DPD Chlorine Analyzer

An online, multi-parameter colorimeter for industrial applications

Blue-I HYdroGuard HG-702 DPD Chlorine AnalyzerHYDROGUARD HG-702 is an online and modular colorimeter offering lab accuracy, even in harsh conditions, with reduced total cost of ownership (TCO).
HYDROGUARD HG-702 analyzer can be flexibly ordered to meet your specific needs and requirements, with any combination of up to 8 parameters in a single analyzer:

  • Free Chlorine or Total Chlorine
  • Free Chlorine and Total Chlorine
  • Conductivity
  • Turbidity
  • pH
  • ORP
  • Temperature
  • Flow

HYDROGUARD HG-702 pioneering colorimeter technology optimizes the implementation of high precision online measurements, long-term reliability and low maintenance. Its high-precision measurements excel even in challenging environments such as colored water, oily water, sea water, very low chlorine levels and high temperature. Furthermore, low measuring interval with 0.01ppm resolution and “0” reading make the HYDROGUARD HG-702 an ideal solution for performance-sensitive applications, such as food and beverage industry.
Accurate online measurements are ensured via automatic cleaning of the measuring cell, after each measurement, followed by zero reading calibration, which saves periodic maintenance expenses. Longer reagent expiration time reduces consumables and minimizes labor. The HYDROGUARD HG-702 superior performance, easy installation and minimized maintenance significantly reduce the product’s Total Cost-of-Ownership.
The HYDROGUARD HG-702 wide-ranging monitoring & control capabilities include multiple interfaces with external equipment using 4-20mA indication & control, alarm relays and industry standard Modbus protocol support.

This analyzer is compatible with WaterGuard
