Principle
Measuring temperature and dissolving oxygen simultaneously, the instrument uses a polarographic dissolved oxygen Electrode. For measurement, the Electrode operates at a polarized voltage and measures the dissolved oxygen concentration by detecting the current generated by the diffusion of oxygen molecules through the diaphragm to the cathode. The instrument has a built-in microprocessor, uses digital filtering and slip technology to process the signal, and has automatic temperature, salinity, and pressure compensation to improve measurement accuracy and Response speed.
Applications
Aquaculture, water monitoring, wastewater treatment, environmental monitoring, education, scientific research
Steps
1. Turn it on and check the status of the instrument.
2. Connect the dissolved Oxygen electrode.
Electrode is polarized in a special calibrated sleeve (about 3-5 minutes).
4. Calibrate as needed (Automatic calibration function).
5. Electrode is placed in the sample to be tested for measurement.
6. Read and record measurement data (dissolved oxygen concentration, Saturation, temperature, etc.).
7. After the measurement is completed, the data can be exported through the USB interface or wirelessly printed through Bluetooth (optional).
8. Electrode clean and store properly.
Notice
* Do not use the instrument under conditions exceeding the Ambient Temperature (5~ 40 ° C) and Humidity (5~ 85% relative humidity).
* When replacing Electrode sensitive film, please use a special combined diaphragm cap and tighten it.
* When calibrating, make sure to use a dedicated Electrode calibrating sleeve.
The instrument is IP54 dust-proof and splash-proof, but not completely waterproof. Please avoid immersion in water.
* Please use the specified charging method to charge the built-in lithium battery.
* During measurement, ensure Electrode Response Time (90% Response in about 30 seconds) and wait for the reading to stabilize.
* When performing salinity and air pressure compensation, parameters can be entered manually as required.
* Regularly check the Electrode status, the instrument can intelligently judge to prompt the user.
When storing and transferring data, it can be operated through a USB stick, and the data format is compatible with Excel software.
