Dissolved Oxygen Sensor | Autoclave Compatible Optical Dissolved Oxygen Sensor
Autoclave-compatible optical dissolved oxygen sensor
It is compatible with a wide range of industrial processes that have been difficult to measure until now, starting with biopharma.
The VisiFerm DO ECS optical dissolved oxygen sensor, compatible with autoclaves, continuously monitors the condition of the fluorescent membrane through its built-in degradation monitoring function. Since there is no self-consumption of oxygen by the sensor, it can accurately measure dissolved oxygen in low concentrations or in stagnant liquids. The fluorescent membrane can be easily replaced with a cap-type design. In addition to silicone, a Teflon version of the fluorescent membrane is also available. Sterilization compatible: ■ 130°C steam sterilization ■ Fixed cleaning ■ Autoclave

basic information
■Main Features - Using LED light and a phosphor that absorbs and emits light, the principle of light emitted by the phosphor being absorbed by oxygen is utilized to measure oxygen concentration in the range of 4 ppb to 25 ppm. - The phosphor adopts a cap design, making replacement simple and reliable. - Calibration can be performed at the appropriate time by monitoring cap degradation. The process takes about 20 minutes to complete. - It does not have an electrolyte like conventional Clark cells. - There is no influence from flow rate or pressure during measurement. Therefore, there is no instability in measurement values due to stirring, allowing for the measurement of dissolved oxygen conditions at installation locations such as the bottom of tanks. - There is no self-consumption of oxygen by the sensor, allowing for accurate measurement of dissolved oxygen in low concentrations or stagnant liquids. - There are no leaks since no electrolyte is used. - Calibration data is stored in the sensor body, allowing for pre-calibration in a stable environment. - Sensor lengths can be selected from 120 mm, 160 mm, 225 mm, 325 mm, and 425 mm.

Company information
T and C Technical has been engaged in the sale of water quality measurement instruments (such as conductivity and resistivity meters) since its establishment in 1988, and has been providing service operations to guarantee their quality for over a quarter of a century. At the beginning of our business, we focused on the quality of ultra-pure water, which is essential for semiconductor manufacturing, and established a method for our representatives to visit customers on-site to perform maintenance, inspection, and calibration of water quality measurement instruments, becoming the first in Japan to do so. In 1993, we began the development and sale of Total Organic Carbon (TOC) analyzers, which are important indicators for ensuring the quality of ultra-pure water. Since then, our TOC analyzers have been utilized by customers in various industries, including semiconductors, pharmaceuticals, food, and beverages. In recent years, we have been engaged in the sale and maintenance inspection of various measurement instruments related to our specialty area of "water," and we aim to contribute to labor-saving and cost reduction in our customers' equipment operations through these efforts. Additionally, we strive to maintain and improve our advanced calibration techniques, ensuring that we provide even greater peace of mind through the maintenance, inspection, and calibration services of the products purchased by our customers.
