The "HWDP-511/511F" is a high-functionality, high-performance dissolved oxygen meter (DO meter) that enhances the bubble-washing type DO meter "DOP-501." It allows for various parameter changes and can perform various correction processes such as altitude correction and chloride ion correction. When using the bubble-washing holder, the influence of bubble washing is extremely small, allowing measurements to be taken even during washing, enabling continuous cleaning and reducing maintenance frequency. 【Features (excerpt)】 ■ Stable measurements can be achieved even in still water due to forced flow to the electrode (when using the bubble-washing holder) ■ Simple structure due to flow-based cleaning, making maintenance easy (when using the float-type holder) ■ The electrode is a maintenance-friendly tip-detecting polarographic type ■ Easy settings through a dialogue method ■ Built-in self-diagnosis function allows for monitoring the condition of the equipment *For more details, please refer to the PDF document or feel free to contact us.

The "HWML-211/211F" is an MLSS meter (Mixed Liquor Suspended Solids meter) that enhances the functionality and performance of the MLSS meter "HWML-210-200," based on near-infrared light and alternating light emission technology. The shape of the detector's liquid contact part is simple, resulting in less entanglement with impurities and reduced maintenance frequency. By adopting near-infrared light, it is less affected by the color of the solution, and green algae do not adhere to the detection surface. Additionally, the vertical surface detection, which is less affected by bubbles, minimizes the impact of bubbles. 【Features (excerpt)】 ■ Less affected by sludge color due to the use of a special algorithm ■ The light source is alternately emitted, making it less susceptible to external light interference ■ Built-in self-diagnosis function allows for monitoring the device's condition ■ Calibration data input can be selected from zero-span input method, regression automatic calculation method, or piecewise approximation method ■ Various parameters can be modified *For more details, please refer to the PDF document or feel free to contact us.

The "HWUV-222S/311D" is a continuous UV meter (organic pollution monitor) that utilizes the ultraviolet absorbance method. Since it is an optical measurement that does not require chemicals or heating, it can perform continuous measurements without delay, making maintenance of the device easy, and it has a high correlation with COD. The effects of turbidity and contamination of the measurement cell are eliminated, and the measurement cell is automatically cleaned with a reagent regularly, ensuring stable measurements. 【Features (excerpt)】 ■ Product that complies with the Ministry of Land, Infrastructure, Transport and Tourism's standard specifications for automatic ultraviolet absorbance measuring instruments (UV meters) ■ Adopts a single optical path dual-wavelength method, unaffected by changes in the temperature of the light source or over time ■ No reagents required, easy calibration and maintenance ■ Simple batch measurement possible with 1-2L of sample water ■ Sampling type (HWUV-222K) and immersion type (HWUV-311D) can be selected according to application * For more details, please refer to the PDF document or feel free to contact us.

The HWSC-321P is a near-infrared sludge density meter that is inserted into pipelines to measure sludge concentration (SS). It uses a near-infrared light-emitting diode as the light source, which minimizes concerns about light source failure, making it suitable for measuring return sludge concentration and feed sludge concentration. Due to the adoption of a special algorithm, it is less affected by sludge color, and no extra piping such as bypass pipes is required. 【Features (excerpt)】 ■ Less affected by solution color, and green algae do not adhere to the detection surface ■ Almost unaffected by fine bubbles during flow ■ The detector can be detached, making it easy to clean the detection surface and manage accuracy ■ Built-in self-diagnosis function allows for monitoring of the device's condition ■ Selectable from zero-span input method, automatic regression calculation method, and piecewise linear approximation method *For more details, please refer to the PDF document or feel free to contact us.

The "HWTU-211/211N" is a direct immersion type turbidity meter for continuous processes based on near-infrared and alternating light emission technology. By adopting near-infrared light, it is less affected by the color of the solution and is less prone to green algae adhering to the detection surface. The simple shape of the detector's liquid contact part reduces the entanglement of foreign substances, thereby decreasing maintenance frequency. Additionally, the built-in self-diagnosis function allows for monitoring the condition of the equipment. 【Features (excerpt)】 ■ Utilizes a 90° scattering light method, excellent for turbidity measurement ■ Measurement range from a minimum of 0 to 2 degrees to a maximum of 0 to 200 degrees (An optional range of 0 to 1000 degrees is also available) ■ Allows selection between turbidity calibration and SS calibration ■ Complicated zero calibration is easy and accurate without water ■ Data input is simple with a Japanese display interactive method *For more details, please refer to the PDF document or feel free to contact us.
