ハンナインスツルメンツ・ジャパン Product Lineup

In Japanese plating factories (such as nickel, zinc, and chrome), compliance with wastewater standards based on the Water Pollution Prevention Act is required, and in recent years, reducing water usage and wastewater load has become important from both environmental and cost perspectives. Against this backdrop, counterflow multi-stage rinsing (counterflow cleaning/multi-stage rinsing) has been widely adopted as it can achieve both cleaning efficiency and water conservation. Counterflow multi-stage rinsing involves connecting multiple rinse tanks in series, where new water introduced into the last tank flows sequentially to the preceding stages. This mechanism ensures that parts are cleaned with the most purified water at the end of the process. As a result, it can significantly reduce water usage and wastewater volume while maintaining equivalent cleaning quality compared to traditional single rinsing or continuous spraying methods. *For more detailed information, please refer to the related links.

Additionally, it supports dual channels. 【Features】 ■ Modbus/RS485 compatible ■ Up to 5 relay contacts ■ Fluorescent DO sensor *For more details, please download the PDF or feel free to contact us.

• Water quality testing

The fluorescent type is equipped with a smart cap, making maintenance easy! There is no need for warm-up, so measurements can be taken immediately after turning on the power. Since it does not consume oxygen during measurement, it can measure up to 50 mg/L even without flow rate. It can manually save up to 4000 data points, and transfer to USB memory or PC is also possible. (Displayed in CSV format on PC) It enables quick and stable measurements in various environments.

The Marine Master HI 97115 is a portable spectrophotometer that combines accuracy and ease of use. It achieves high precision and reliability through an advanced optical system, and is designed to be compact. It is truly a design that condenses technology. For aquaculture and aquariums, it can measure ammonia, nitrite nitrogen, nitrate, pH, alkalinity, calcium, magnesium, and phosphate all with this one device (reagents are used for each measurement item). - Advanced optical system featuring a beam splitter - Validation of the device using a NIST-traceable validator - Navigation function for measurement procedures - Automatic data storage function for up to 200 data points - Ability to assign locations to stored measurement data - Waterproof casing with an IP67 rating (the glass cell insertion part is also waterproof) - Backlight function for better visibility - Battery level (%) is always displayed on the screen - Time setting available (year, month, day, and time) Rental use is also available!

• Analytical Equipment and Devices

It is an excellent device that allows simultaneous measurement by connecting a pH/ORP sensor, EC sensor, and DO sensor to a single electrode. It is a robust waterproof type suitable for outdoor use, and measurements are taken by submerging the electrode. The measurement values can be continuously stored in the main unit, and data management can be performed by connecting it to a PC. This single unit can measure pH/ORP/EC/TDS/resistivity/salinity/specific gravity of seawater/DO/atmospheric pressure/°C.

1. Automatic checks for each stage before measurement Calculates and automatically adjusts for excess residual moisture and surrounding humidity. Maintains a state that allows for accurate measurements at all times. Measurement begins after calculating the moisture values for each stage. 2. Endpoint detection method In addition to the conventional mV endpoint method, there is also a unique relative drift endpoint function. 3. Easy to see and use The visibility has improved with a 5.7-inch backlit color display, making the titration curve even easier to read compared to previous models. The operation buttons are also part of the display and are sealed, making them resistant to dirt and easy to clean. 4. Sealed solvent system Minimizes exposure to surrounding humidity, saving on titrant consumption and time. Additionally, it automatically adjusts titration calculations considering the influence of surrounding humidity entering the titration cell. This allows for the correction of water not present in the actual sample, resulting in more accurate results.
