1.Product Overview:
This product adopts spectrophotometric measurement. Under certain acidity conditions, the ferrous ions in the sample react with the indicator to generate a red complex. The analyzer detects the color change and converts it into iron values. The amount of colored complex generated is proportional to the iron content.
2.Product Principle:
2.1 Instrument Features:
Ø Uses photometric medicine addition, enables precise metering;
Ø Cold light source spectral measurement, extends light source life;
Ø Automatically adjusts light source intensity, maintains measurement accuracy after light source decay;
Ø Automatically controls reaction temperature, constant temperature measurement and calibration;
Ø Large capacity memory, saves 5 years of measurement data;
Ø 7-inch touch color LCD, more intuitive operation and display;
Ø Single channel of isolated current output, configurable to any channel, any range or PID;
Ø Single channel of relay output, can be configured for over-limit alarm, no-sample alarm or system failure alarm;
Ø RS485 interface, enables remote data monitoring;
Ø Query curves and measurement alarms for any time period.
