3. GENERAL DESCRIPTION & INTENDED USE
The
HI7640-58
series are optical dissolved oxygen probes with Smart Caps (
HI764113-1
) for measurement
of dissolved oxygen.
The series is designed to work with the Hanna Instruments
®
HI510
Universal Process Controller. When paired with
the controller, the system provides accurate dissolved oxygen measurements auto-compensated for barometric
pressure, salinity (set manually), and temperature.
Suitable for control applications in aeration basins, ponds, and tanks where optimizing oxygen transfer is a
key element, the probe can be submersed/immersed in a tank using the
3/4
” NPT threads, or installed in a
flow cell using the lower sensor threads.
The probe is available with an
integral connector
that permits connections with no twisted cables as cables
are connected after installation.
Patch cables
may be purchased separately to connect between the probe and controller up to 50 meters (164 ft).
