Dear All,I am about to buy an instrument capable of autonomously measuring oxygen, pH, temperature, depth and salinity in marine environments (up to 30 m depth, 3-5 day continuous deployments). Does anyone have experience using the In Situ Troll 9500 for marine deployments? I am trying to choose between this instrument and the YSI EXO2. My main concern with the Troll is that it seems to have been developed for sampling wells and I wonder if there are any issues when using this in a marine exposed environment. It is considerably cheaper than the EXO which is why I am looking into it. Best Regards,Ylva
