Digital Redox ORP Regulator for sanitizing pools and aquariums — Temperature and humidity monitoring with recorded data
This instrument fits facility teams, storage operators, laboratories, and compliance users that need a practical way to capture data during building a reliable record of environmental conditions for quality, traceability, and troubleshooting.
Just set your ORP parameters and let the Milwaukee ORP Controller do the rest.
Extensively cited in water quality monitoring studies, the Milwaukee PRO digital ORP controller has been recognized for its precision in maintaining oxidation-reduction potential (ORP) in both residential and commercial settings. Industry reviews highlight its reliability, ease of use, and consistent performance, with many customers praising its fast readings and low-maintenance design. Popular applications include aquarium management, pool and spa water monitoring, hydroponics, and laboratory experiments, where accurate ORP levels are crucial for maintaining optimal water conditions.
The Milwaukee PRO digital ORP controller is preferred by people looking to dial in their testing program when they have an ongoing need to maintain levels. Common uses are aquariums, swimming pools and spas, and other water quality monitoring uses. The controller is accurate ±5 mV.
DESIGN FEATURES
- Fast, easy-to-read current results with large digital LCD readout
- Accurate to ±5 mV with user-selectable high/low set points
- Gel-filled, double-junction lab-grade Platinum ORP electrode for low maintenance and high performance included
- 6.5 feet probe cables for extra flexibility when testing
- 12 VDC power supply
AUTOMATION
The controller provides a control range of ±1000 mV with a user-selectable set point of 0 - 600 mV and a visual "Power Activated" LED indicator.
COMPATIBLE DOSING PUMP
Milwaukee includes a 12 VDC power plug socket compatible with Ozone Dosing units for automated treatment.
EASY INSTALLATION
The ORP Controller comes with a complete mounting kit, including a probe holder, for simple setup. The Milwaukee PRO digital Redox ORP controller automatically monitors and fine-tunes ORP levels.
CARE AND USE
Properly maintaining your ORP probe ensures fast, accurate results for longer periods.
Top Tips
- Always store with the cap full of buffer or storage solution, not water.
- Clean your probe regularly by soaking in cleaning solution.
- Calibrate after cleaning and/or storage before testing to adjust for any changes in the ORP probe sensor.
To broaden your aquatic water quality control and sanitation management beyond the Digital Redox ORP Controller for disinfection of pools and aquariums — a digital ORP regulator tailored to maintaining oxidation–reduction potential for effective sanitization in pools, spas and aquarium systems ([turn0search0](#)) — consider adding related monitoring and control products that strengthen your water chemistry workflows. The Milwaukee MC122 pH Controller delivers automated pH monitoring and setpoint control, supporting balanced water chemistry essential for disinfection and biological stability. For precise automated chemical addition to maintain set points, the Milwaukee MP810 Dosing Pump with Controller provides reliable peristaltic dosing that pairs with ORP or pH controllers to sustain optimal conditions without constant manual adjustment. Additionally, the Multiparameter pH/ORP/EC/Pressure/Temperature Waterproof Meter enables comprehensive field measurement of key water quality indicators such as pH, ORP, conductivity and temperature, giving deeper insight into the factors that influence pool or aquarium sanitation performance.
Technical Q&A
What is the typical lifespan of the ORP probe?
With proper maintenance, the gel-filled Platinum ORP probe can last several years, depending on usage and water conditions.
Can this controller be used with any dosing pump?
It is compatible with 12 VDC Ozone dosing units, but ensure the pump meets the controller’s voltage and connection requirements.
How often should I calibrate the ORP controller?
Calibration is recommended after each cleaning, storage period, or if the readings appear inconsistent.
Is the controller suitable for both fresh and saltwater aquariums?
Yes, the Milwaukee PRO ORP controller is designed for use in both freshwater and saltwater applications.
Does it require professional installation?
No, the controller comes with a complete mounting kit and instructions for easy DIY installation.
When is data logging especially valuable?
Logging is valuable when trends matter more than a single spot reading, such as curing history, storage conditions, verification records, or alarm-driven incident response.
Who is this best suited for?
Facility teams, storage operators, laboratories, and compliance users will get the most value when they need repeatable measurements plus a record they can review, export, or act on later.
Because it combines Range: +/- 1000 mv, Resolution: 1 mv, Accuracy: 5 mv, this product is a strong fit for temperature and humidity monitoring with recorded data where documentation and repeatability are important.
