Alnor’s New IAQ Meters to Monitor Indoor Air Quality

Alnor, a leader in manufacturing test and measurement devices utilized for pneumatic parameters such as barometric pressure, moisture content, dew point, air velocity, air balancing, air velocity , air flow and temperature, have designed new IAQ (Indoor Air Quality) meter.

These IAQ meters solve numerous problems helping building owners, HVAC contractors, operators and consultants, in places such as factories, schools and other industrial and commercial buildings.

System performance can be examined by measuring relative humidity and temperature. The environment inside the building could be enhanced by measurement of relative humidity, CO₂ levels and temperature and more importantly to comply with mechanical or energy codes, or building rating systems, such as ENERGY STAR and LEED monitoring of these attributes is essential.

CompuFlow indoor air quality meters comes in three models, the CF910 for measuring CO₂; the CF930 for measuring CO₂, humidity, CO and temperature levels; and the CF920 for measuring CO₂, humidity and temperature levels. All the three models incorporate a large display, NIST-traceable calibration certification, a non-dispersive infrared (NDIR) sensor, a statistics function for calculating minimum, maximum and average values and can also read CO₂ in ppm, ranging between 0-5000. Two models, the CF920 and CF930 also have an additional feature of data logging.

The NIST calibration ensures that the readings noted and sent to the customers are exact, and help in eliminating bias in the device’s readings, especially over a range for continuous values. To sustain the integrity of the readings taken, recertification of the calibrated instrument is vital on a regular basis.
