Portable pH Testing
Check acidity or alkalinity at the sampling point and compare portable options for focused photometry or wider field investigations.
What does pH show?
pH expresses how acidic or alkaline water is. It influences chemical reactions, treatment performance, corrosion, biological activity and the behaviour of other measured substances, so a well-controlled portable result can provide essential field context.
Read the USGS guide to pH and water for authoritative background. Return to our portable water-quality parameters guide to compare other measurements, or visit PMA for wider water and wastewater instrumentation support.
Where portable pH testing is useful
Portable instruments for pH
The correct instrument depends on the measurement method, expected range, water matrix, other parameters and how results need to be recorded.
MD 100 portable photometer
A compact photometer available with pH and chlorine parameter combinations for routine water testing.
Best for: focused, portable photometric checks.
View MD 100
MD 610 multiparameter photometer
A connected multiparameter photometer for pH and a wider menu of reagent-based water tests.
Best for: teams needing stored results and several photometric methods.
View MD 610
Section 82 water-quality kit
A complete field kit combining pH with dissolved oxygen, temperature, conductivity, turbidity and ammonia.
Best for: broader environmental and incident investigations.

Portable pH testing FAQs
What does portable pH testing show?
pH expresses how acidic or alkaline water is. It influences chemical reactions, treatment performance, corrosion, biological activity and the behaviour of other measured substances, so a well-controlled portable result can provide essential field context.
Where is portable pH testing useful?
Common uses include drinking-water and wastewater treatment, pool and spa water testing, industrial process and discharge checks, river and catchment investigations. The best sampling point should always be chosen around the decision the result needs to support.
Which portable instrument can measure pH?
MD 100 portable photometer and MD 610 multiparameter photometer and Section 82 water-quality kit provide different levels of capability. The preferred option depends on the method, range, sample and other parameters.
Can a portable result help verify an online analyser?
Yes. A carefully collected portable result can provide an independent spot check during commissioning or investigation. Sampling location, timing, preparation and method differences must be considered before comparing readings.
What information should I provide before requesting a quote?
Share the water type, expected range, sampling location, testing frequency, other required parameters, record-keeping needs and any site constraints. This helps PMA confirm the complete practical package.
Can PMA help select the correct method and equipment?
Yes. PMA can review the application, expected conditions, measurement method, reagents or sensors, calibration needs and supporting accessories before quotation.
