REED R9905 Data Logging Indoor Air Quality Meter

REED R9905 measures carbon dioxide (CO2), temperature, humidity and automatically calculates time-weighted average (TWA) and short-term exposure Limit (STEL)

The R9905 features a Nondispersive Infrared (NDIR) CO2 sensor for stable, accurate readings and the option to track live measurements via software.

This data logging Indoor Air Quality (IAQ) Meter has the ability to record samples on internal memory and keep track of registered readings with a time and date stamp.

Features:                

• Simultaneously monitors carbon dioxide (CO2), relative humidity and temperature
• Calculates time-weighted average (TWA) and short-term exposure limit (STEL)
• Low-drift NDIR CO2 sensor for stable and accurate readings
• Temperature and relative humidity measurements help determine thermal comfort
• Easy-to-read backlit LCD display
• User adjustable audible alarm
• Data hold, Max/Min and Average functions
• Record up to 32,000 datapoints and keep track with internal time and date stamp
• User selectable sampling rate from 1 to 60 mins
• Low battery indicator and auto shut-off
• Includes: USB cable, hard carrying case and batteries
• NIST Traceable Certification Available
• R9905 KIT includes 33% + 75% Humidity Calibration Standards
