The vacuum gauge offered for use in conjunction with the
SPI Plasma Prep™ II Plasma Etcher
and the
SPI Plasma Cleaner. It is
economically priced, is very robust and can be expected to perform for many
years, yet can be depended upon to provide accurate readings of vacuum. An
ability to back fill to the same vacuum, in order to duplicate etching
rates, requires the vacuum gauge. Without this level of control over the
set up of the etching experiment, one could find some variation in the etch
rate, sample to sample.
Available in both 110/115 volt, 60 Hz and 220/230 v, 50 Hz configurations.
