PSZ129自動(dòng)酸值測(cè)定儀

PSZ129自動(dòng)酸值測(cè)定儀，根據(jù)市場(chǎng)的迫切要求，*按照GB/T7599-87標(biāo)準(zhǔn)設(shè)計(jì)研發(fā)，為國(guó)內(nèi)*。是可準(zhǔn)確檢測(cè)變壓器油酸值的全自動(dòng)測(cè)定儀器。該儀器在提高工作效率和測(cè)試精度的同時(shí)，減少操作人員接觸試樣和試劑，zui大限度的保障其人身安全。
無需人工稱量，只需將試樣放置在試樣杯內(nèi)，儀器便自動(dòng)進(jìn)行進(jìn)樣、加熱回流、測(cè)定、排出廢液、顯示打印結(jié)果等操作。
測(cè)定中儀器自動(dòng)扣除乙醇本底值和指示劑本底值，結(jié)果更準(zhǔn)確。一次啟動(dòng)可測(cè)定1～8個(gè)試樣，使用方便，效率高。儀器備有標(biāo)定儀器用標(biāo)準(zhǔn)酸和標(biāo)定程序，用戶可隨時(shí)對(duì)儀器和中和液進(jìn)行標(biāo)定，克服了中和液使用中濃度發(fā)生變化的缺陷，提高了測(cè)試結(jié)果的可靠性。
