Mi180可測(cè)量6個(gè)參數(shù)：pH, ORP, EC, TDS，NaCl百分比，多種溫度量程測(cè)試
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(cè)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(cè)量時(shí)具有自動(dòng)量程修正特點(diǎn)，可為測(cè)試樣品自動(dòng)調(diào)節(jié)分辨率。所有測(cè)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(cè)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(cè)量更加精確。為測(cè)
