Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). Ideal for monitoring indoor air quality in homes, offices classrooms, hotels or anywhere air quality is important. Fresh air is especially important to help lessen the spread of contagions and maintain a healthy environment.
Provides audible alarms for CO2 threshold. Maintenance free sensor ensures long-term accuracy, stability and reliability. The compact design features a large display with a bar graph indicating CO2 trend for up to 24 hours. 3 backlight colors indicate air quality status with four additional user selectable backlight color choices. Calibrates easily to fresh air and comes with a USB power cable. Will stand on a desktop or can be wall mounted.

Indoor Air Quality Monitor
Large display continually monitors the primary IAQ (Indoor Air Quality) parameters:
- Air Temperature
- RH
- CO2
Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). This instrument is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of CO2 (carbon dioxide) such as offices, factories, classrooms, hospitals and hotels. Recalls min/max CO2 levels and provides visual alarms for maximum CO2 threshold. Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long-term accuracy, stability and reliability.

Bluetooth IAQ Anemometer
- CO2
- Air Temperature
- Humidity
- Air velocity & volume
- Dew Point
- Wet Bulb Temperature
This unique anemometer allows you to monitor both air flow and indoor air quality at the same time.
Backlit dual display enables you to choose between an upper display of air velocity, RH or CO2 and a lower display of air temperature, air volume, dew point or wet bulb temperature. Calculates min/max, multi-point and time weighted average on all parameters and has a hold function. View readings on your smartphone in real time via Bluetooth with free iOS and Android apps and export a summary the data together for later analysis. The app will also superimpose current readings of all parameters on your smart phone photo of the object being measured. Simple user calibration of CO2 and RH.
Also enables input of air pressure for accurate compensation of CO2 measurements. The CO2 sensor uses NDIR (non-dispersive infrared) waveguide technology to ensure long-term accuracy, and reliability. Comes in a hard carrying case with 4 AAA batteries.
Optional Air Cones
Air cones come in a set with one round cone for vents smaller than 7 ½” diameter, and one square cone for vents smaller than 12 ½” x 12 ½”. When attached to the cone the meter automatically calculates air volume without the need to input vent size. The optional extension rod can be used with the meter alone, or the cone, eliminating the need for a ladder.
