• [Accuracy Instrument] DO9100 is an accuracy instrument for measuring dissolved oxygen and temperature. With built in microcomputer processor to calculate and compensate all measurement data related to dissolved oxygen and temperature.
• [Probe] A membrane with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode and allows oxygen to pass through the membrane to react.
• [Digital Display Screen] It is equipped with a clear digital display screen, which is convenient for reading data. If not in use, it will automatically shut down in 8 minutes, with low battery prompt, detachable probe, and easy to replace.
• [Temperature Compensation Function] The solubility of oxygen will be affected by temperature, atmospheric pressure and salinity. Our instrument has a temperature compensation function, which can meet normal use.
• [Wide Application] Suitable for measuring the dissolved oxygen level and temperature in aquariums, swimming pools, pond, freshwater aquaculture, marine aquaculture, school teaching experiments, laboratory sterile environment, aquaculture, scientific research and other fields.
