The LISST-Logger is a fully submersible RS-232 datalogger rated to 2,000 m depth.
It is designed to work with Sequoia’s LISST-Tau and LISST-OST instruments. It logs RS-232 output from up to two connected LISST-Tau’s or LISST-OST’s. The LISST-Logger will also work with other RS-232 output sensors that send signals at once when powered up.
No software is needed for the LISST-Logger. Simply connect to the sensor and program it via its terminal window.

No. You must provide an external power source, for example a submersible battery pack, that can power both the LISST-Logger and the connected sensors. Sequoia can provide these, ask us.
The LISST-Logger has a small coin cell to keep the date and time on its internal processor, but the coin cell cannot power anything else.
The LISST-Tau and the LISST-OST require an external datalogger. All other LISST and Hyper instruments from Sequoia have their own internal datalogger and do not require an external datalogger.
Note that the discontinued LISST-ABS and LISST-AOBS from Sequoia also require an external datalogger – if you need a submersible datalogger for your LISST-ABS or LISST-AOBS the LISST-Logger will work with both of these instruments too.
