2-in-1 Digital pH / ORP Controller w/Mounting Kit, 4 to 8 pH
The Milwaukee MC125 PRO pH and ORP controller is designed for people looking to measure and adjust pH and ORP levels automatically with one simple controller. Just set your pH and ORP parameters and let the Milwaukee pH Controller do the rest. The Milwaukee PRO pH / 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 nutrient tanks, aquariums, pools, and spas. The Milwaukee PRO 2 in 1 controller offers an accuracy of ±0.2 pH with two-point manual calibration and ORP accuracy of ±5 mV. See real-time pH and ORP measurements from 0.00 pH to 14.00 pH and -1000 mV to 1000 mV with a large LED with easy switching between parameters. The controller provides a control range of 4 to 8 pH and -200 to 600 mV. Just set your control range and the controller does the rest. Choose your device including oxygen pumps, CO2-regulators, O3 ozonizers, and other pH & ORP control devices by simply plugging the device into the correct pH or ORP outlet.
Properly maintaining your pH and ORP probes will give you fast, accurate results for longer. pH and ORP probes are similar in design but there are some differences.
pH probes have a sensing bulb that loses sensitivity with age. All pH sensors have a limited life and response time gets longer with age.
ORP probes have usually a platinum electrode instead of a glass bulb. This electrode has a longer life but can have a residue build-up that affects response rates and accuracy.
Both electrodes have a reference junction that can become clogged resulting in slow and inaccurate results. Cleaning and keeping the probe hydrated will help prevent this.
