OX400 Low Concentration Zirconia Oxygen Analyzer
Brand: Yokogawa Electric Corporation
The OX400 is a highly accurate and reliable low-concentration zirconia oxygen analyzer that is capable of measuring a wide range of concentrations, from 0 to 10 ppm up to 0 to 100% volume Oxygen.
This is the latest oxygen analyzer from Yokogawa, and its development was based on the company’s long experience and strong track record with this technology.
A proprietary new thin-film deposition technology was used in the zirconia sensor that creates a molecular bond between the zirconia element and the platinum layer.
This prevents separation, enables a reduction in sensor size and ensures a high-speed response and long life.
The OX400 can be used to control and monitor various semiconductor applications, and to control environment, air leakage into inert gas, and other processes.
Features- Long life and high-speed response
- Thanks to the use of Yokogawa’s proprietary new thin-film deposition technology, the sensor has three times the lifespan of those used in our earlier products.
- A cylindrical sensor design facilitates the replacement of measurement gases, thereby helping to assure a high-speed response.
- High performance and high reliability
- Superior repeatability and linearity even at low oxygen concentrations.
- Either pump or aspirator sampling can be selected, depending on the application.
- CE, CSA, etc. certification.
- Built-in functions and a variety of self-diagnosis functions
- Comes with multi selector, auto range, partial range, and pump on/off functions.
- A variety of self-diagnosis functions are provided that detect malfunctions such as heater temperature error, temperature sensor burnout, and sensor resistance value error.
- Superior maintainability
- The sensor can be replaced on-site.
- Compact and lightweight for easy installation.
