The CTD series is a compact, simple, and cost-effective multi-parameter water quality analyzer for conductivity, water depth, and water temperature. It can be easily deployed in groundwater and surface water to monitor multiple parameters such as conductivity, salinity, TDS, resistivity, density, water level, pressure, and temperature. With its robust IP68 underwater housing, it is ideal for various applications including aquifer characterization, construction and mining, drilling and wells, coastal estuaries and wetlands, lakes and reservoirs.

It is possible to continuously measure BOD (Biochemical Oxygen Demand) without using reagents. 【Measurement Method】 This analytical device consists of a light source, sample cell, and light detector. The light incident on the sample is absorbed by components in the water, and by measuring the transmitted light with the detector, a BOD equivalent value based on the absorbance in the sample is calculated. A long-life LED is used as the light source, achieving high measurement accuracy through a 180° optical method compliant with international standards. Additionally, an automatic wiper mechanism removes bubbles and dirt adhering to the optical window, maintaining a clean state at all times, which balances precision maintenance and reduced maintenance load. 【Features】 ■ Continuous and real-time measurement of BOD without reagents ■ All-in-one compact housing with built-in transmitter and sensor ■ Equipped with an automatic wiper to keep the optical window clean and maintain stable measurements ■ Equipped with RS485 digital communication ■ Low power consumption design, ideal for outdoor and long-term operation

It is possible to continuously and in real-time measure COD (Chemical Oxygen Demand) without the use of reagents. 【Measurement Method】 This analytical device consists of a UV 254nm light source, a sample cell, and a light detector. The light incident on the sample is absorbed by components in the water, and by measuring the transmitted light with the detector, the COD equivalent value based on the absorbance in the sample is calculated. The light source uses a long-life LED and achieves high measurement accuracy through a 180° optical system compliant with international standards. Additionally, the automatic wiper mechanism removes bubbles and dirt that adhere to the optical window, maintaining a clean state at all times, which ensures precision and reduces maintenance load. 【Features】 ■ Continuous and real-time measurement of COD without reagents ■ All-in-one compact housing with built-in transmitter and sensor ■ Equipped with an automatic wiper to keep the optical window clean and maintain stable measurements ■ Equipped with RS485 digital communication ■ Low power consumption design, ideal for outdoor and long-term operation

It is possible to continuously and real-time measure sulfide (S²⁻) without using reagents. 【Measurement Method】 Continuous measurement of sulfide is performed using an ion-selective electrode with a specific membrane that is selective for sulfide ions. This membrane creates charge separation between the electrode surrounded by water and the internal filling solution. The charge is measured as voltage and changes in response to concentration variations in the water adjacent to the water membrane. Compared to conventional colorimetric methods, it has many advantages, including faster response time, greater accuracy, ease of operation, and no need for reagents. 【Features】 ■ Continuous and real-time measurement of sulfide (S²⁻) without reagents ■ All-in-one compact housing with built-in transmitter and sensor ■ Equipped with an automatic wiper to keep the optical window clean and maintain stable measurements ■ Equipped with RS485 digital communication ■ Low power consumption design, ideal for outdoor and long-term operation

It is possible to continuously and real-time measure turbidity. 【Measurement Method】 This is a turbidity analyzer using a scattered light method with near-infrared light (880 nm). The turbidity analyzer consists of a light source, sample cell, and light detector. The incident light is scattered by particles within the sample, and the scattered light is measured by the detector. The amount of scattering varies depending on the quantity of substances in the sample, the wavelength of the light used, and the size and composition of the suspended particles. This analyzer features a long-life LED (880 nm) and complies with the 90° scattered light method according to DIN ISO 7027 or EPA Method 180.1. The automated machine wiper keeps the surface clean to maximize accuracy and minimize maintenance needs by removing bubbles from the optical window. 【Features】 ■ Continuous and real-time turbidity measurement without reagents ■ All-in-one compact housing with built-in transmitter and sensor ■ Equipped with an automatic wiper to keep the optical window clean and maintain stable measurements ■ Includes RS485 digital communication ■ Low power consumption design, ideal for outdoor and long-term operation

It is possible to continuously and in real-time measure ultra-low concentration oil components (PAHs) without using reagents. 【Measurement Targets】 PAHs (Naphthalene, Acenaphthylene, Acenaphthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Chrysene, Benzo[a]anthracene, Dibenzo[a,h]anthracene, Indeno[1,2,3-cd]pyrene, Benzo[ghi]perylene) 【Measurement Principle】 This analyzer is based on fluorescence optical technology. A fluorometer emits light at the wavelength necessary to excite the target substance, selectively transmitting only the fluorescence emitted from the target substance at specific wavelengths, and measuring the intensity of that light. The measured fluorescence intensity is proportional to the concentration of the target substance. 【Features】 ■ Continuous and real-time measurement of ultra-low concentration oil components (PAHs) without reagents ■ All-in-one compact housing with built-in transmitter and sensor ■ Equipped with an automatic wiper to keep the optical window clean at all times, maintaining stable measurements ■ Features RS485 digital communication ■ Low power consumption design, ideal for outdoor and long-term operation
