Automatic PID Cleaning

MultiRAE products offer auto-cleaning, a unique feature that reduces PID lamp cleaning. When
a MultiRAE equipped with a PID lamp is charging in a desktop cradle, truck mount, or AutoRAE
2 cradle (but not a Travel Charger), the PID lamp turns on for two hours and generates a small
concentration of ozone. Ultraviolet light and ozone molecules then burn off heavy
contaminants that may have built up on the lamp and sensor. Then the pump runs for 20
minutes to exhaust gas contained inside the gas plate. After the pump stops, the battery
continues to be charged, if necessary. Note: This function also works when the instrument is
turned off
