Portable Multi Gas Monitor
ModelGX-6000

Certifications and Approvals: ATEX, IECEx, Japan Ex, CE marking

VOCHCCH4O2H2SSO2CO● Detection of up to six gases
This monitor detects up to six gases of flammable gas, oxygen, hydrogen sulfide, carbon
monoxide, other toxic gas, volatile organic solvent gas (VOC), etc. at a time.

● Voluntary management of hazardous chemicals
Perfect for safety management of chemicals whose risk assessment is mandatory.
Multiple types of gas can be measured with one unit, resulting in improved work efficiency.

● Panic alarm & Man-down alarm*
Two new functions to protect workers’ safety.
◆ Panic alarm: Alarm is sounded manually to let people know abnormality.
◆ Man-down alarm*: Automatic alarm sound to let people around the worker know theabnormality in case of no sensed operation for a certain period.
*Normally the man-down alarm function is set to OFF. To use this function, please contact RIKEN KEIKI.

Panic alarm function

Man-down alarm function

The screen is inverted.

Panic alarm is a function inw hich t he h o lder ma nu a ll ysounds alarm to seek help ofpeople nearby or let them known
abnormality in case of trouble.

GX-6000 has a motion sensor
to sense the movement of theholder. Man-down alarm is afunction to let people around theholder know the abnormality byautomatically sounding alarmwith no sensed operation for acertain period.

Automatic 180-degree rotationof the display along with theholder’smovement.
The screen
can befixed byswitching
ON/OFF.

Detect Benzene selectively in low concentration

New 10.0eV PID sensor & Pre-filter
tube make it possible to detectbenzene selectively!
Benzene increases the risk of cancer and other illnesses.
The average allowable amount in workroom air during an
8-hour workday, 40-hour workweek(TLV-TWA) is 0.5 ppm.
GX-6000 Benzene Select Mode can measure benzene
from 0.01ppm.
