A pH measuring device is essential in sectors where consistency matters:

  • Agriculture: Soil pH affects fertiliser use and crop planning
  • Environmental research: Use a pH water tester to monitor lakes, rivers, and aquifers
  • Healthcare: Pathology and research labs measure pH in controlled environments
  • Construction: A pH reader supports material testing and waste monitoring
  • Transport: Industries use pH testing equipment to check run-off and fuel systems
  • Government: Used in field audits, compliance work, and quality assessments
  • Education: Teachers and students can use a digital pH tester in classrooms and field studies

Whether you need a portable pH meter, digital pH tester, or benchtop device for lab, field, and industrial use, you’ll find it here in our range.

Why Use a pH Tester?

pH measurement affects safety, efficiency, and decision-making across many sectors. A shift in water acidity can damage crops, affect drinking water, or alter chemical reactions. 

That’s why using an accurate pH reader is critical in:

  • Food and beverage industry: Maintaining proper pH levels is critical to ensure product safety, flavour consistency, and regulatory compliance. 
  • Education and research: pH testing helps students and researchers understand chemical reactions, environmental changes, and biological processes.
  • Environmental testing: pH levels indicate pollution risks or help track natural changes in ecosystems.
  • Agriculture: The pH of soil and irrigation water impacts nutrient uptake and overall plant health. 
  • Water treatment: pH control ensures safe drinking water, effective chemical dosing, and corrosion prevention.
  • Aquaculture and fisheries: A pH meter for water helps maintain balanced conditions for optimal growth and survival rates.
  • Construction and engineering: pH values influence the setting of concrete and the corrosion rate of materials. 
  • Health services depend on correct pH levels in both biological and lab samples. 

If you need a pH meter for water, soil, or industrial process control, we’ll help you choose the right model based on your needs. Contact our team of scientists today for further advice.

Conditions in the field can be unpredictable. A portable pH meter should work just as well on a hot farm as it does in a cooled lab. 

Our gear is selected to handle moisture, dirt, and changing temperatures. We support each pH reader with clear guides and advice from local experts.

Find the Right pH Reader

We stock handheld pH meters for quick checks, portable units for multi-site testing, and electronic pH meters for high-precision lab work. Our range includes:

  • Electronic pH meter with large displays and rechargeable batteries
  • pH tester for water in pools, tanks, and natural sources
  • Digital soil pH meter for farmers and land care workers
  • pH meter probe for lab, food safety, or environmental kits
  • pH measuring device for continuous or batch processing in industrial settings

Many models feature automatic calibration, temperature compensation, and data storage. Some include multi-parameter readings for conductivity, ORP, or dissolved oxygen. We also carry accessories such as buffer solutions, probe storage liquids, and spare electrodes.
