REED R9980 Humidity Calibration Kit (33% and 75%)
Kit includes the R9933 (Humidity Calibration Standard, 33%) and R9975 (Humidity Calibration Standard, 75%). For use with REED R6001, R6200, SD-3007, R9900 and 8706.
Measures carbon dioxide (CO2), temperature, humidity and automatically calculates time-weighted average (TWA) and short-term exposure Limit (STEL).
REED R9905 Offers
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. The R9905 features a Nondispersive Infrared (NDIR) CO2 sensor for stable, accurate readings and the option to track live measurements via software.
Features
- Triple LCD display simultaneously monitors carbon dioxide (CO2), temperature and relative humidity
- 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
