・ Low concentration oxygen gas can be produced from a nitrogen supply source such as a factory nitrogen line. (No standard oxygen gas cylinder required)

・ The oxygen gas concentration can be set arbitrarily within the range of 1-1000ppm. (In 1ppm increments)

・ Multi-point automatic calibration is possible by connecting to our oxygen analyzer.

・ Since the device body is portable, calibration on site is easy.

・ It can be used for all oxygen analyzers with ppmO2 concentration, mainly for maintenance applications such as reflow furnaces and diffusion furnaces.
