Gas density controllers
These operate mechanically. The density of the sample gas is compared via a bellows system with the gas density in a reference gas chamber. If the density of the sample gas alters, the bellows system actuates one or more micro switches. Gas density controllers function independent of any power supply.
Trafag gas density controllers are employed internationally in gas-insulated, high-voltage switchgear in power distribution networks. Their performance record is worldwide is unique. Even at climate-related temperature fluctuations of over 135°C, they provide precise measurement results and function reliably and maintenance-free. They are therefore to be found all around the world, in the ice-cold polar regions or under the blazing desert sun.
Gas density sensors
function electronically. The consistent resonant frequency of a quartz oscillator under vacuum is compared with the resonant frequency of an identical quartz situated in the sample gas. The difference in the resonant frequency is proportional to the density of the sample gas. This difference is processed into a digital or analogue output signal.

G460 Multi-Gas Detector – Hands Free Assurance
The durable G460 continuously measures and displays readings for up to seven gases at the same time. Its functional, watertight design (IP67) and the rubberized shock resistant housing (280 grams) make the G460 an ideal device for daily operations in rough environments. A large, easy to read, three-color display changes color to indicate the severity of the alarm; the backlight color changes from green for "OK" to orange or red for an alarm. The loud audible alarm (103 dB at 12"), built-in vibrator and bright 360° LED alarm indicators alert users to hazardous conditions. The innovative backlit display can be "flipped" 180° or "zoomed" at the push of a button.
A single on/off button is all it takes for normal day to day operation. A simple three button interface provides access to advanced setup options. Calibration adjustment is completely automatic; just attach the calibration adapter and apply gas. The instrument automatically makes adjustments and retains the three most recent calibration dates for each sensor. The motorized pump includes a built-in slideshutter switch that permits operation in either diffusion or sample-draw mode while the pump is attached. The easily attachable pump is powered by its own battery pack that provides 20 hours of continuous sampling from up to 100 feet away.

Feature Highlights
* Identifies unknown gases and vapors in minutes
* No user calibration required
* Large library of gases and vapor spectra
* ReachBack 24/7/365 Technical Support
When a Response team is called upon to deal with a potentially dangerous or toxic gas, the first and most crucial question is: "What are we dealing with?" The GasID answers this question in minutes.
The GasID is a highly specific tool that measures how gases and vapors interact with infrared light. Each chemical has its own unique infrared fingerprint, which when analyzed by the GasID results in an identification.
The GasID’s compact sample collection device is carried down range into the Hot Zone and allowed to run for 10 minutes. Once the gas or vapor is collected, the sample cell is detached from the pump, passed through the decon line, and then connected to the GasID system for analysis. Users are then walked step-by-step through a touch-screen analysis process.
Once the GasID analyzes the unknown, it instantly compares the results against database libraries to provide an identity.
