How does the MP5™ require so little maintenance?
The MP5™ features a patented self-cleaning technology called SensiCLĒNE™. This technology uses an impeller to cycle special polymer beads over the sensor electrodes and pH probe. This continuous cleaning prevents buildup and fouling, reducing the need for frequent manual intervention. Unlike traditional sensors, it requires no membranes or reagents to replace, and its stable calibration can last for months—sometimes up to a year—minimizing upkeep.
Why can the MP5™ be installed anywhere?
The MP5™ is designed with flexible installation options due to its small footprint, flow independence, and durability. It can be inserted directly into a pipe (wet-tap), installed in a PVC tee, submerged in a tank, or used in a flow cell. Its NSF-61 certification allows it to be placed in drinking water systems without a waste stream, and it withstands pressures up to 10 bar (150 psi) and a wide range of conditions, making it adaptable to various environments.
What maintenance is required?
Maintenance is minimal. A calibration check is recommended every 60 days, with a pH calibration check annually. The wear parts—impeller, o-rings, cleaning beads, and screen—should be replaced yearly, and the pH sensor cartridge every two years. These tasks are quick, taking just minutes, and don’t typically affect calibration, thanks to the SensiCLĒNE™ system.
Do I have to be concerned about flow or pressure changes in the installation?
No, the MP5™ is unaffected by flow or pressure variations. Its integrated pump maintains a consistent flow across the electrodes, ensuring accurate readings regardless of external conditions. The range of flow is zero to 4 m/s, and the pressures range from 0 to 10 bar. This flow independence eliminates the need for complex flow-control plumbing.
Will it work in zero flow?
Yes, the MP5™ operates effectively even in zero-flow conditions. It’s built-in pump generates its own flow across the electrodes, ensuring reliable measurements without relying on external water movement. This makes it ideal for static environments like tanks or pipes with intermittent flow.
How does the sensor measure Monochloramine and Free Chlorine on the same sensor?
The MP5™ uses advanced amperometric technology with a three-electrode system, enhanced by onboard pH and temperature compensation. The MP-TOTAL™ variant, built on the MP5™ platform, is specifically noted for measuring Monochloramine and Free Chlorine alongside other parameters like pH, conductivity, and ORP. This multiparameter capability is achieved through precise electrochemical detection tailored to distinguish these chlorine species.
How is the Monochloramine/Free Chlorine sensor different from Total Chlorine measurement?
The MP5™ (and MP6™) can measure Free Chlorine and Monochloramine as distinct parameters, while Total Chlorine includes free and combined chlorine (like Monochloramine). The sensor’s ability to differentiate Free Chlorine and Monochloramine provides more specific data, whereas Total Chlorine is a broader measurement often used in applications like ballast water (TRO). The MP5™ can be configured for either, depending on the need, with Monochloramine measurement being a feature of the MP-TOTAL™.
How can I install the MP5™ Chlorine Analyzer in an active pipeline?
The MP5™ offers a wet-tap (or hot-tap) installation option, allowing it to be inserted directly into an active pipeline without interrupting flow. A retractable remover kit (e.g., H1WT-P) facilitates this process, enabling maintenance or removal without shutting down the system. This is supported by its NSF-61 certification and robust design, which handles pressures up to 150 psi.
Does the sensor have a “memory” if it is not exposed to chlorine for hours or days?
The MP5™ doesn’t suffer from a “memory effect” after prolonged absence of chlorine. Its pH cartridge is designed to rapidly rewet and restore accuracy within 3 minutes of reimmersion, even if it dries out. The sensor stabilizes within 5 minutes of installation or re-exposure, and its calibration remains intact, unaffected by dry periods or lack of chlorine.
Are Halogen Systems Inc. Family of Chlorine Analyzers Build America Buy America (BABA) compliant?
Yes.
Can I try the chlorine analyzer before I buy it?
Yes, for qualified buyers.
What is the warranty on the analyzers?
1 year.
We have pressurized pipes, tanks, open channels – would there be a situation or condition where the analyzer would not be ideal for?
Bubbles are the main interference. Areas with cavitation or turbulence should be avoided.
Are the analyzers also manufactured in the US?
Yes, and they are BABA compliant.
How long is the chlorine probe itself anticipated to last before it needs to be replaced?
5 years, then the sensor is rebuilt.
Are both the MP-TOTAL and MP5 analyzers are NSF 61 certified?
Yes, all our sensors, cables, flow cells, and components are certified compliant with NSF61/372.
If an MP5 Side Stream sensor is used, can the waste stream be returned to the process or tank?
Yes. All of the wetted components are NSF-61 Certified.
