MI180實(shí)驗(yàn)室pH/ORP測定儀
MI180多參數(shù)水質(zhì)測定儀主要特點(diǎn):
PH可在7個(gè)記憶點(diǎn)人選三個(gè)自動(dòng)校準(zhǔn),甚至在測試兩種量程差別很大的試樣時(shí)也能提供精準(zhǔn)的校準(zhǔn)曲線。在EC 和 TDS測量時(shí)具有自動(dòng)量程修正特點(diǎn),可為測試樣品自動(dòng)調(diào)節(jié)分辨率。所有測量可以設(shè)定在20度和25度,使用者可選擇自動(dòng)溫度補(bǔ)償。在測量電導(dǎo)率時(shí)可以關(guān)閉自動(dòng)溫度補(bǔ)償。屏幕上的穩(wěn)定性指示器可使測量更加精確。為測量電導(dǎo)率提供4環(huán)電導(dǎo)電極。GLP特點(diǎn)可以記錄,儲(chǔ)存所有數(shù)據(jù)并通過RE232或USB傳到電腦中。
