TB-II G is an exhaust O2 sensor that uses stabilized zirconia ceramic in its detection section. This sensor functions as an O2 meter in combination with a control unit and gas suction accessories. Optimal accessories are provided depending on the target equipment, and the zirconia sensor is protected in multiple layers, making it resistant to attacks from corrosive gases such as HCl and SOx. Its simple structure allows for easy maintenance, and it can measure CO+H2 concentrations during fuel excess (displayed as negative O2%). It is ideal for various combustion exhaust gas applications, including boilers, steel heating furnaces, glass melting furnaces, ceramic firing kilns, and waste incineration plants. For more details, please contact us or refer to the catalog.

The aspirator block is an air-driven sample suction device. It is used in combination with a sampling probe as a sample introduction tube. By screwing the TB-II G sensor into the sensor mounting port and installing it on the short pipe or flange that has been constructed at the measurement location, air is introduced, and the sample gas is suctioned from the tip of the probe. There are two methods for discharging the sample gas: atmospheric release type and return type, which can be selected according to the equipment. It can be installed in a horizontal to vertical orientation. For more details, please contact us or refer to the catalog.

The guide probe is a sampling device that utilizes the sample gas flow. It is installed by screwing the TB-II G sensor into a mounting port, which is set up in areas with gas flow, such as ducts, using a short mounting pipe or flange. The sample gas enters the probe from the sample inlet on the upstream side, is guided along the guide plate to the sensor section, and is discharged through the sample outlet on the downstream side. It can be installed in a horizontal to vertical position. For more details, please contact us or refer to the catalog.

The TB-II F is an O2 sensor that uses stabilized zirconia ceramic in its detection unit. This sensor functions as an O2 meter in combination with a control unit. It accommodates a wide range from ppm O2 levels in clean gas to 100% O2. The zirconia sensor is protected multiple times and has a structure that is resistant to attacks from corrosive gases such as HCl and SOx. It is less affected by sample flow rates and can measure within a flow range of 0.2 to 5 L/min. Additionally, its simple structure makes maintenance easy. For more details, please contact us or refer to the catalog.

Oxygen deficiency accidents continue to occur in clean rooms and research facilities isolated from the outdoors, as well as in environments using inert gases. To prevent such troubles, thorough monitoring of "oxygen concentration" is essential, but are your measures sufficient? It will be too late once the worst-case scenario occurs! The "Air-C Series" from Daiichi Thermal Research is a wall-mounted stationary oxygen monitor. By adopting a zirconia sensor, it enables stable measurements over long periods! It can accurately detect decreases in oxygen concentration, allowing for prompt action. Additionally, it achieves both miniaturization and cost reduction, requiring minimal installation space and keeping introduction costs low. [Features] - The zirconia sensor allows for stable measurements over long periods. (2-year warranty) - Optionally, the detection unit can be installed at a remote location. (Cable lengths of 3m, 5m, 10m) - When the oxygen concentration falls below the set value, an alarm lamp lights up, a buzzer sounds, and contact output is provided. - Smaller than our previous models and more affordable compared to other manufacturers' products. *For more details, please contact us or refer to the catalog.

This document is a list of applications for the "TB Series." Our zirconia-based oxygen analyzers each have their own features by series, but particularly this series is used in a very wide range of applications due to its design, from measuring trace oxygen in high-purity gases to vacuum environments and oxygen measurement in combustion exhaust gases.
