I definitely get a distinct whiff of ozone when I open the cover of my eraser after its been on a few minutes. cheers Roland -----Original Message----- From: Lance Allen To: PICLIST@MITVMA.MIT.EDU Date: 13 August 1999 00:37 Subject: Re: Eprom eraser > Hi all > Is the shortwave UV lamp in an eprom eraser the type that > produces ozone? > Thanks I probably should let this go But I cant help myself.... UV producing ozone as a product? I thought ozone O3 was a charged oxygen ion that happens due to high voltages like lightening, high voltage PSU,s etc and that ozone had UV blocking properties somewhat useful to life on earth and that CFC's go around removing said charge in a catalytic manner, thus undoing our useful ozone layer. But then again this might be another trick question???????? _____________________________ Lance Allen Technical Officer Uni of Auckland Psych Dept New Zealand _____________________________
