Target Acid Sensor
The second sensor completes the electrochemical sensor array to detect inorganic
acids and/or bases. The target sensor contains an electrolyte and is similar to an
electrode used to measure pH or ions in water. When a target chemical such as an
inorganic acid migrates into the electrolyte, the potential of the electrode is
modified signaling an alarm condition.
