Make a pH Probe Storage Solution

How do I make a pH probe storage solution to replace any spilled from the probe's storage bottle?

This solution is appropriate for any of PASCO's sensors with pH probes, including the pH (PS-2102), Water Quality (PS-2169), Chemistry (PS-2170), Advanced Chemistry (PS-2172) sensors Advanced Water Quality Sensor (PS-2230), and the PS-3204 Wireless pH Sensor.

A pre-mixed bottle of pH electrode storage solution is now also available for purchase from PASCO at
