RKI Instruments GX-6100 Sample-Draw Gas Monitors
Every GX-6100 configuration we stock, with its price and add to cart: 333 part numbers from one to six gases. RKI's GX-6000 page says "The GX-6000 has been discontinued. Please see GX-6100 as an alternative." RKI describes the GX-6100 as a hand-held 6 gas detector with pump: the four confined-space gases plus two smart channels for PID, ppm, infrared or super-toxic sensors, with an internal sample pump, man-down and panic alarms, an LED flashlight, Bluetooth, and a choice of Li-ion (28 hours) or alkaline (8 hours) battery packs. Figures below are as published by RKI Instruments. Ships in 1–2 business days; most orders arrive in 3–7 business days.
GX-6100 configurations by sensor set
The suffix of the RKI part number is the power configuration: -A alkaline pack only, -B alkaline and Li-ion packs with a 100-240 VAC charger, -C Li-ion with a 100-240 VAC charger, -D Li-ion with a 12 VDC charger, -E alkaline and Li-ion with 12 VDC, -F Li-ion with both chargers, -G alkaline and Li-ion with both chargers, -H Li-ion with no charger.

SDM-6100 calibration station
The SDM-6100 is a versatile maintenance tool that automates the service of a GX-6100 portable gas monitor. This docking station can be used as a stand alone device for charging, calibrating and bump testing, with all records stored automatically for future upload to a PC via USB flash drive or LAN import (PC software and flash drive included). The SDM-6100 can also be connected to a PC for automated calibration, bump testing, and archiving of datalog data from GX-6100 instruments. Up to ten SDM-6100 docking stations can be connected simultaneously using USB cables. The SDM-6100 includes connections for one to three calibration gas cylinders.

RKI Instruments GX-6100 Sample-Draw Gas Monitors questions
Is the GX-6100 the replacement for the RKI GX-6000? RKI's GX-6000 page says: "The GX-6000 has been discontinued. Please see GX-6100 as an alternative." Per RKI's feature list the GX-6100 adds a TC sensor for % volume combustibles, ppm MOS methane and isobutane sensors, dual PID support and emergency alerts over Bluetooth.
What gases does the GX-6100 detect? Benzene (benzene-specific PID, 10.0 eV lamp), methane (infrared, % LEL and % vol), carbon monoxide (CO), carbon dioxide (CO2, infrared, 0-10% vol), carbon dioxide (CO2, infrared, 0-10,000 ppm), chlorine (Cl2), hydrogen sulfide (H2S), hydrocarbons (infrared, isobutane, % LEL and % vol), hydrogen cyanide (HCN), combustible gas (LEL, catalytic), ammonia (NH3), nitrogen dioxide (NO2), oxygen (O2), sulfur dioxide (SO2), VOCs (PID, 10.6 eV lamp, 0-4,000 ppm), VOCs (PID, 11.7 eV lamp, 0-1,000 ppm), VOCs (PID, 10.6 eV lamp, low range 0-40,000 ppb), methane % volume (thermal conductivity) across the configurations we stock; RKI lists LEL, O2, CO, H2S, PID VOCs, benzene, NDIR CO2, methane and hydrocarbon, TC % volume methane, and the toxics NH3, Cl2, HCN, NO2, PH3 and SO2.
Is the GX-6100 intrinsically safe? Yes. RKI lists the GX-6100 as intrinsically safe (ATEX / IECEx / cCSAus) with the explosion class Ex ia IIC T4 Ga, TIIS approval and CE marking.
Is the GX-6100 a PID monitor? It can be: RKI's two smart channels take PID sensors (10.6 eV, 11.7 eV and a low-range 10.6 eV lamp, plus a benzene-specific 10.0 eV PID), alongside the four confined-space gases, as RKI describes the GX-6100; the PID configurations are in the tables above.
How long does the GX-6100 battery last? 28 hours on Lithium-ion battery pack. Complete recharge in 6 hours. 8 hours Alkaline battery pack (3 AA size in each pack), as RKI lists it; the packs are interchangeable.
How far can the GX-6100 draw a sample? RKI lists an internal sample pump with a 0.45 LPM flow rate and a 100 foot sample range; the standard kit includes a 3 ft Teflon-lined hose and probe, and RKI lists hoses up to 100 ft as optional.
