- Compact body with batteries contained and unnecessity of a storage box
- 2 types of wireless function, mobile phone network and 2.4 GHz wireless-link
- The main [M4] being linkable up to 3 subs [S4]
- Saving work cost and communication charge by reducing installation time and transmitting monitoring data by aggregating between several loggers
- Connecting analog sensor, S&DL series (digital sensor) and rain gauge (pulse output)
- Threshold judgment function with being changeable measurement and transmitting interval automatically
- Retrieving data with SD card instead of data transmitting in case of some communication failure
- Synchronizing time and acquisition of its position roughly by GPS
