The wireless CO₂ gas sensor measures concentrations of gaseous carbon dioxide in the range of 0 to 5000 ppm. The sensor is equipped with an OLED colour display that shows sensor information and measured values. This makes the sensor suitable for use as a stand-alone measuring instrument.
This wireless CO₂ sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 Lite programmes/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
The sensor is designed exclusively for measuring gaseous CO₂ concentrations, not for measuring CO₂ in liquids. Never insert the sensor tube directly into a liquid.
It may take some time for the CO₂ measurement to stabilise, as the gas must diffuse through a membrane filter in the sensor probe. Because diffusion is a slow process, it may take a while for the sensor to accurately detect and measure the CO₂ concentration.
The CO₂ sensor element is protected from contamination by a membrane filter. Therefore, do not remove the metal cap from the sensor.
The CO₂ gas sensor is supplied with a factory calibration in ppm. The factory calibration is sufficient in most cases. You can also choose to calibrate your sensor by setting it to 400 ppm while measuring in fresh air.
Technical specifications:
-Measuring range: 0 .. 5000 ppm
-Resolution: 1 ppm
-Warranty: 24 months
-OLED display: 0.96" 128 x 64px
-Maximum sample frequency: 1 Hz
-Warm-up time: 3 minutes at temperatures between 20 and 30 °C
-Response time: ~ 65 s to reach approximately 63% of the final value
-Battery life: 4 hours when fully charged (rechargeable)
-Connection: Bluetooth 5, Low Energy (Mac, Android, iOS) Bluetooth 2.1, Classic (Windows) or USB-C 2.0
-All sensor specifications can be found in the Manual, see Downloads.
Suggestions for biology and chemistry practicals:
-Measuring CO2 levels (respiration) of small animals and insects
-Monitoring CO2 changes in a plant terrarium during photorespiration and photosynthesis in light/dark (combination with the light sensor)
-Measuring CO2 levels during cell respiration of peas or beans
-Measuring CO2 levels during yeast respiration
-Monitoring CO2 production during chemical reactions
-Measuring CO2 levels in the classroom
-Measuring CO2 changes due to decomposing organic material
