Product Description

Description:

Residual chlorine/total chlorine online analyzer, establishes a zero reference point by measuring the blank absorbance, and compensates the color and turbidity of the sample before measuring chlorine; then, the indicator solution and buffer solution are added to the sample, and the sample is color-developed by the magnetic stirrer; then, the colorimeter measures the absorbance through the sample, and the obtained absorbance is compared with the reference standard to obtain the measurement result. The analysis cycle only takes about 2.5 minutes.

Features:

  • DPD colorimetric measurement, reliable

  • Automatic diagnosis and automatic calibration

  • Low reagent consumption, simple replacement

  • Automatic and manual measurement modes

  • Analysis cycle only takes 2.5 minutes

  • RS485 output, support Modbus protocol

  • Password protection to prevent unauthorized operationl
