In-situ Marine Optics - Model DL3 -Long-term Submersible Data Logger
The DL3 Long-term Submersible Data Logger is designed for extended deployment in marine environments, providing accurate and reliable data collection. Its submersible nature allows for continuous monitoring of underwater parameters such as conductivity, temperature, and pressure (CTD) with a high degree of precision. The device is suitable for various applications including oceanographic research, environmental monitoring, and underwater equipment testing. Its robust construction ensures durability and operational integrity in harsh conditions, making it a valuable tool for researchers and professionals needing long-term data acquisition. The DL3 data logger's efficient power management and storage capabilities accommodate extended recording periods, and it is engineered to be compatible with associated marine optics and instrumentation.
A three-channel datalogger for RS232 devices, designed for long term underwater deployment.
