    Oxygen monitoring from aerobic and anaerobic for toxicity test

    Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”

    Testing Fume Hood Flow Dynamics using SF6 as a Tracer Gas

    A safe laboratory environment requires an effective method for clearing toxic material from fume hoods. Since all handling of toxic materials is completed in these hoods, it is critical to have a procedure to evaluate their operation to assure adequate protection for laboratory workers. The InfraRan Specific Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood efficiency in accordance with ASHRAE and other standards. Manufacturers identify the flow dynamics (factors that...

    Gas monitoring instruments and systems for compressed breathing air

    Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line...

  • Odour measurement on industrial sites like waste water treatment plants (WWTP), landfill, compost plant...

    CairNet is a simple and efficient way to monitor processes and plant surroundings via a wireless communicating network and autonomous (solar panel and battery). CairNet surveys fugitive emissions of toxic gases or odourous gases around waste water treatment plants (WWTP), allowing you to react quickly to gas leaks. CairNet allows the wireless survey of hundreds of measurement points within a 200m radius of the wireless receiver for a much efficient installation cost. Cairpol systems can be used for fugitive...
