GX-6000 PID Gas Monitor

introduction video


PID, O2, CO, H2S, VOC and Super Toxic Sensors

Equipped with a strong internal sample pump, a man-down alarm, a panic alarm, an LED flashlight, and large auto rotating LCD display, the GX-6000 can operate as a single gas PID unit or a multifunctional tool utilizing all 6 channels.

The GX-6000 with a PID sensor will come equipped with a library of over 600 VOC gases to choose from as standard. A benzene-specific version is available using a pre-filter tube for detecting low levels of benzene. The GX-6000 has a rugged design built for the nastiest environments.



Static & drawDown Levels

The GX-2012 is like having multiple tools in one instrument. Having 3 operating modes, the GX-2012 can be used for confined space, safety monitoring in it’s Normal Operating Mode; for leak investigation in Leak Check Mode; and for underground leak checking in Bar Hole Mode. When equipped with an optional TC sensor, the GX-2012 can measure 100% volume methane and dynamically auto range from % LEL to % volume, making it ideal for line purge testing.



the next generation of EAGLE's

The EAGLE 2 features a PID sensor for detecting high or low ppm levels (0-50 & 0-2,000) of VOC gases; % volume capability for CH4 and H2 using a TC (thermal conductivity) sensor; PPM or LEL hydrocarbon detection at the push of a button; infrared sensors for CO2 (ppm or % volume), methane or hydrocarbons in LEL and % volume ranges; methane elimination feature for environmental applications; and a variety of super toxic gases.

With its ergonomic design, the EAGLE 2 offers easy access to controls such as autocalibration, alarm silence, demand zero, peak hold, methane elimination, and a wide variety of other features.


Beacon™ 110

Single Channel Wall Mount Controller

The Beacon 110 is a powerful, low cost fixed system controller for one point of gas detection.  It is microprocessor controlled, versatile, simple to install and operate, and priced to be the industry’s best value single gas detection controller.  It is capable of accepting RKI sensors directly for LEL level combustibles, Oxygen, Hydrogen Sulfide, or Carbon Monoxide.



Beacon™ 800

8 Channel Wall Mount Controller

The Beacon™ 800 is a simplified, versatile, low cost fixed system controller for one to eight points of gas monitoring.  It is microprocessor controlled and is capable of accepting up to 8 separate 4-20 mA sensor transmitters, which can be either 2 or 3 wire.  It can also be powered by either 24 VDC or 115 VAC.



M2A Series

Stand Alone Transmitter

The RKI M2A™ is a state-of-the-art transmitter that can operate as an independent, stand-alone monitor or as part of an integrated system. The M2A connects with an analog or digital signal to virtually any controller, PLC, or DCS. Setup procedures are simplified with user friendly push buttons and OLED menus. It utilizes a magnetic wand technique for performing non-intrusive calibration.


RKI Calibration Station

stand alone calibration station

The SDM-6000 is a versatile maintenance tool that automates the service of a GX-6000 portable gas monitor. This docking station can be used as a stand alone device for charging, calibration and bump testing, with all records stored automatically for future upload to a PC via SD card (PC software and SD card included).
