| CO2/Temperature/RH/Datalogging Kit |
| Model 7001 D |
|
Equipped with Telaire's patented dual
beam Absorption Infrared® technology, the Telaire® 7001D Combines
the easy-to-use Telaire® 7001 with a pocket-sized Hobo® datalogger
from Onset Computer Corporation. The Telaire® 7001D is designed for
use in residential or commercial applications and now has the ability
to calculate and display the cfm/person ventilation rate as well as record
CO2, temperature, and RH data over time. The Telaire®
7001D is th eideal tool for identifying energy saving opportunities in
over-ventilated spaces, determining if air quality complaints are due
to insufficient ventilation, or locating th epresence of combustion fumes
generated from vehicles and appliances. The Telaire® 7001D comes with
everything you need to record CO2, temperature,
and relative humidity data and graph the information on a PC. |

About the CFM/Person Ventilation Rate Measurment The 7001 will calculate the outside air ventilation rate to a space based on the inside/outside CO2 differential readings. Outside readings can be established by measuring outside levels and holding the "enter" button on the sensor for 5 seconds. The outside reading can also be manually set using the - on-board keypad and display (default 400 ppm).Accurate interpretation of the Ventilation Rate Indicator requires a measuring 2 to 3 hours after occupancy has stabilized in a space or at a peak in daily CO2 concentrations. In other conditions the indicator may tend to over estimate ventilation rates. The ventilation Rate display assumes a people activity level in the measured space similar to an office type environment (1.2MET). If higher levels of activity are present the indicator may tend to under estimate ventilation levels. |
