*Evaluator notes that because of the geometry of the vapor sensors and their varied installation options, the threshold level was not measured.
** Evaluator notes that this sensor resets very slowly and that controller should be adjusted or replaced after each alarm.

Specificity Results:
Part #30-3222 responds to hydrocarbons only.
Part #3223 works with any liquid.

Comments:
Performance of these sensors degrades after exposure to high concentrations of hydrocarbons.
