Sample Draw With PID & Super Toxics

GX-2012 gas monitor

Simply put, the GX-6000 is a game changer. This powerful hand-held instrument is capable of simultaneously monitoring up to 6 gases. In addition to the standard 4 confined space gases which include combustibles, O2, CO, & H2S, the GX-6000 has 2 additional smart channels that accept PID, IR or 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. Choosing from the library is easy with a personalized favorites list of 30 commonly used VOC’s as well as a list of 8 of the most recently used VOC’s.

The GX-6000 has a rugged design built for the nastiest environments. It is equipped with a removable impact-resistant rubber boot and a dust and water resistant enclosure with an IP-67 rating. With 5 bright LED lights on 3 sides of the instrument, alarms are easily seen from a variety of perspectives. With vibration and loud audible alarm, GX-6000 will easily alert users when needed.

GX-6000 Fireman





One of the many unique features that separates the GX-6000 from it’s competitive models is the PID sensor. With a PID sensor installed, the GX-6000 has a library of over 600 VOC compounds. The closest competitive unit has a library of only 190 VOC’s. No need to go through any complex procedures to add compounds to the GX-6000. With just a few button presses you can change to any one of the other 600 VOC’s and then be ready to monitor. No other configuration or calibrations are needed. Just choose and go.

PID listWith over 600 VOC’s to choose from, we’ve also added some tools to make it easier to find the VOC’s you’re looking for. Instead of scrolling through the entire list of 600, use the Recent menu which will store the previous 7 VOC’s used on the instrument. Or, use the User List menu, which stores 30 VOC’s of your choosing. Quick, convenient, and simple.

Also available for download is a spreadsheet containing the library of 600 VOC gases programmed into the GX-6000. This list shows each VOC available as well as the response factor assuming a standard isobutylene calibration. These response factors are also programmed into the GX-6000, so there is no need to recalibrate the GX-6000 each time the user changes VOC target gases. Just select the VOC and the instrument will display the appropriate response for the chosen VOC that is being measured.
