Why Choose the Halogen MP5™?

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.

SensiCLĒNE™ Patented Self-Cleaning Technology

A patented electrochemical cleaning method called SensiCLENE™  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 calibration.

No Waste Stream

Because the sensor is approved for NSF-61 usage, it can be installed as a side-stream unit, directly in a pipe, or submerged in a tank with no required waste stream.

Easy to Monitor

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

Ease of Service

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

Simple & Flexible Installation

Wet Tap Installation

Wet tap installations for the Halogen MP5™ Chlorine Analyzer are often cost-effective when compared to other installation methods. The Wet Tap method of installation eliminates the need for significant modifications or additional infrastructure.

PVC-Tee Installation

The mid-flange housing (H1MF-P) and the associated 2″ adapter sleeve and collar kit make for an easy side stream NSF-61 PVC Tee deployment. This configuration fits an OTS 2” PVC Tee and requires a  threaded adapter (PT-01).

Maintenance Schedule

  • 1 yr replace SensiCLĒNE™wear-parts.
  • 2 yr replace the pH Sensor
  • 5 yr Recommend factory rebuild to replace motor assemble and any worn parts.
