Test Gas Generation Systems TU Series


Test gas generation systems in the TU Series, which include a test gas generation system for evaluating the performance of various kinds of gas sensors as well as systems for generating simulated gases for evaluating catalysts, are tailored to customers’ intended uses. In the biotechnology field, the products we offer are applied as atmosphere gas supply systems inside fermenters.
Systems we propose include those that use multiple mass flow controllers to mobilize functions (e.g., to generate gases of any concentration, to add moisture, to control supplied gas pressure, and to heat gases), thereby allowing for comprehensive control via a PC or PLC.


  1. Test gases can be generated to meet all purposes through simple operation.

    • The large touch panel makes it easy to generate gases to evaluate the performance of various types of advanced sensors.
    • Accurate addition of moisture and humidity control of test gases are enabled by mass flow controllers that perform micro-flow control of fluid and built-in vaporizers.
    • A single unit can perform sensor evaluation thanks to the special heat exchanger and evaluation chamber for each type of sensor, both of which are built into the system.
    • Advanced test gas generation involving changes in concentration of the generated gas over time, the flow rate, and so forth is enabled through the PLC in the control unit.
    • A safety function can be integrated to detect abnormal operations by mounting a temperature sensor, gas leakage sensor, or the like.

  2. Evaluation systems can be tailored to the intended use based on flow control technology.

    • Evaluation systems for combustors for city gas or propane gas
    • Atmospheric gas control systems
    • Evaluation systems for chemical catalysts, etc.
