MP5™ Panel Mounted Chlorine Analyzer


This package will clean up your instrumentation panel, bringing all the benefits of the MP5™ online multi-parameter analyzer to a single wall-mounted solution. The combo includes an MP5™ with the low-flange housing (H1LF-P) coupled with a mountable flow cell and an operator’s choice of 24VDC (D1) or 120-240VAC (CN-01) 4-20 display module all designed to mount on an included machined backplate.

Why Use the MP5™ On a Panel?

Multiple Parameters in a Small Footprint

With a single MP5™ multi-parameter analyzer, operators can measure free chlorine, pH, temperature, conductivity, and Rapid ORP in one compact package, freeing up wall space and lowering maintenance time.

SensiCLĒNE™ Patented Self-Cleaning Technology

The MP5™ is unaffected by flow or turbidity, so it can be used in deployments where flow or pressure spikes occur.   In addition, the patented electrochemical cleaning SensiCLĒNE™ technology resists polarization and adsorption of organics.  Motivated by the flow from the pump, captive polymer 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. 

No Waste Stream

Approved for NSF-61 usage, water tested by an MP5™ can be sent right back into a drinking water tank, so no water is wasted for testing.

Easy to Monitor

The local 4-20 display contains (4) 4-20mA outputs (and is MODBUS capable) allows for onsite viewing of parameters, troubleshooting, and calibration of up to 5 separate MP5™ units.

Ease of Service

The annual wear-parts maintenance (for the SensiCLĒNE™ beads) takes only minutes and does not affect calibration.

MP5™ Models and Deployment Types

MP5™ H1 Wet Tap (H1WT)

Halogen MP5™ HotTap/WetTap Sensors

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)

Halogen MP5™ Sensors with PVC-tee Housing

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.


Halogen MP5™ Sensors with two types of flow-cell housings.

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.


Kit with flow-cell deployment (H1LF-P) and display controller  along with a wall mounting plate,  provides a drop-in upfit sensor replacement.

More Information

Battery power and remote telemetry for an MP5™ deployment. Use for outer grid monitoring, dead-ends, or other remote implementations.

More Information

Leverage the dependability and low maintenance of the MP5™ for remote tank monitoring with battery power and remote telemetry.

More Information

Retractable remover kit for MP5™ wet-tap analyzer (H1WT-P) in water pipes allows for maintenance without interrupting flows.

More Information

This deployment uses a water-proofed low-flange MP5™ (H1LF-P), a sourced boom and harness, or can simply be placed in a tank or trough.

More Information

Combine a mid-flange MP5™ (H1MF-P) with an adapter sleeve—in PVC or Stainless steel—sized for deployments in a 2″ PVC tee.

More Information

Fits low-flange MP5™ (H1LF-P) and adapts for side stream and control board usage based on which flow cell type  is ordered. 

More Information

Both 24V DC (D1) and 120-240V AC (CN-01) versions feature (4) 4-20 Ma analog outputs, and an M-12 Connector with stress relief.
