Hana portable dissolved oxygen analyzer HI98193

Rapid conversion between dissolved oxygen and saturated dissolved oxygen

Automatic compensation for atmospheric pressure (altitude), accurate and rapid measurement of dissolved oxygen mg/L (ppm) and saturated dissolved oxygen%.

Laboratory Standards (GLP) Function

Query GLP data, including the date, time, pressure, calibration value, temperature, and salinity value of the last calibration, to ensure data security

Biochemical Oxygen Demand (BOD) Setting and Display

By using BOD parameters and display settings, all BOD data can be quickly saved and displayed on the LCD screen for easy retrieval and viewing

Biochemical Oxygen Demand (BOD)

The BOD value is automatically calculated by measuring the difference between the initial dissolved oxygen value and the final dissolved oxygen measurement value (mg/L), and the BOD measurement value is displayed in mg/L (ppm).

The amount of dissolved oxygen consumed by microbial metabolism is an important indicator indirectly indicating the degree of organic pollution in water bodies. It is defined as the amount of free oxygen consumed by aerobic microorganisms to oxidize and decompose organic matter per unit volume of water under aerobic conditions, expressed in ppm (mg/L). The higher the value, the more organic pollutants in the water, and the more severe the pollution.

The international standard is to cultivate for five days in a 20 ° C incubator as the standard for determining biochemical oxygen demand, which is BOD5.

Oxygen consumption rate OUR

The measurement result is based on the milligrams of oxygen consumed per liter and per hour.

To determine the oxygen consumption rate of activated sludge, it is necessary to analyze whether it contains non-toxic substances, load conditions, and sludge discharge balance, in order to better set and control the sewage treatment process

Specific oxygen consumption rate SOUR

The measurement results are measured in milligrams of oxygen consumed per hour per gram of volatile suspended solids.

The quantitative indicator for evaluating the stability of activated sludge in sewage treatment refers to the oxygen consumption per unit mass of activated sludge per unit time; SOUR is an important biochemical indicator in experimental studies such as microbial cultivation. The SOUR (respiratory intensity) of microbial cells refers to the amount of oxygen consumed per unit weight of cell per unit time.

HI764073 Clark type polarographic dissolved oxygen electrode, capable of measuring various dissolved oxygen levels ranging from 0.00.00 to 50.00 mg/L (ppm) and saturated dissolved oxygen levels of 0.0 to 600.0%. Equipped with a built-in thermistor temperature sensor and automatic temperature compensation from 0 to 50 ° C, it is tailored for the HI98193 dissolved oxygen analyzer and is suitable for industries such as environment, wastewater treatment, water analysis, industry, and aquaculture.

The dissolved oxygen electrode body is made of PEI material to improve electrode durability. The polarographic sensor technology is based on the Ross and Clark polarographic measurement method. The dissolved oxygen electrode consists of a cathode and an anode component. The dissolved oxygen electrode is designed with a customized protective cover, suitable for laboratory and field applications in any environment.

The dissolved oxygen electrode uses a spiral dissolved oxygen membrane installation form, making it easy to replace and maintain. The HI76407A/P dissolved oxygen membrane is composed of durable plastic material and polytetrafluoroethylene (PTFE) oxygen permeable membrane. Each dissolved oxygen membrane is easily filled with HI7041S specific dissolved oxygen filling electrolyte and installed on the dissolved oxygen electrode.

The HI76407A/P dissolved oxygen membrane separates the dissolved oxygen electrode cathode and anode from the sample to be tested. Oxygen diffuses through the dissolved oxygen membrane and interacts with the dissolved oxygen electrode polarographic system to generate a current proportional to the oxygen concentration; The dissolved oxygen membrane is composed of durable plastic material and polytetrafluoroethylene (PTFE) oxygen permeable membrane. Each dissolved oxygen membrane is easily filled with HI7041S specific dissolved oxygen electrolyte and installed on the dissolved oxygen electrode;

Reminder: When the HI76407A/P dissolved oxygen membrane is not in use, the shelf life of the standard storage conditions is two years. After installation and use, it is recommended that users replace it every 6 months in a regular measurement environment.

HI7041 dissolved oxygen filling solution is customized for Hanna's polarographic dissolved oxygen electrode development. The use of the correct dissolved oxygen electrode filling solution is crucial for the performance of the dissolved oxygen electrode.

Hana's high-quality NaCl solution with unique configuration is used in conjunction with PTFE (polytetrafluoroethylene) dissolved oxygen membrane and polarographic dissolved oxygen electrode; Using polarographic techniques, an external voltage is applied to the platinum cathode, silver anode, electrolyte solution, and gas permeable membrane to establish a current proportional to the oxygen concentration in the solution

Multiple packaging specifications to meet different user needs:

HI7041S specification: 30mL × 4, dropper bottle design, convenient for users to add quickly and easily, avoiding waste

HI7041M specification: 230mL; HI7041L specification: 500mL

HI7040 Zero Oxygen Calibration Solution

In order to ensure the accuracy and precision of dissolved oxygen measurement data, dissolved oxygen calibration is crucial. HI7040 customizes a dedicated dual combination zero oxygen calibration solution, allowing users to quickly and accurately perform zero oxygen calibration

All instruments and accessories of the dissolved oxygen analyzer are neatly packaged in a sturdy carrying case to ensure that users have everything they need for easy and quick on-site measurement.
