選(xuan)擇氣密(mi)(mi)性檢(jian)測(ce)設備(bei)(bei)的(de)(de)幾點(dian)依據(ju)：進口的(de)(de)氣密(mi)(mi)性檢(jian)測(ce)設備(bei)(bei)與國產(chan)(chan)的(de)(de)相比，充電器(qi)密(mi)(mi)封檢(jian)測(ce)，質量不錯，但是(shi)價格高(gao)，密(mi)(mi)封檢(jian)測(ce)，是(shi)國產(chan)(chan)的(de)(de)好幾倍。國產(chan)(chan)氣密(mi)(mi)性檢(jian)測(ce)設備(bei)(bei)魚龍混雜，高(gao)l端的(de)(de)國產(chan)(chan)業(ye)與進口相當，具體(ti)的(de)(de)要根據(ju)檢(jian)測(ce)產(chan)(chan)品、檢(jian)測(ce)要求及(ji)公(gong)司預算選(xuan)擇。

精度測(ce)試。精度的第(di)l一(yi)層含(han)義是(shi)準確性，比(bi)如射(she)(she)擊(ji)(ji)運動(dong)能直(zhi)擊(ji)(ji)靶(ba)(ba)心(xin)。第(di)二層含(han)義是(shi)允(yun)許的偏差(cha)范圍(wei)。靶(ba)(ba)心(xin)面積大(da)小，電池密封檢測(ce)，同(tong)樣(yang)是(shi)擊(ji)(ji)中靶(ba)(ba)心(xin)，射(she)(she)中小面積靶(ba)(ba)心(xin)的精度就高。

多次重(zhong)復(fu)性測(ce)試。這是為重(zhong)要的(de)(de)一個指標(biao)，可以反映儀器的(de)(de)綜合性能，暫(zan)不深(shen)入探(tan)討(tao)。所謂重(zhong)復(fu)性指在相(xiang)同(tong)的(de)(de)環境溫度下(xia)，在相(xiang)同(tong)的(de)(de)測(ce)試壓力下(xia)，儀器所顯(xian)示(shi)數據的(de)(de)一致性。

廠家(jia)實(shi)力(li)。可以(yi)從銷售(shou)人員素質(zhi)、市場份額(e)、客戶實(shi)力(li)等(deng)方面(mian)綜(zong)合判(pan)定商家(jia)的整(zheng)體實(shi)力(li)。
