ANEMOMETERS
Bluetooth Anemometer
Wirelessly display, log, and transfer readings.
Sper Scientific’s Bluetooth® Anemometer Meter is small, light, and simple to use. Simultaneously displays air temperature in °C or °F, and air velocity in 5 units of measure, on the meter’s large 1-½” high backlit display. Features minimum and maximum hold (peak), data hold and moving average functions.
The meter offers the convenience of Bluetooth® for wireless communication with free iOS and Android Apps. Results can also be remotely viewed on your smartphone in real time, saved and exported. This enables the meter to be used as a remote wireless probe and as a data logger. Comes ready to use with instructions, tripod screw, and a 9V battery. Replaceable snap-in anemometer vane is available.

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.
