XR450 vs XR5-SE

All Pace Sensors are compatible with the XR450 and XR5-SE except the Wind Speed Sensor currently works only with the XR5-SE.  Note: XR450 compatibility with the Wind Speed Sensor is in development.

The XR450 Data Logger accepts Pace plug-in modules for Relative Humidity, RH & Light, additional DC voltage ranges, and DC millivolt ranges.

The XR5-SE Data Logger does not accept plug-in modules, but Scaling Cables are available to read higher voltage ranges, and millivolt ranges can be ordered as an option.
