RKI GX-Force 4 Gas Monitor with Case 72-FA-A-A10-50
Description
The RKI GX-Force 4 Gas Monitor is a versatile multi-sensor detection system designed to protect workers in hazardous environments. This rugged unit monitors combustible gases (LEL), oxygen, hydrogen sulfide, and carbon monoxide simultaneously—making it ideal for confined space entry, refineries, utilities, oil and gas operations, and emergency response. Powered by a rechargeable Li-Ion battery and housed in a protective padded case, the GX-Force delivers rapid response times and customizable alarm thresholds to meet OSHA and industry standards. Perfect for personal monitoring and team safety in high-risk industries.
Applications:
Personal monitoring, Confined spaces, Refineries/petrochemical, Utilities, Oil and Gas, Water/wastewater, Fire services, Construction
Kit Includes:
-
RKI GX-Force 4 sensors, LEL / O2 / H2S / CO gas monitor with Li-Ion battery pack
- 100-240 VAC charger
- Belt clip
- USB A to USB C data downloading cable
- Rubber nozzle
- 10’ hose with probe
- Padded Case
Remember to calibrate every six months and regularly perform bump tests.
Note: calibration gas is not returnable. Please check your selection carefully before ordering.
