摘要： A probe unit includes a gas sensor having multiple gas introduction bores for introducing a gas into an inside of the gas sensor, and a sensor holder inside of which the gas sensor is held and that is arranged inside of a duct so as to introduce an exhaust gas flowing in the duct into the gas sensor. A calibration gas flow channel is arranged in the sensor holder and has an opening at an inner surface of a side wall, surrounding the gas introduction bores of the gas sensor, of the sensor holder so as to supply a calibration gas to the gas sensor. A guide groove is arranged continuous to the opening of the calibration gas flow channel and arranged on the inner surface of the side wall along an arranging direction of the multiple gas introduction bores to face the multiple gas introduction bores.

摘要： A probe for gas analysis is provided in a pipe through which sample gas flows. The probe includes a tubular member and one or more sample gas inflow portions. The tubular member is disposed to cross a flow of the sample gas, and includes a measurement field to which the sample gas is introduced. The one or more sample gas inflow portions are provided in the tubular member. The sample gas flows around, and flows into the measurement field through the one or more sample gas inflow portions.

摘要： An air-driven shutter device is used in an optical analyzer. The optical analyzer includes a measurement field to which a sample is supplied, a light-emitting unit measurement field for emitting measuring light to the sample, a light-receptive unit for receiving the measuring light that has passed through the sample, and a purge air supplying unit for supplying purge air. The air-driven shutter device includes a shutter and a shutter opening and closing mechanism. The shutter is disposed between the light-emitting unit and/or the light-receptive unit and the measurement field. The shutter opening and closing mechanism keeps the shutter open with pressure of the gas supplied from the purge air supplying unit, and closes the shutter when the pressure of the gas supplied from the purge air supplying unit becomes lower than a predetermined level.
