Mi180可測量6個參數(shù)：pH, ORP, EC, TDS，NaCl百分比，多種溫度量程測試
PH可在7個記憶點人選三個自動校準(zhǔn)，甚至在測試兩種量程差別很大的試樣時也能提供精準(zhǔn)的校準(zhǔn)曲線。在EC和TDS測量時具有自動量程修正特點，可為測試樣品自動調(diào)節(jié)分辨率。測量可以設(shè)定在20度和25度，使用者可選擇自動溫度補償。在測量電導(dǎo)率時可以關(guān)閉自動溫度補償。屏幕上的穩(wěn)定性指示器可使測量更加。為測量電導(dǎo)率提供4環(huán)電導(dǎo)電。GLP特點可以記錄，儲存數(shù)據(jù)并通過RE232或U傳到電腦中
