For measuring temperature, humidity, atmospheric pressure, and oxygen concentration. Maintenance-free due to optical design.
This is a sensor that adds oxygen concentration measurement functionality to the standard sensor "M4557THTI-101H," which measures temperature, humidity, and atmospheric pressure. Generally used galvanic battery-type oxygen concentration meters suffer from aging degradation, leading to issues with accuracy and the need for regular replacement. In contrast, this sensor is an optical non-consumable type, making it maintenance-free. Additionally, it has little sensitivity to most other gases, allowing for more accurate measurements. It is lightweight and compact, making it suitable for various installation locations. By connecting it to a PC or similar device via a USB Type C cable, communication and power supply are facilitated. Furthermore, for measurements taken more than 5 meters away, where communication via USB cable may be difficult, serial communication via RS-232C is also possible.
