The main difference between the SITE-LOG and PRECISE-LOG series is how they communicate with a computer and the number of external input channels they provide.
SITE-LOG Series
Most SITE-LOG data loggers provide:
- 7 external input channels
- 1 built-in temperature channel
- USB communication with a computer
- Operation from the internal battery in standalone mode
- Optional external power when required
SITE-LOG data loggers are normally connected directly to a computer through USB for configuration and data download.
PRECISE-LOG Series
PRECISE-LOG data loggers provide:
- 8 external input channels
- USB communication
- WiFi communication
A PRECISE-LOG data logger can communicate with a computer either through its USB connection or over a WiFi network.
The WiFi function can be turned on or off. When WiFi is disabled, the logger can operate in standalone mode in a similar way to a SITE-LOG data logger.
