Application
Application of 8401 AZ Dissolved Oxygen Detector:
The portable 8401 AZ DO meter can measure the value of Dissolved Oxygen with unit of % or ppm or mg/l in liquid, which had been widely operation in the Water Quality Testing applications. It has the big LCD which can display the D.O. (Dissolved Oxygen) value and the temperature.
The 8401 AZ Digital DO Device can calibrate easily in the ventilation environment, welcome to refer the DO calibration procedure video from the following YouTube link.
The 8401 AZ Dissolved Oxygen Meter could link to PC via USB cable to capture the on-line data, and display the Dissolved Oxygen readings with real-time output. User can retrieve file, save the data for operating data analysis, record statistics....versatile functions according different purposes.
The 8401 AZ Digital DO Device could be the best Water Quality tester for all professional measuring purposes, including the LAB, water treatment business, Aquaculture, Aqua farm, swimming pool or other related industry.
The 8401 AZ Dissolved Oxygen Detector was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.

FAQ
【FAQ of AZ 8401 Handheld Dissolved Oxygen Meter with D.O. electrode】
Q1: How often should I calibrate the AZ 8401?
A: For optimal accuracy, calibrate before each use or daily. You should also recalibrate after replacing the membrane or when there are significant changes in temperature or altitude.
Q2: When should I replace the DO probe membrane and electrolyte?
A: Replace them if you notice unstable readings, slow response, or difficulty calibrating. Regular maintenance is recommended every 3–6 months, or immediately if the membrane is torn, fouled, or dry.
Q3: Can I use the AZ 8401 for BOD testing?
A: Yes. But please notice that while the AZ 8401 provides high-accuracy DO readings, it does not have a built-in BOD calculation mode. Users must design their own testing protocol to manually calculate the BOD value based on the results.
