The 1000 series logger is a single channel logger and is available with either a Temperature (TR) or a Depth (DR) or a Dissolved Oxygen (DO) sensor. The TGR-1050 is a modified version of the DR to support tide measurements.
The 2000 series logger is a two channel logger and is available with either of the following sensor configurations:
Temperature and Depth – TDR
Temperature and Dissolved Oxygen – TDO
Temperature and Depth – TGR for tide measurements
Temperature and Depth – TWR for tide and wave measurements
The XR series is a multi-channel logger for two to six channels. Typically it is set up to be a CTD (Conductivity, Temperature and Depth) logger but additional sensors like Turbidity, Dissolved Oxygen, Fluorescence and other can be incorporated. This Series can support up to 11 channels if required. The XR-620 is the same as the XR-420 except that it has profiling capabilities and can sample data at 6Hz rather than 1 Hz for the XR-420.
The XRX series is a CTD logger that can accommodate and additional 7 channels. It is unique in that it is expandable so that if at some time in the future you can add additional channels to it easily.
