/- 5 degrees (+/-10 degrees is also an option), simplifying down-hole installations
The axis stack is mechanically levelled to ensure that the vertical axis does not couple horizontal noise
A robust, waterproof, stainless steel enclosure ensures the sensor is protected from hostile environments
The down-hole design includes a 5.6 inch diameter casing, single marine grade connector and a centered attachment eye bolt on the top surface
Low power consumption of 560mw minimizes power source requirements at the site
Exceptional self noise below NLNM at 100 seconds is well suited for quiet down-hole installations
