CO Sniffer® Portable Detector  -- 

The Sniffer portable carbon monoxide detector offers versitile, fast CO detection of up to 2000 ppm where-ever and when-ever you need it. Use the Sniffer's powerful internal pump for "spot detection" of the CO sources in areas such as furnaces, garages, stoves, and fireplaces. 

With the optional Breath Analysis Module (BAM), the Sniffer becomes a powerful tool in determining the presence and level of CO within the blood stream and helps determine emergency response to personnel exposed to CO. A simple attachment to the Sniffer and the BAM returns CO levels in under one minute. 

    The Sniffer's (4) C-sized batteries provide up to 14 hours of continuous operation 

Gas Pointer II MPD for Gas Utilities  -- 

In ambient air or high temperature flue gas analysis, the Gas Pointer II provides an instrinsically safe option for gas utility customer service personnel. 

The large LCD display auto-ranges from %LEL to %GAS as gas concentrations change and PPM leak detection can be selected with the push of a button. An internal pump continuously draws a sample thru either 10" or 30" probe assembly and a high temperature probe is available for use when measuring flue gas. Optional audible and visual alarms enhance the use of the Gas Pointer II in confined space entry applications. 


 Its ideal for: 

  • locating natural gas or propane leaks around pipes, fittings, and appliances 
  • measuring excessive levels of carbon monoxide in heating and ventilation systems 
  • sampling confined spaces for entry 

Canary II ® Single Gas Portable Monitor  --

    • Detects toxic or flammable gases 
    • Highly visible and audible alarms 
    • Confidence ‘blip’ confirms safe working conditions 
    • Fully adjustable alarm trigger levels 
    • Time weighted average alarm facility for 15 min and 8 hour exposure levels. 
    • Rugged Triax TM casing will not break,crack or shatter 
    • Easy and safe to use 
    • Comprehensive PC Interface 

Portable, Multiple Gas Detection Instruments

Scout represents the next generation of portable gas detection.  Its innovative design and advanced features make it the most versatile instrument of its kind.  The SCOUT's ergonomic design and many of its features are truly unique...

Exclusive Advanced Battery Management Technology (ABMTTM) feature provides up to 50 hours of runtime and, a wireless inductive battery charger charges SCOUT faster and easier than ever.  Unlike many other similar instruments, Scout’s battery pack is simple to release without having to unscrew or remove components.

With a "no case openings design" and wireless inductive charging and datalogging system the SCOUT has no case openings for moisture to penetrate and corrode its internal components.

The foolproof  IntellishutterTM lets users quickly change from diffusion mode to sample draw mode “on-the-fly” without tools.  The IntelliShutter's position is sensed to prevent incorrect operation and a sample draw port only permits a probe to be connected when the shutter is closed.

An easy to use, modular platform, the SCOUT can be configured for any level of user and stores up to 100 customized profiles for work teams.  Complete component modularity means SCOUT can be upgraded to any level of sophistication or serviced in-the-field without specials tools or complex procedures.

BodyGuard 4® Four Gas Portable Monitor  -- 

BodyGuard 4® Designed for use in a variety of industries, the BodyGuard 4 provides for a wide range of available gas combinations allowing the instrument to be customized to your application’s requirements. BodyGuard 4 monitors four gases simultaneously in a compact, lightweight, and rugged monitoring package. 

Each BodyGuard 4 is equipped with datalogging and convenient downloading to a PC. Power is supplied by three AA batteries but an optional metal hydride battery pack will extend continuous operation to up to 12 hours. An optional pump permits pre-entry sampling and the instrument comes complete with a limited lifetime warranty and 4 years free calibration.
