                                                                                                                                                                      目測法,重量法,顯微鏡計數法,壓差計數法,自動顆粒計數法(光散熱法和遮光法,用于油液檢測的是遮光法);

                                                                                                                                                                      利用遮光法,有離線(取樣、間斷)分析和在線監測兩類設備。

                                                                                                                                                                      遮光法油液顆粒污染度檢測儀采用ISO4402/ISO11171規定的遮光法(Light Extinction)(又稱為光阻法或消光法)原理進行油液污染度檢測,具有檢測速度快,抗干擾性強,精度高,重復性好等優點。
