Optical Dissolved Carbon Dioxide Sensor CO2NTROL RS485
Dissolved carbon dioxide (DCO₂) sensor
Technology for solving problems: MIR optical sensor
The optical dissolved carbon dioxide (DCO₂) sensor for processes uses an MIR optical sensor to directly measure dissolved carbon dioxide (CO₂) by combining DCO₂ with MIR wavelengths (mid-infrared) and a CO₂ diffusion membrane. This allows for inline measurements with unprecedented high reliability and good reproducibility. The sensor itself is calibrated before shipment, so it can be used immediately after sterilization. Additionally, there are no replacement parts, allowing for use with two-point calibration and adjustment using carbon dioxide-free gas and 100% carbon dioxide gas. The lifespan is approximately up to 3 years. When sensitivity degrades, the sensor body will need to be replaced.

basic information
■Main Specifications - Operating temperature range: -10 to 140°C - Carbon dioxide measurement range: -10 to 60°C If the temperature exceeds 60°C, the output will hold the last measurement value prior to that. When the temperature returns to the CO2 measurement range, CO2 measurement will automatically resume. - Process pressure: -0.1 to 1.19 MPa - Measurement range and resolution: 5 to 1000 mbar, 0.5 to 100%-vol., 7.5 to 1500 mg/L (liquid phase, atmospheric pressure 101.3 kPa, 25°C reference) - Accuracy: ±5 mbar (5 to 100 mbar), ±5% (>100 mbar) - Response time (gas phase): Approximately 200 seconds for response from 0 to 95%-vol., approximately 220 seconds for response from 100%-vol. to 5%-vol. - Measurement limit: Lower limit of the range - Measurement error: Variation range per week - Electrical connection standard: VP8 - Operating power supply voltage: 13 to 27 VDC - Digital interface: 2-wire RS-485 Modbus RTU protocol - Cleaning and sterilization performance: Compatible with SIP, autoclave, CIP - Measurement principle: Optical non-dispersive infrared method - Shipping condition: Calibrated. Ready for measurement upon installation - Protection rating: IP68 - Storage temperature: 0 to 45°C

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.
