The HI5521 is an advanced, two channel research grade
benchtop pH/ORP and EC/TDS/Salinity/Resistivity meter that
is completely customizable with a large color LCD, capacitive
touch keys, and USB port for computer connectivity.
The HI5521 allows for simultaneous measure of pH or ORP on one
channel and EC or related parameters on the other. Channel one
has a BNC connection for use with the expansive line of pH and ORP
electrodes that Hanna Instruments o!ers. The meter is supplied with
the HI1131B glass body, double junction, combination pH electrode
that operates over a wide temperature range from 0 to 100°C. All
readings are automatically compensated for temperature variations
with the separate HI7662-T temperature probe or from the built
in temperature sensor of the conductivity probe on Channel two.
The HI5521 is supplied with the HI76312 four-ring conductivit
