英文摘要	The large high altitude air shower observatory (lhaaso) is being constructed at 4400 m a.s.l. in daocheng, sichuan province, aiming to reveal the secrets of cosmic rays origin. and it has the largest surface muon detector array in the world. due to the needs of calibration and construction of muon detector, we developed a water optical attenuation measurement device using an 8 m long water tank. the results are presented for filtered water at wavelength of 405 nm, which proves this apparatus can reach an accuracy of about 20% at 100 m. this apparatus has not only a high precision measurement of water attenuation length up to 100 m but is also very convenient to be used, which is crucial for water optical properties study during lhaaso detector construction.
