The \u003cstrong\u003ePro-Tech 8505 Commercial CO Alarm\u003c\/strong\u003e is designed for employers: it alarms based on the workplace exposure limits set by OSHA, NIOSH, ACGIH and Cal\/OSHA, and it shows the CO level continuously from 9 ppm.\u003c\/p\u003e\n\u003ch2\u003eWhy It Matters\u003c\/h2\u003e\n\u003cp\u003eWorkplace CO limits are based on exposure over time, not a single reading.
