12 Gas Detection New Durable Multi Gas Monitor Launched
Scott Safety (UK) has launched Protégé, a technologically advanced, hand-held, durable multi-gas monitor for detecting oxygen, combustibles, hydrogen sulphide and/or carbon monoxide in industrial, petrochemical and emergency situations. Certified to the highest possible global performance standards, Protégé is ergonomically designed to fit in the palm of the hand. Rugged but lightweight, Protege can be used in the harshest conditions but is suitable for use in every day working activities. With its small, efficient design and simple two-button interface, users can easily operate all of Protégé’s features with one hand leaving the other hand free. Protégé also features visual, audible and vibrating alarms, extensive data-logging and a large, backlit LCD screen. With Windows-based proprietary software, a variety of operating options can be configured for a multitude of uses and personal user preferences including; password control, alarm set points, calibration gas values and automatic zero calibration at start up. Data logging is based on event changes only, rather than automatic intervals, resulting in the capture of relevant analytics of workplace environments and usage while reducing the number of stored data points. Up to 7,000 significant events can be captured and stored for further analysis. This feature enables the end-user to focus on the data that is the most important to them. With its easily changeable sensors, Protégé can be configured in five different sensor combinations for use in multiple applications. It is perfectly suited for confined space applications when using the optional parasitic pump which does not require its own power supply. When configured with its optional pump, Protégé is transformed from a personal gas monitor into a confined space monitor.
Reader Reply Card No. 34 Accurate Measurement of Six Gases Simultaneously
Dräger (Germany) has expanded its range of multi-gas detection devices for personal protection. The X-am 5600 measures up to six gases simultaneously. It has a very long lifespan and due to its robustness is perfect for use in industry or supply and waste disposal. The X-am 5600 detects explosive, flammable and toxic gases, in addition to oxygen. The heart of the device is its infrared sensor, which can measure explosive gases, carbon dioxide or both. In comparison to catalytic sensors, the infrared measurements for explosion hazards cover a larger area. They monitor the measurement range to the lower explosion limit and detect the entire range up to 100 percent by volume of
methane, ethylene, butane, and propane. The CO2 sensor has a measurement resolution of 0.01 percent by volume and can detect even slight changes. The dual sensor is ideal for applications in which both substances may occur: it detects both carbon dioxide and explosive substances. Additionally, the infrared sensors do not depend on the content of the oxygen in the atmosphere. They can also be used in inertised environments. The operating range of the X-am 5600 can be expanded easily by adding it to the area monitor X-zone 5000 enabling the X-am 5600 to continuously monitor places where a gas leak is expected and pre-warn people before they enter the hazardous zone. The expected life cycle of the infrared sensors is more than eight years. In comparison, one catalytic Ex sensor must be changed after three to four years. The device should be calibrated once a year, while the catalytic Ex sensor has a recommended service interval of six months. A service life of five years is guaranteed for the electrochemical sensors for oxygen, carbon monoxide and hydrogen sulfide. The extended service life and lower maintenance requirements reduce the operating costs of the device. The X-am 5600 uses the proven features of the X-am 5000. The X-am 5000 also detects possible errors in defective parts and identifies them. The daily function test can be done with the bump-test station, requiring no external power supply, which means testing is decentralised.

New Rugged and Reliable Four-Gas Detector
BW Technologies by Honeywell (UK) introduces the newest member of the GasAlert family - the GasAlertQuattro. Rugged and reliable, the GasAlertQuattro four-gas detector combines a comprehensive range of features with simple one-button operation.
Simultaneously monitor and display H2S, CO, O2 and combustibles. With flexible power options, AA batteries or a rechargeable battery pack, the GasAlertQuattro is always ready for your shift. The large LCD with intuitive icons and backlight simplifies on-site auditing and compliance.
Bump test and calibration icons are clearly identifiable, and extralarge digits are easy to read in varying light conditions. The green LED confidence flash provides continuous visual confirmation of detector operation and compliance. The versatile GasAlertQuattro was designed for harsh environments. A durable exterior with reinforced bumpers and integral concussion-proof boot protect the detector. Suited to a wide range of industrial applications including general confined space entry, the GasAlertQuattro offers a simple, automatic calibration procedure and is compatible with BW’s MicroDock II automatic test and calibration system. With the GasAlertQuattro, seeing is believing.
