Multi-Gas Monitors

GasAlertMicro 5 by BW Technologies

Providing protection from up to five potential atmospheric hazards including oxygen, combustible and toxic gases, GasAlertMicro 5 is unparalleled in its versatility, capability and overall value. BW’s newest addition to its water-resistant line of portable gas detectors has transformed the market with its matchless array of features.
Continuously monitoring and displaying concentrations of up to five gases, the compact and lightweight GasAlertMicro 5 was designed and engineered with an extensive host of applications in mind.

Features

• Integral concussion-proof boot
• Optional integral motorized pump option for remote sampling
• Powered by three AA alkaline batteries or a hot-swappable rechargeable battery pack
• Triple alarms (audible, visual and vibrating)
• Multi-language support in English, French, German, Spanish and Portuguese
• Large, user selectable backlit LCD
• Four alarm levels: Low, High, TWA and STEL
• Compatible with MicroDock II Automatic Test and Calibration Station
• Datalogging models store and recall event information
• Wide range of user selectable field options including password protection, safe and stealth modes.

Self-Tests

• Full function self-test confirms sensor, battery and circuitry integrity and audible/visual alarms on activation

Single-Gas Monitors

GasAlertClip Extreme Single Gas Monitor

BW Technologies has raised the bar for maintenance-free detection with the new GasAlertClip Extreme. Providing two years of protection from H2S, SO2, CO or O2, the water-resistant GasAlertClip Extreme has a built-in concussion-proof boot and is ideal for amphibious operations and high-moisture environments.

Equipped with two alarm levels and an internal vibrator, the GasAlertClip Extreme now features four visual LEDs, and a high-output audible alarm.. The large, alphanumeric display provides instant notification of gas alarms, test status, life remaining (months then days then hours) and peak (maximum) exposures encountered.

The GasAlertClip Extreme`s advanced microprocessor performs a full function self-test automatically on startup and on demand to verify sensor, circuit and battery integrity, as well as audible/visual alarm operation.

Generating a permanent record of gas alarm events has never been easier. The GasAlertClip Extreme allows for effortless transmission of stored event data to a cordless printer or a PC for review and analysis.

Despite being loaded with features, the GasAlertClip Extreme is compact and light, which makes it comfortable to wear. Clip it to your lapel, pocket, belt or hardhat for unequalled protection.

Available as a 3-year monitor for CO or a 2-year monitor for H₂S, CO SO₂ or O₂

Fixed Systems

BW Technologies Rig Rat III

Rig Rat III wireless, multi-point detection system

The Rig Rat III wireless multi-point system continuously monitors for toxic gases, combustibles and oxygen hazards. The self-contained, intrinsically safe site controller is equipped with built-in alarms for instant notification. Independent power, wireless digital signal transmission and plug-in options provide total flexibility. Engineered for maximum cost-effectiveness, the Rig Rat III transmits real-time digital data as far as 1.8 miles (3 km). Installation costs are reduced by up to 75% through eliminating the need for cabling, wiring, conduit and trenching.
The solar-capable Rig Rat III is completely modular in design, with plug-in ports for all field interfaces, including remote sensors, remote alarms and relays. Add, change or reconfigure system components as your requirements evolve.

The Rig Rat III’s microprocessor-based operation and forefront sensor technology assures peerless reliability and performance. The Rig Rat III is the ultimate in stand-alone detection.

Field Tough: Rig Rat III provides unwavering performance in extreme conditions, from deserts to the Arctic.
Easy Installation: Equipped with a rugged weatherproof stainless steel enclosure and built-in mounting flanges, simply mount the detector to the wall and supply power.
Facility Monitoring: Multi-point systems can be expanded to 100 or more individual monitoring points, with each detector coded to a separate channel.
Perimeter Monitoring: The most cost-effective solution to perimeter monitoring.
Portable Monitoring: The only portable, multi-point monitoring system in the world–field-proven on mobile work sites, such as drilling/service rigs, HAZMAT and disaster response teams.
Detector Sub-Site Controller: The detector can activate remote relays and a solenoid driver to control emergency shutdown devices (ESD), building ventilation systems and other field interfaces.

Features

• Independent power and radio signal transmission
• Microprocessor operation ensures performance and reliability
• Flexible power choices–battery, solar, 110/230 VAC
• Encoded digital signal transmission up to 1.8 miles (3 km)
• Real-time LCD readouts for all detectors and sensors
• Simple, straightforward, user-friendly operation
• Modular engineered design
• Status panel advises all features and functions
• Plug-in ports for remote sensors and options
• Dual alarm levels for each sensor (adjustable)

NOTE: Listed below are all the parts and pieces of the Rig Rat III. This is primarily designed for users who already have a unit in service and are looking for replacement parts or looking to expand their already existing system. Because there are so many different options and features, we highly recommend that a facility that is looking at installing a new system from scratch call our instrumentation specialist at 1-800-213-7092 so that we can assist you.
