Due to the same reaction conditions as the JIS method, a high correlation can be obtained. The amount of reagent used is significantly reduced.

It supports a wide measurement range of up to 15,000 mg/L. All reagents necessary for measurement are pre-adjusted; simply place the sample in the vial containing the reagent, heat it for decomposition, and then read the results with the measuring instrument.

I will explain the long-term test regarding the measurement methods for COD and nitrate without the use of reagents, conducted at the Paisenberg wastewater treatment plant. The test began in early November 2015 and was carried out to evaluate the effects of seasonal changes.

Chemical Oxygen Demand (COD) It is the amount of oxidizing agent consumed when organic matter in water is decomposed by an oxidizing agent, converted into an equivalent amount of oxygen. It indicates the degree of organic pollution in lakes and marine areas (unit: mg/L).

● No calibration required, reagent-free measurement ● Ultra-low maintenance design with air cleaning + ultrasonic cleaning method

Customers measuring COD using the JIS method. By introducing a simple COD meter, you can expect a reduction in measurement time and an improvement in work efficiency! For example, simple COD meters using electric titration methods or spectrophotometry allow for rapid and accurate measurements. This enables immediate response on-site and enhances operational efficiency. Let's first take a look at what benefits there are!

The IQ Sensor Net system helps collect the necessary data for monitoring and controlling processes by freely combining 21 types of sensors. It supports small-scale operations with 2 sensors up to large-scale processing processes with a maximum of 20 sensors, providing optimal water quality management tailored to users. It also supports remote monitoring, allowing data to be viewed from anywhere using a smartphone, tablet, or computer as long as there is an internet connection. This enables operation from outside the facility when urgent on-site response is needed. Types of sensors: DO (marine water compatible model available), pH/ORP (marine water compatible model available), conductivity (marine water compatible model available), turbidity (marine water compatible model available), color, SS (marine water compatible model available), MLSS, ammonia, nitrate, nitrite, organic matter, sludge interface.
