Model 7000 Data Logger

Model 7000 Series
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.

The following chart helps illustrate the "Electronics" and "Environmental Sensors" which are available for each instrument. The specifications are the same for the various instruments listed.
