Description
EziLab Desktop Dissolved Oxygen Meter EZL-DDO121 delivers precise dissolved oxygen concentration and saturation measurements for aquaculture testing, wastewater treatment evaluation, environmental laboratories, scientific research institutes, and educational setting applications. Automatic temperature, salinity, and air pressure compensation ensures stable dissolved oxygen analyzer results across varying test conditions, while high-re display enhances data visibility during continuous monitoring. Rapid sensor response reduces overall analysis time, and excellent measurement stability minimizes drift during extended laboratory studies. Built for long-term performance across demanding analytical environments without frequent recalibration. EziLab's Lab Equipment and water quality analyzers present the complete dissolved oxygen analyzer and desktop DO measurement range for laboratory and research use.
