Claims (1)
測定装置において、 上記風胴内に挿入する吸引ノズルを通して試料
ガスが吸引される測定用ダクトを備え、この測定
用ダクトにおける試料ガスの直線的な流れが形成
される部分の両端に、試料ガスの流れの方向に沿
つて測定用ビームを投射して試料ガス内を透過し
た光の減衰量から実時間で排気煙濃度の測定を行
う光透過式ダクト濃度計を配設したことを特徴と
する自動車排気煙濃度測定装置。[Scope of Claim for Utility Model Registration] A measuring device for measuring the concentration of automobile exhaust smoke using a diluted wind cylinder, comprising a measuring duct through which a sample gas is sucked through a suction nozzle inserted into the wind cylinder; A measurement beam is projected along the flow direction of the sample gas at both ends of the part of the duct where the sample gas flows in a straight line, and exhaust smoke is measured in real time based on the attenuation of light transmitted through the sample gas. An automobile exhaust smoke concentration measuring device characterized by being equipped with a light transmission type duct concentration meter for measuring concentration.
