pH/ORP and EC/TDS/Resistivity/Salinity and Temperature

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
