Indoor Air Quality Meter

Sper Scientific 800046 Indoor Air Quality Meter: Your Solution for Healthier Indoor Environments

Ensure optimal Indoor Air Quality (IAQ) in any public space with the Sper Scientific 800046 IAQ Meter. This device is essential for monitoring areas where high levels of CO₂ (carbon dioxide) can accumulate, posing health and safety risks.

Why Monitor Indoor Air Quality? Poor air quality is more than just uncomfortable; it can lead to tangible health issues like fatigue, difficulty concentrating, headaches, and even contribute to Sick Building Syndrome. By monitoring air quality, you can proactively address potential problems and create a healthier, more productive environment. This instrument is ideal for maintaining IAQ standards in crowded or enclosed spaces such as:

• Offices and factories
• Classrooms and schools
• Hospitals and healthcare facilities
• Hotels and hospitality venues

The meter's parameters are also perfect for testing and verifying the performance of HVAC equipment, ensuring your systems provide adequate ventilation.

Comprehensive and User-Friendly Monitoring The Sper Scientific 800046 provides a complete picture of your environment on a single, easy-to-read backlit display. It simultaneously shows:

• CO₂ Level: From 0 to 5000 ppm
• Humidity: From 0 to 100% RH
• Air Temperature: From 14 to 140ºF (-10 to 60ºC)

For more detailed analysis, you can toggle the display to show Dew Point and Wet Bulb Temperature. The device also calculates critical exposure metrics like TWA (Time-Weighted Average) and STEL (Short-Term Exposure Limit), providing deeper insights for occupational health and safety assessments.

Advanced Features for Professional Use

• NDIR Sensor: Equipped with NDIR (non-dispersive infrared) technology, the meter ensures long-term accuracy, stability, and reliability for CO₂ measurements.
• Audible Alarms: Set custom threshold alarms to receive immediate audible alerts when CO₂ levels exceed safe limits.
• Data Functions: Includes min/max/avg readings and a hold function to freeze the current display for easy recording.
• Easy Calibration: Features a simple user calibration process for both CO₂ and RH to maintain accuracy over time.
• Data Logging: Connect the meter to a computer using the optional USB Cable (840054) and Data Acquisition Software (840052) to stream and record data for analysis and reporting.

What's Included: The meter comes complete with a hard carrying case for protection and portability, along with 4 AA batteries to get you started right away. An optional AC Adapter (840027) is available for continuous, long-term monitoring.

Understanding CO₂ Levels (ASHRAE Standards):

• 250–350 ppm: Normal background level for outdoor air.
• 350–1,000 ppm: Typical level in occupied spaces with good air exchange.
• 1,000–2,000 ppm: Level associated with complaints of drowsiness and poor air quality.
• 2,000–5,000 ppm: Level linked to headaches, sleepiness, stale air, poor concentration, and increased heart rate.
• >5,000 ppm: Considered the workplace exposure limit (8-hour TWA). Higher levels can lead to serious oxygen deprivation, resulting in permanent brain damage, coma, or even death.
