Exceptional low noise at low frequency of our SADC20 a/d converter specifically designed to achieve the best performances with electrodynamic sensors like geophones; the ideal sensor is the HS-1 2Hz that can be embedded in the instrument as the HS1PACK or the SS-20 as external unit; cheaper solution is to use 4.5Hz embedded geophones as the GS11DPACK or outside the digitizer as the SS-45 seismic unit.
Although the SR04 is optimized for electrodynamic sensors (velocimeters) you can us it also with thirdy parties sensors as Gur__p, Kine__cs, Nano__cs or Lenn__z.

SL05C3 3 channels 24 bit SRAM recorder
Very low power consumption (1 W) with 4 Mbytes of static RAM, especially suitable for remote unaccessible installations. Limited recording capability but exceptional reliability, unbreakable.
brochure
With the same high signal quality of the SR04 the SL06 gives to the user the connectivity power of the Linux operating system with TCP/IP, HTTP, TELNET, FTP.
Memory on USB flash drives is in practical only limited by the USB memory size available on the market.
Recomended sensors are the HS1-2Hz as internal sensor (HS1PACK) or as triaxial external unit as the SS-20; a cheaper alternative is the use of 4.5Hz internal geophones as the GS11DPACK or the external triaxial unit SS-45. Although the SL06C3 is optimized for electrodynamic sensors (velocimeters) you can us it also with thirdy parties sensors as Gur__p, Kine__s, Nano__cs or Lenn__z.
SL06C3 seismic unit is has power consumption of less than 3Watts allowing its use in remote istallations with a small external battery.
brochure
SL07C3 3 channels 24 bit recorder
With the same high signal quality of the SR04 the SL07 is capable to record on SD/MMCX flash memory cards with the GSE 2.0 format and using the CM6 compression. This give a capabilty of record over 3 months in continous recording at 50 SPS.
Recomended sensors are the HS1-2Hz as internal sensor (HS1PACK) or as triaxial external unit as the SS-20; a cheaper alternative is the use of 4.5Hz internal geophones as the GS11DPACK or the external triaxial unit SS-45. Although the SL06C3 is optimized for electrodynamic sensors (velocimeters) you can us it also with thirdy parties sensors as Gur__p, Kine__s, Nano__cs or Lenn__z.
SL07 seismic unit is also capable of very low power consumption of only 1.5W allowing its use in remote istallations with a small external battery.
