The LL-CTD-ABS-100 is a 100m water level, temperature, conductivity and salinity logger designed for long-term deployment in diverse aquatic environments, including harsh and saline conditions, thanks to its durable all-Titanium body and comes backed by a 5-year warranty. It precisely measures water levels up to 100m with a 50cm accuracy. The logger will also take conductivity (range 0-200,000 µS/cm), and salinity readings (range 0-70 PSU) with temperature (compensated across -20 to 80°C.
The LL-CTD-ABS-100 includes an integrated data logger, capable of storing 500,000 data points and powered by a 10-year lithium battery. The whole unit is housed within a 22 x 260mm all-Titanium body, ensuring resilience in demanding environments. Communication interfaces include SDI-12 and RS485 Modbus for retrieving data. The device is supported by LeveLink PC software for data processing and carries a 5-year warranty.
