Gas Detection
Multi-Gas Detector is Key Component of Life Safety Solution
Industrial Scientific (USA) is pleased to announce the availability of the Ventis™ LS multi-gas detector as part of the Accenture Life Safety Solution. Using Wi-Fi and location-based technologies to remotely monitor those working in potentially hazardous environments, this wireless solution helps keep people safer.
The Accenture Life Safety Solution leverages the expertise of Industrial Scientific, as well as
their unique Gas Detection as a Service solution known as iNet®. It also incorporates the leading technologies and processes of Accenture, AeroScout and Cisco. The solution is designed to continuously monitor employees working in plant environments across oil & gas, chemicals, petrochemicals, metals, mining, forest products and utilities.
The Ventis LS has the ability to detect one to four gases, including H2S, O2, LEL, CO, SO2 and NO2. In potentially hazardous conditions, the instrument alerts users through audible, visual and vibrating alarms. The instrument’s gas level information is then
transmitted over Cisco’s Unified Wireless Network using the gas detector’s integrated Wi-Fi Tag from AeroScout. The gas detection information is then sent to a control room, where an operator can react to the data. Because of the gas detector’s wireless technology, the operator can quickly locate the employee in danger, and organize rescue operations. A separate alert would be sent to the control room if lack of motion is detected or if the individual activates the detector’s panic button.
The Accenture Life Safety Solution extends itself beyond the plant’s confines. Operators can go outside of the plant with the same functionality using a combination of Wi-Fi and cellular communications.
The solution was initially field tested at two units at Marathon Petroleum Corporation’s Robinson, Ill., refinery. After successful testing, it was later deployed through the remaining refinery units, tank farm and outside the refinery fence line to include remote workers.
“Our deployment of this pioneering solution follows extensive evaluation of its functionality and costs,” said Don McCord, operations manager, Illinois Refining Division, MPC. “ The tested solution gives our workers a greater sense of confidence that their safety is being monitored in ways that have never been possible before in our industry. In addition, its proven cost effectiveness has allowed us to deploy the solution across the entire refinery.”

Is the gas mixture right? With the new gas analysis device MFA 9000 by WITT-Gasetechnik (gas technology) from Germany this question can now be answered in more detail by quality inspectors and service technicians than previously.
The analyser that can be used for a vast multitude of applications is now capable of determining the composition of 13 mixtures from respectively two gases. The MFA 9000 analyses the common technical gases of nitrogen, carbon dioxide, argon, hydrogen, helium as well as methane. Operation is practically infallible: for WITT a selector lever with three keys is covers it all. In the digital display the measuring result will be shown in percent in respect of the gas combination or as ppm share (parts per million). "In contrast to other devices only the mixed gas to be determined is required for a measurement," informs the director of the sales department, Martin Bender. "The user thus does not need an additional reference gas."
New Gas Leak Detector is Pure Gold
Sensit’s (USA) Gold G2 is a portable Multi-Gas Leak Detector and Confined Space Monitor for combustible gas readings in PPM, LEL and/or percent volume, as well as a variety of toxic sensors and oxygen. This unit displays Up To 4 Gases Simultaneously ( LEL - %volume and PPM optional, oxygen, carbon monoxide, hydrogen sulphide and, as an optional extra, hydrogen cyanide)
Gold G2 includes a fast sampling internal pump and digital ‘tick’ control – to ensure rapid sampling and detection. Operators can easily read the instrument as it includes a bright, graphic display with LED warning lights as well as a loud audible alarm. Low cost, long life sensors help ensure a rapid return on investment. The unit also includes internal memory and exceptional water protection.
The Gold G2 is widely used by natural and propane gas companies, gas exploration and transmission organisations, chemical and petrochemical plants, fire and hazmat services and HVAC contractors. The instrument is used for combustible leak detection, gas leak surveys, underground leak pinpointing carbon monoxide investigations, confined space monitoring, combustible gas detection and pipeline purging.

Crowcon Portable Gas Detector used by BBC Film Crew on Indonesian Volcano
A BBC film crew filming sulphur miners in the crater of an active volcano used a Crowcon (UK) Tetra 3 portable gas detector to warn them of dangerous levels of hydrogen sulphide (H2S). The crew were filming in Indonesia as part of the BBC’s landmark ‘Human Planet’ series which explores mankind’s relationship with nature in the world today.
During filming the crew were engulfed in a cloud of HS gas and had to quickly don gas masks (no such safety measures are used by the miners). They measured the gas concentration with the Tetra 3, which immediately went into alarm mode and showed a concentration of194 ppm – almost 40 times the safe breathing level. The corrosive gas quickly ate into the cameras, all of which promptly broke down.
Human Planet crews filmed in around 80 locations worldwide, using HD cameras to film from the air, from the ground and underwater. The result, according to the BBC website, is a “cinematic experience” created by world-class natural history and documentary camera crews and programme makers.
Crowcon’s lightweight, portable Tetra 3 combines extremely rugged design with small size and simple operation. Designed for use in the most demanding environments, it has simple, single button operation, even with a gloved hand. Monitoring oxygen, toxic and flammable gases, the unit has a top mounted, backlit display showing all gas readings, diagnostics and battery life.
If a hazard is detected, the Tetra 3 gives rapid and effective warning with a powerful 95 dBA audible alarm, an extremely bright red/blue LED visual warning, and by vibrating. More information about the tetra 3 can be found on Crowcon’s website.....

Toxic and Combustible Gas Monitoring Systems
Monitors available for combustible gases, organic solvents (ppm and % LEL) and a wide range of toxic gases
Sensor/Transmitters 24 Vdc Powered, 4-20 mA Output
Gas Monitor with Internal Sampling Pump
The measurement follows the principle of thermal conductivity, a quick and precise method, with unlimited useful life of the measuring cell. As quickly as one second, is the time taken for the first result to be given. The deviance from the final value of the measuring range is only around one percent. The calibration is done by means of a standard 2-point calibration or in simplification with one gas. Due to its compact dimensions of just 240 x 231 x 230 mm (w x h x d) the new MFA 9000 can be used mobile, 230 V are needed for operation. The gas pressure may be in the range from 1.5 to 20 bar; the flow rate is 40-150 Nl/h.
Those who want to use the antirust stainless steel analyser permanently and stationary, will be served excellently: the MFA 9000 is capable of alarm functions, detects measuring errors and delivers its data via an RS232 interface on a PC by which the device can be completely controlled and even calibrated as well. Furthermore, an outlet with 4-20 mA is provided, which can be optionally expanded.
