We will exhibit at INCHEM TOKYO 2023.

This is a collection of case studies for Instran water quality meters.

A summary of case studies on the measurement and control of ammonia, aluminum, and manganese in drinking water treatment facilities has been compiled.

• Other measurement, recording and measuring instruments

Fluorine concentration can be measured with a wide range and high precision from a minimum of 0 to 0.5 ppm to a maximum of 0 to 100 ppm!

We adopt the SKA method to calculate concentration based on the difference in concentration between a standard solution of known concentration and the sample. By comparing the potential differences, we can minimize the impact of the measurement environment on the results. During measurement, reagents are used to adjust the pH. This removes interference from ions other than fluoride, enabling high-precision measurement of fluoride concentration.

• Other measurement, recording and measuring instruments

It is possible to measure chlorine ion concentration with a wide range and high precision from a minimum of 0 to 5 ppm to a maximum of 0 to 500 ppm!

The SKA method is employed to calculate concentration based on the difference in concentrations between a standard solution of known concentration and the sample. By comparing the potential differences, the influence of the measurement environment on the results can be minimized. There are several interfering substances in the measurement of chloride ions, but this method allows for their easy removal.

• Other measurement, recording and measuring instruments

It is possible to measure the concentration of dissolved ammonia, such as that found in seawater, for a wide range of applications.

The Spanish-made INSTRAN ammonia meter is designed to accommodate all types of samples, from drinking water to wastewater and seawater. It incorporates laboratory measurement techniques into an online analysis device, performing automatic calibration and automatic cleaning for each analysis, enabling high-precision measurements. The syringe volume control method ensures that the syringe does not come into contact with the sample or reagents, extending the lifespan of the syringe. It requires minimal maintenance, consumes less reagents, and maintains high precision.

• Water quality testing

Minimum measurement range 0~100 ppb! Capable of measuring low concentrations of boron!

This is an online boron concentration meter capable of measuring low concentrations of boron in the range of 0 to 100 ppb. After performing a blank measurement to correct for the effects of temperature and turbidity on the measurement, actual measurements are conducted. This minimizes the impact of environmental factors on the measurements, allowing for high-precision measurement of boron concentration.

• Other measurement, recording and measuring instruments

It is possible to measure boron concentrations of up to 500 ppm with high precision!

By using a syringe that allows for injection volume adjustments in increments of 0.0015 ml, high-precision measurement of boron concentration can be achieved through the injection of titrant. The preparation of reagents is easy and inexpensive, allowing for low-cost operation. Additionally, by adjusting the concentration of the reagents, it is possible to change the measurement range.

• Other measurement, recording and measuring instruments

Specialized in online water quality analysis, it can measure various substances such as boron and ammonium using two types of measurement methods: colorimetry and ISE.

To ensure that the water used by our customers is always managed correctly, Instran's online analysis equipment can measure many water quality parameters, including boron and ammonium, with high precision. By using two types of measurement methods, colorimetry and ISE, depending on the measurement target, we can accommodate a variety of water quality parameters. Additionally, it is equipped with automatic cleaning and calibration functions, resulting in less frequent maintenance. The amount of reagents used in a single measurement is minimal, allowing for low-cost maintenance of high precision.

• Other measurement, recording and measuring instruments

This is a collection of case studies on ammonia meters.

We have compiled the results of the introduction of ammonia concentration measurement in saltwater.

Nitto Kohki will hold the "2024 Attack Fair in Ichihara" at the "Yume Hall" for two days from December 11 (Wednesday) to December 12 (Thursday), 2024. The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful souvenirs for visitors and many fun activities prepared. We look forward to welcoming everyone!

Nitto Kohki will hold the "2025 Attack Fair in Kurume" at the "Local Production Kurume General Exhibition Hall" for two days from February 13 (Thursday) to February 14 (Friday), 2025. The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful commemorative gifts for visitors and many fun activities prepared. We look forward to welcoming everyone!

**Seminar Overview** The construction industry faces many challenges, including a shortage of personnel, regulations on maximum working hours, and the need for efficiency improvements. Additionally, the transmission of skills due to an aging workforce has become a significant issue, with a high turnover rate among younger employees who are supposed to carry on these skills. In this seminar, we will discuss the causes of turnover based on case studies and explain key points on how to reduce turnover rates by advancing IT integration.

**Seminar Overview** "Generative AI," which is gaining attention as a method for improving business efficiency and utilizing internal digital transformation (DX), can be influenced by the literacy of the employees using it, potentially increasing the burden of work instead. In this seminar, we will discuss the current challenges of generative AI while providing examples of how it can be used to enhance business efficiency. We will also explain how to utilize generative AI in a way that achieves efficiency without being dependent on the user's skills. We hope this will serve as a reference for considering the use of generative AI.

**Seminar Overview** The reality that young members leave their jobs due to miscommunication with their superiors occurs in every industry. This is also true in the construction industry. The long-standing issues of labor shortages, regulations on working hours, and the challenges of passing on skills due to an aging workforce are significant problems. However, the misalignment in communication with young employees, who are supposed to be receiving this knowledge, may actually worsen the situation. In this seminar, we will discuss the causes of communication gaps as seen through case studies, and talk about methods for skill transfer, knowledge accumulation, and smooth internal communication using IT tools.
