Model 7000 Series Data Loggers
Water Monitoring Instruments
The Series 7000 data recording instruments are assembled from standard components to meet each customer's individual requirements.
An internal clock, re-settable by user, tags each data reading with the date and time at which it was taken.
The housing is our time-tested "hard coat anodized" aluminum cylinder with patented G.O. "spaghetti line" end cap locks. Housings are pressure rated to 5000 meters (sea water) when properly sealed.
