Case
The GX-2009’s sturdy, high-impact plastic case is suitable for use in many
environmental conditions, indoors and out. The unit is dust proof and water
resistant. Rubber overmolded surfaces on much of the case help protect it
from impact damage and aid in holding the instrument in your hand.
A clear plastic window through which the LCD can be viewed is located on
the front of the case. Three brass charging contacts that are used when the
GX-2009 is placed in the charging station are on the back of the case. Four
sensor diffusion ports are located on the bottom of the case. The ports are
labelled as follows from left to right: H
2
S, CO, HC, and O2. Three frosted
windows, one on the left side, one of the right side, and one on top, cover
alarm LED arrays. There are two buzzer sound openings, one on the front
below the LCD and one on the top behind the top LED array. An IR
(infrared) communication port is located on the top left side which is used
to transfer information when the instrument is used with one of the
calibration or downloading accessories.
There are three threaded inserts on the back of the case. These are used
to mount the alligator clip or the optional belt clip.
