Measures carbon dioxide (CO2), temperature, humidity and automatically calculates time-weighted average (TWA) and short-term exposure Limit (STEL). This product includes a Traceable Certificate with full Data and Uncertainties.
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.
This product includes a Traceable Certificate with full Data and Uncertainties.
