General Overview


A breakthrough for ballast water monitoring, The Halogen System TRO Multiple Parameter Sensor tests 5 parameters using a 3-electrode amperometric chlorine measurement. The sensor is unaffected by flow or pressure, is self-cleaning, and automatically compensates for pH. The TRO sensor utilizes Halogen’s patented RapidResponse ORP™ technology, a specialized implementation of ORP measurement that will report more consistent numbers thanks to a high resistance to poisoning.

The HSI sensor requires little to no maintenance, can be installed in a flow cell or directly in a pipe. Simple to install and inexpensive to operate, the Halogen TRO sensor is unlike any other ballast water analyzer on the market today.

Unique Features

  • 5 Parameters in a single online near-time analyzer
  • Self-cleaning & low-maintenance
  • No membranes or electrolyte
  • Factory calibrated, minimal drift
  • Flexible deployment types
  • System is equipped with 4 20mA and MODBUS RTU. Other communication protocols are available upon request.
  • 24 VDC or 90 to 240 VAC operation

Key Features

Flow Independent Measurement 

The sensor is unaffected by flow velocity changes from 0 to 4 m/s. An integrated pump that utilizes a long-lasting, brushless motor delivers a fixed velocity across the electrodes, creating flow independence in any installation. The high-velocity flow across the electrodes improves sensitivity and lowers the Signal to Noise Ratio.

Ease of Service

A Wet Tap installation method enables direct insertion into a distribution pipe. Sidestream, deployments are available. Whatever deployment, the highly integrated design reduces the electronics cost and size while increasing reliability.

SensiCLĒNE™ Patented Self-Cleaning Technology

A patented electrochemical cleaning method called SensiCLĒNE™  resists polarization and adsorption of organics.  Cleaning beads continuously abrade the sensor. This keeps the electrode surfaces, including the pH sensor, free from buildup, scaling, and biofouling. Solid metal electrodes last the life of the system. 

These features combine to enable very long intervals between calibrations.  

Easy to Monitor

An optional local Display is available for viewing parameters, troubleshooting and calibration of up to 5 separate MP5™ units.
