DO3控制器能提供實(shí)時(shí)DO3濃度值測(cè)量，外部報(bào)警及控制輸出和隔離式模擬量輸出。控制器有1/4DIN鋁合外殼盤(pán)面安裝形式、適于惡劣環(huán)境使用的NEMA4X玻璃外殼。在鬼斧神控制器前面板上有5個(gè)軟鍵可進(jìn)行功能設(shè)置允許用戶(hù)讀取諸如水溫、報(bào)警點(diǎn)、輸出模擬量等參數(shù)，并且可通過(guò)設(shè)定密碼來(lái)阻止誤操作。DO3測(cè)定儀可設(shè)定高/低量程，在低量程0-1.00PPM范圍內(nèi)，分辨率0.001PPM；高量程0-2.00PPM范圍內(nèi)，分辨率0.01PPM。對(duì)于一些特殊應(yīng)用 場(chǎng)合測(cè)量范圍可到0-200PPM。隔離式4-20mA輸出端口可與外部數(shù)字記錄儀相連，輸出信號(hào)可以在其量程范圍內(nèi)進(jìn)行選擇，也可以通過(guò)采用一個(gè)并聯(lián)電阻輸出電壓情況下改變成0-20mA模擬輸出。

*精度是基于比較DO3和同時(shí)測(cè)量的參比測(cè)量表上的讀數(shù)；溶解臭氧是非常不穩(wěn)定，要獲得的精度，請(qǐng)遵循手冊(cè)。干擾取決于干擾氣體的濃度和種類(lèi)。
DO3 by Eco Sensors (a division of KWJ Engineering) is a rapid, simple to use device for checking the ozone concentration in water and is calibrated in mg/L (same as parts-per-million by volume in water).  This small, battery-operated detector offers an inexpensive alternative to more costly inline monitors and requires no disposable reagents.  DO3 is a practical, versatile detector for applications where the user needs to confirm that a system is ozonating the water, but does not need the “accuracy” and high cost of complicated analytical, inline dissolved ozone meters.
