AZ8403 Dissolved Oxygen Meter for Freshwater Aquaculture - High Precision Water Quality Tester with LCD Display | Ideal for Fish Tanks, Hydroponics & Pond Monitoring

The portable DO meter can measure the value of Dissolved Oxygen with unit of % or ppm or mg/l in liquid, which had been widely operation in the Water Quality Testing applications. It has the big LCD which can display the D.O. (Dissolved Oxygen) value and the temperature.The salinity and barometric pressure could affect the DO measuring accuracy, and that could be adjustable in 8403 Digital DO Device, which could help user to get the accurate Dissolved Oxygen value.Model AZ8403DO Measuring Range:0~199.9 (in %)DO Accuracy:±1.5% F.S (in %)DO Resolution:0.1% (in %)DO Measuring Range:0~19.99 (in ppm or mg/l)DO Accuracy:±1.5% F.S (in ppm or mg/l)DO Resolution:0.01 (in ppm or mg/l)Temperature Measuring Range:0~50.0℃Temperature Accuracy:±0.3℃Temperature Resolution:0.1℃Manual Compensation:IncludedSalinity Adjustable Range:0.0~50.0 pptSalinity Resolution:0.1 pptBarometric Pressure Adjustable Range:500~1499 mmHg/66.6~199.9 KpaBarometric Pressure Resolution:1 mmHg/0.1 KpaCoefficient of membrane:AdjustableMemory:99 PointsIrDA Port:IncludedReal Time/Recall:IncludedLCD Size:44(L)*26 (W) mmOperating Temperature:0~50℃Operating RH%:Humidity ＜80%Storage Temperature:0~60℃Storage RH%:Humidity ＜90%Sensor Life Time:>6 months (with good maintenance)Meter Size:175(L) * 70(W) * 33(H) mmWeight:~150gBattery:AAA *4 PCS(Not Included)Standard Package:Meter, Dissolve Oxygen (D.O.)
