Reed R9900-NIST Datasheet (PDF)

Measures carbon dioxide (CO2), temperature, humidity and automatically calculates dew point and wet bulb temperatures.

 

REED R9900 Offers

This IAQ (indoor air quality) meter simultaneously monitors carbon dioxide, relative humidity, and temperature. The R9900 is capable of automatically calculating wet bulb and dew point temperatures as well as statistical TWA and STEL averages.

Features

• Triple LCD display simultaneously monitors carbon dioxide (CO₂), relative humidity and temperature
• Automatically calculates dew point and wet bulb
• Calculates statistical weighted averages of TWA (8 hour time weighted average) and STEL (15 minute short term exposure limit)
• User adjustable audible alarm
• Data hold, Max/Min and average functions
• Low battery indicator and auto shut off
