Q: What makes a carbon monoxide monitor suitable for industrial use?
A: Industrial monitors feature rugged construction, wider measurement ranges (typically 0-1000+ ppm), advanced sensor technology, multiple output options, and certifications for hazardous locations. They’re designed for continuous operation in challenging environments.
Q: How often should industrial CO monitors be calibrated?
A: Most manufacturers recommend calibration every 3-6 months, with bump tests performed monthly. High-use or critical applications may require more frequent calibration. Always follow manufacturer recommendations and regulatory requirements.
Q: Can I use residential CO detectors in industrial settings?
A: Absolutely not. Residential detectors lack the range, durability, and certifications required for industrial environments. They won’t provide adequate protection and may violate safety regulations.
Q: What’s the typical lifespan of an industrial CO monitor?
A: The monitor body typically lasts 5-10 years with proper maintenance. Electrochemical sensors generally require replacement every 2-3 years, depending on usage and environmental conditions.
Q: How many monitors do I need for my facility?
A: This depends on facility size, layout, processes, and risk assessment. General guidelines suggest monitors every 4,000-10,000 square feet in open areas, with additional units near potential sources and in confined spaces.
Q: What’s the difference between fixed and portable monitors?
A: Fixed monitors provide continuous area monitoring, while portable monitors offer personal protection and flexibility for different locations. Most industrial facilities use a combination of both for comprehensive coverage.
