The CMA wireless dissolved oxygen sensor measures oxygen levels in liquids from 0 to 50 mg/l using optical technology based on luminescence quenching. The sensor provides fast, reliable and oxygen-consumption-free measurements, which sets it apart from traditional electrochemical sensors.
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 dissolved oxygen 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).
Technical specifications:
-Measuring range: 0 .. 50 mg/L
-Resolution: 0.01 mg/L
-Accuracy: 0 – 10 mg/L < ± 1% / 10 – 20 mg/L < ± 2%
-Warranty: 24 months
-OLED display: 0.96" 128 x 64px
-Maximum sample frequency: 1 Hz
-Storage and operating temperature: between 0 and 50 °C
-Response time: ~ 65 s to reach approximately 63% of the final value
-Battery life: 6 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 under downloads.
Suggestions for biology and chemistry practicals:
-Practical on water quality. Oxygen is essential for life and indispensable for countless aquatic animals.
-Measuring dissolved oxygen in an aquarium with different combinations of plant and animal species
-Measuring changes in dissolved oxygen concentration as a result of photosynthesis and respiration in aquatic plants
-Measuring dissolved oxygen concentration in a stream or lake study to assess the extent to which the water can support different species of plants and animals
-Measuring the biological oxygen demand (BOD) in water samples containing organic material that consumes oxygen during decomposition
-Determining the relationship between the concentration of dissolved oxygen and the temperature of a water sample.
