Portable Chlorine Testing
Compare practical portable photometers for free and total chlorine checks across drinking water, pools and industrial water systems.
What does chlorine show?
Chlorine measurements help operators confirm disinfection conditions and check residual levels through treatment and distribution. Portable photometry provides a numerical field result when the correct method, reagent and sample preparation are used.

Where portable chlorine testing is useful
Choose the chlorine test
Confirm whether the task requires free chlorine, total chlorine or both, and the range you expect at the sampling point. Plan a repeatable routine from sample collection through reagent addition and reading. A distribution check, a pool-water test and a process-water investigation may need different test programmes.
Portable instruments for chlorine
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, rugged photometer available in parameter combinations that include free and total chlorine and pH.
Best for: straightforward routine chlorine testing with a focused instrument.

Portable chlorine testing FAQs
What does portable chlorine testing show?
Chlorine measurements help operators confirm disinfection conditions and check residual levels through treatment and distribution. Portable photometry provides a numerical field result when the correct method, reagent and sample preparation are used.
Where is portable chlorine testing useful?
Common uses include drinking-water treatment and distribution, pool and spa water checks, food and beverage process water, cooling-water and industrial systems. The best sampling point should always be chosen around the decision the result needs to support.
Which portable instrument can measure chlorine?
MD 100 portable photometer and MD 610 multiparameter photometer 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.
