RKI GX-6100 4-Gas Monitor – LEL, O2, H2S & CO – 72-61AXXX-C

RKI GX-6100 4-Gas Monitor – LEL, O2, H2S & CO – 72-61AXXX-C

The RKI GX-6100 72-61AXXX-C is a portable sample-draw multi-gas detector configured for simultaneous monitoring of the four standard confined-space gases: combustible gas (LEL), oxygen (O2), hydrogen sulfide (H2S), and carbon monoxide (CO). This configuration includes a rechargeable Li-Ion battery pack and 115 VAC charger for convenient daily operation and recharging.

Designed as RKI's next-generation multi-gas platform, the GX-6100 combines an internal sample pump, rugged IP-67 construction, long Li-Ion battery runtime, multiple alarm functions, datalogging, and Bluetooth and IrDA communication in a compact field instrument. It is well suited for confined space entry, industrial safety, environmental monitoring, remediation work, leak detection, and other applications requiring pumped 4-gas monitoring.

4-Gas Detection – LEL, O2, H2S & CO

This GX-6100 configuration is equipped to simultaneously monitor combustible gases, oxygen, hydrogen sulfide, and carbon monoxide. These four measurements provide the core gas monitoring capability commonly required for confined space and industrial atmospheric testing.

• Combustible Gas (LEL): 0–100% LEL
• Oxygen (O2): 0–40.0% volume
• Hydrogen Sulfide (H2S): 0–200 ppm
• Carbon Monoxide (CO): 0–2,000 ppm

Internal Sample Draw Pump

The GX-6100 features an integrated sample draw pump for remote atmospheric sampling. The pump operates at approximately 0.45 LPM and supports sample distances up to 100 ft. when used with the appropriate sampling equipment.

This pumped design allows technicians to test the atmosphere of confined spaces, tanks, manholes, remediation areas, and other locations before entering or approaching the monitoring area.

Rechargeable Li-Ion Battery & 115 VAC Charger

Part number 72-61AXXX-C includes the rechargeable Li-Ion battery pack and 115 VAC charger. The GX-6100 provides up to approximately 28 hours of continuous operation using the Li-Ion battery pack, with a complete recharge taking approximately 6 hours.

• Rechargeable Li-Ion battery pack
• 115 VAC charger included
• Up to approximately 28 hours of continuous Li-Ion operation
• Approximately 6-hour complete recharge time

Rugged IP-67 Field Design

The GX-6100 is designed for demanding industrial and environmental field conditions. Its enclosure carries an IP-67 dust and water resistance rating, excluding the sample hose and probe, and the instrument includes a removable impact-resistant rubber boot for additional field protection.

Despite its extensive monitoring capabilities, the GX-6100 remains compact and portable, measuring approximately 2.6 in. wide x 7.9 in. high x 2.2 in. deep and weighing approximately 17.6 oz. (500 g) with the Li-Ion battery pack installed.
