SALINTEST
HI 98203
Salinity Concentration
Pocket-sized Meter
GENERAL INFORMATION
The SALINTEST utilizes a sodium ion-selective
glass electrode to determine the activity of sodium
ions in solution.
When dissolved, NaCl ionizes to form Na
+
and Cl
-
ions. Measurement of Na
+
ion concentration is
an indicator of the concentration of NaCl.
The relationship between the SALINTEST read-
ing and the g/L NaCl scale is shown in the
logaritmic chart below.
A double junction reference is used to ensure a
highly stable reading.
If you suspect that the calibration has drifted,
you can recalibrate the meter by using HI 7081
or a solution of known concentration (adjust the
reading with the calibration trimmer).
HOW TO USE THE CHART
• Locate the pNa reading on the horizontal axis
of the chart.
Move vertically upwards to intersect with the
45º line.
• Move horizontally and read the “g/L of NaCl”
value.
E.g. Display = 0.42
g/L NaCl = 22
