Alligator and Belt Clips

The GP-01 is available with two types of clips, the alligator clip and the belt

clip. Both are illustrated in Figure 2 below.

The alligator clip can be used to attach the GP-01 to clothing or a belt.

Teeth in the clip’s jaws prevent the unit from slipping off. The belt clip is

used to easily clip the GP-01 on a belt.

Membrane Retainer and Filter Disks

The membrane retainer is held in place by a single Phillips screw. Two

types of paper-like ﬁlter disks may be installed beneath the membrane

retainer. The smaller of the two, the H2S scrubber ﬁlter disk, removes H

from the air. The larger one, the sensor cover, protects the sensor from dirt

and moisture.

The H

S scrubber ﬁlter disks are not installed in the GP-01 as shipped from

the factory. They can be installed to protect the combustible gas sensor

from H

S exposure if H

S will be present in the monitoring area.Two H

scrubber ﬁlter disks ﬁt into a recessed area in the sensor retainer directly

above the sensor. If installed, they prevent H

S that is present

in the monitored air prolongs the life of the sensor. These ﬁlters are white

when new and darken as they absorb H

S. They must be changed when
