Halogen Amperometric Chlorine Sensors

The Halogen MP5™

Overview

A breakthrough for drinking water and wastewater monitoring, The Halogen MP5™ Multiple Parameter Sensor tests 5 parameters using a 3 electrode amperometric chlorine measurement. The MP5™ is unaffected by flow or pressure, is self-cleaning, automatically compensates for pH, and is certified for NSF-61 use. The MP5™ 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 MP5™ requires little to no maintenance, can be installed in a flow cell, directly in a pipe, or immersed in a tank, channel, or basin. Simple to install and inexpensive to operate, the Halogen MP5™ is unlike any other sensor on the market today.

Benefits of the 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 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 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 deplyment, the highly integrated design reduces the electronics cost and size, while increasing reliability.

Models and Deployment Types

MP5™ H1 Wet Tap (H1WT)

The Wet Tap (or Hot Tap) housing can be deployed as a retractable direct pipe insertion for NSF-61 usage. No-leak retractor options are available.

MP5™ H1 Mid Flange (H1MF-p)

The mid-flange housing (H1MF-P) and the associated 2″ adapter sleeve and collar kit make for an easy sidestream NSF-61 PVC Tee deployment.

H1 Low FLANGE (H1LF-P)

The low-flange model (H1LF-P) can be used to replace existing control-board-mounted setups or used as an NSF-61 submerged in-tank analyzer.

* RapidORP™ is HSI’s proprietary indicator for contamination. HSI’s measurement technique and self-cleaning system eliminate poisoning issues, providing a more reliable reading. HSI’s RapidORP™ measurement may have a slight offset from other sensors, it provides a reliable, qualitative measurement that overcomes many of the ORP problems.
