RKI GX-6100 Six-Gas Detector with PID

Name: RKI GX-6100 Six-Gas Detector with PID – Datasheet & Quote
Brand: RKI
SKU: GX-6100

A six-gas sample-draw monitor with PID, infrared and toxic options

The RKI GX-6100 is a hand-held sample-draw instrument that monitors up to six gases at once. Besides the four standard confined-space channels (combustibles, oxygen, CO and H2S) it has two interchangeable smart-sensor slots that accept PID, PPM, infrared or super-toxic sensors, so a single unit can be configured as a PID-only VOC detector or as a multi-gas tool. RKI says it can measure combustibles in the ppm range and in % volume in the same monitor.

An internal pump (0.45 L/min, 100 ft sample range), man-down and panic alarms, an LED flashlight and an IP-67 rubber-booted case make it a field tool for confined-space entry, leak detection, hazmat response and wing-tank entry. A benzene-specific version uses a pre-filter tube.

Configuring the GX-6100

Order by the sensors needed in slots 5 and 6. Any two PID sensors can be installed, and PID sensors are described as resistant to humidity. The PID unit keeps a favourites list of 30 VOCs and the last 8 used. The MOS methane and isobutane sensors must be recalibrated after H2S exposure, so avoid them where H2S is likely. Standard accessories include a rubber boot, hand strap, belt clip, probe with filter and 3 ft Teflon-lined hose; an SDM-6100 calibration station, flexible probes and sample hoses up to 100 ft are options.

Confirm before ordering: target gases and ranges, PID lamp energy, benzene-specific need, battery type, approval marking required, and a calibration plan with the correct gas.

Documents and quotation

The attached RKI datasheet lists features, sensors and specifications. Send the gases, ranges and approval requirement for a quotation. See more fire and gas detectors.

RKI gas detection range

The range covers portable monitors such as the GX-3R Pro, GX-Force and GX-6100, fixed-system detectors and controllers, wireless gas detection and calibration equipment. Typical uses are confined-space entry, refinery and petrochemical work, water and wastewater, and leak detection, with intrinsically safe approvals on the portable models.

Ordering RKI monitors

Tell us the gases and ranges, whether diffusion or sample-draw is needed, battery type and the approval marking required on site. We check the sensor configuration and calibration gas against the manufacturer datasheet before quoting. Pump-sampling units suit pre-entry checks of tanks and manholes, while compact diffusion monitors suit personal protection.
