| *Ultimate pressure is measured with Macleod gauge. In ( ) shows the measurements with Pirani gauge. |
| GLD Series, compared
with G Series, is markedly upgraded. For the sake of having
the maximum performance, in addition to notes for G series,
be careful of also the followings. |
| 1. |
GLD series is capable
of reaching to a high vacuum area (10-2 Pa).
Flanges, vessels usable at a high vacuum are required. |
| 2. |
An oil-sealed rotary
pump is not recommended for continuous operation near atmospheric
pressure. |
