•
HI 4014 requires the Hanna HI 5315 Double Junction
reference electrode with HI 7076 as external electro-
lyte.
•
Hanna HI 4222 pH/ISE/mV meter or other suitable
ion or pH/mV meter. (Note: log/linear graph paper is
useful if an ISE (ion) meter is not available).
•
Hanna HI 180 magnetic stirrer or equivalent with
magnetic stirring bars (Note: Isolate beakers from stir-
rer motor heat by placing insulating material such as
foam or cork between them).
•
Hanna HI 76404 electrode holder or equivalent.
•
Plastic beakers ( HI 740036P) or other suitable mea-
surement vessel.

Using volumetric pipettes and glassware make dilutions to
bracket the concentration of the samples. Standards with
concentrations <10
-3 M should be prepared daily.
Store standards in plastic bottles. Add 2 mL of Hanna ISA
HI 4014-00 to 100 mL sample or standard.
