The REED Instruments R9910SD-NIST is an advanced environmental monitoring solution designed for rigorous indoor air quality (IAQ) assessments.
This high-performance instrument simultaneously tracks Carbon Dioxide (CO2), Carbon Monoxide (CO), Oxygen (O2), Relative Humidity, and Temperature. To meet the demands of regulated industries and safety audits, this model includes a Traceable Calibration Certificate, ensuring your data is accurate, reliable, and compliant with international standards.
Comprehensive Sensor Array: Utilizes dedicated, high-sensitivity probes for gas detection and environmental monitoring, including calculations for Dew Point and Wet Bulb temperatures.
SD Card Data Logging: Automatically record time-stamped measurements onto an SD card (sold separately). Data is saved in a universal Excel-compatible format, eliminating the need for complex proprietary software.
Documented Compliance: The included NIST-traceable certificate provides the paper trail required for ISO quality management systems and professional safety inspections.
User-Adjustable Sampling: Configure data logging intervals from 1 second to 9 hours to capture everything from rapid environmental fluctuations to long-term baseline trends.
Industrial Hygiene Compliance: Conduct certified safety audits in manufacturing plants and warehouses to monitor oxygen levels and gas exposure.
Professional IAQ Consulting: Provide clients with documented proof of air quality standards in commercial buildings, hospitals, and schools.
HVAC System Validation: Use certified humidity, temperature, and dew point readings to verify the performance of large-scale climate control systems.
Confined Space Monitoring: Check for adequate oxygen levels and the presence of CO before personnel enter sensitive work areas.
Research & Development: Utilize high-accuracy data logging for environmental studies where traceable measurement integrity is non-negotiable.
