Hi, we are looking for some relatively small, robust loggers to record pH, oxygen and temperature. They would need to be suitable for marine deployments and waterproof to >10 m (>30 ft) depth. Does anyone have (positive) experience with this type of instrumentation or know of a good manufacturer that I could contact? I have heard that there are some Japanese firms that have developed small loggers, but have not been able to find them online.
Thank you!Regards, Ylva Olsen, Research Associate UWA, Australia
