DOPO2 – Probe USB Oxygen Sensor
The DOPO2-PRO system consists of a DOpO2 probe attached to a Bluetooth/communication interface module for industrial applications. Communication board supports
- 4-20mA analog output
- External temperature sensor interface
- Bluetooth for android devices
DOPO2-PRO system is equipped with a rechargeable internal battery that can be charged from a USB port and it runs for 8 hours when it is fully charged.
The user can connect it to a PC via USB and saves data in a Microsoft Excel format or use it with an android device through Bluetooth and saves his data in CSV format.
Similar to DOpO2, it can be configured with single-channel LED excitation and detection, and modulation frequencies up to 31.2 kHz. The on-board pressure transducer and thermistor measure atmospheric pressure and temperature.
