SatLink3 Logger/Transmitter SL3-1

The World’s First Wi-Fi Multi-Communications Logging Transmitter

Sutron’s SatLink3 provides a cost-effective way to measure, log, calculate and transmit data from remote locations around the world. The unit monitors 32 independent measurements of most hydrological, meteorological, environmental or related sensors.

SL3 has built-in support for all meteorological satellites including GOES, EUMETSAT, INSAT and MTSAT for operation anywhere. Most often used directly connected to sensors and transmitting data on a user-set schedule, the Satlink3 has options for cellular and Iridium communications.

Satlink3 builds upon Sutron’s 35 years’ experience providing reliable satellite communications.

  • Expanded measurements from 16 to 32
  • Improved analog accuracy & additional analog channels
  • Two independent SDI-12 inputs expand SL3’s benefits: (a) If an SDI sensor or SDI wires are damaged or knocked offline, the other SDI sensor will continue to operate. (b) Two independent SDI ports also increase flexibility of SDI sensor scheduling.
  • Optional cell/Iridium modems for redundant 2-way communications
  • Wi-Fi for operation with wireless devices, including smart phones, tablets and PCs
  • Expanded log from 120,000 to 1,000,000 readings
  • Improved GUI program that runs on Android, iPhone, PC or MAC devices
