Milwaukee pH54 Waterproof pH Tester with Replaceable Probe – Trusted pH Accuracy for Water Quality Enthusiasts & Professionals
Whether you’re fine-tuning a hydroponic system, caring for an aquarium, or verifying the pH of your irrigation water, precision pH measurement is the foundation of success. The Milwaukee pH54 Waterproof pH Tester has been designed for one purpose: to deliver accurate, reliable, and hassle-free pH readings, even in challenging environments.
Trusted by growers, aquarists, educators, and environmental professionals worldwide, the pH54 combines accuracy, durability, and affordability in a handheld, waterproof tester that’s easy to use and maintain. From hydroponic growers adjusting nutrient solutions, to waste water technicians monitoring effluent, to aquarists keeping aquatic life in balance –Milwaukee’s pH54 provides fast, dependable results where they matter most.
Unlike single-use testers or fragile meters, the pH54 offers along-lasting solution thanks to its replaceable, double-junction probe andIP65-rated waterproof casing. Calibration is fast and straightforward with simple, manual one- or two-point calibration. Its compact size fits easily in a pocket or toolbox, ready to support you on-site or in the lab whenever you need precise pH measurement.
Because when water quality is your business – or your passion – there’s no time for guesswork.

Horticulture & Agriculture
Monitor irrigation water and soil slurries to optimize pH for crop performance, from greenhouse operations to open fields.
Water & Wastewater Treatment
Ideal for technicians monitoring pH in effluents and process streams to ensure regulatory compliance and treatment efficiency.
Education & Laboratories
Perfect for teaching environments, research labs, and field studies –offering hands-on experience with professional-grade accuracy.
Food & Beverage Production
Supports quality control processes where water pH impacts flavor,safety, and consistency (brewing, wine making, cheese making, etc.).
Pools & Spas
Ensures balanced water chemistry for safety, comfort, and equipment protection.
Environmental Field Testing
Robust enough for fieldwork, whether monitoring rivers, lakes, or runoff for ecological assessments.
Proper Care & Maintenance
A pH tester’s performance relies heavily on the condition of its probe. To extend the life and accuracy of your Milwaukee pH54, follow these care guidelines:
Storage
- Never store the probe dry. Dry storage damages sensitivity and risks clogging the reference junction.
- Use storage solution or pH 4.01/7.01 calibration buffer to keep the probe hydrated. Avoid tap or distilled water.
- Store the electrode upright with storage solution in the cap to prevent leakage and dehydration.
Cleaning
- Residue buildup from samples can affect accuracy. Regular cleaning with electrode cleaning solution prevents contamination and restores performance, especially after exposure to organic-rich or protein-heavy samples.
Calibration
- Calibrate regularly – before each use if possible, or at least weekly for continuous reliability.
- Always recalibrate after cleaning or extended storage periods.
- The pH54 supports easy 1- or 2-point calibration for fast and accurate results.
