Description
The sensor features a color OLED display that shows sensor information and readings. This makes it suitable as a standalone measuring instrument.
This wireless CO2 sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks, and mobile devices (Android and iOS).
The Dissolved Oxygen sensor is supplied calibrated with a factory calibration in mg/L. When working with the Coach program the pre-defined calibration can be shifted by using the Set to Value option.
Proper care and storage of the Dissolved Oxygen sensor are essential to maintain accurate measurements and extend the sensor’s lifespan. Download the product manual for more information about how to do this.

Suggested biology and chemistry experiments:
- Water quality experiments: dissolved oxygen levels are used as a general indicator of water quality. Oxygen is essential to life and vital for countless aquatic forms.
- Monitoring dissolved oxygen in an aquarium containing different combinations of plant and animal species
- Measuring changes in dissolved oxygen concentration resulting from photosynthesis and respiration in aquatic plants
- Measuring dissolved oxygen concentration in a stream or lake survey, in order to evaluate the capability of the water to support different types of plant and animal life
- Measure Biological Oxygen Demand (B.O.D.) in water samples containing organic matter that consumes oxygen as it decays
- Determine the relationship between the dissolved oxygen concentration and the temperature of a water sample
