Plain-language reference

Pool monitor, probe, or controller? Start with the job.

See what each tool does, what it does not do, and which terms matter before you compare products.

Short answer

Pool terms can name more than one job. A tester runs a test. A monitor sends a read. A controller may act on a read. A feed pump adds a pool product. A route app plans the work.

Use the plain terms below when you shop. Two tools can sound alike in an ad and still do a very different job.

Product and workflow terms

Automatic pool water tester

A unit that runs a pool test on its own. The word does not tell you the test type or run times. It does not tell you what it tests or if it can run other gear.

Pool monitor

A tool that reads, shows, saves, or sends pool data. Check if it uses a wet probe, liquid test, gear link, or hand note.

Pool controller

A tool that can use a read or set point to run linked gear. Some can run a pool feed. The tool is not, by itself, a full test or pool rule plan.

Chemical feeder or doser

Gear that adds a pool product to the water. You must still check the water and gear. Follow the label and local pool rules.

Pool route software

An app used to plan visits and give out work. It may keep client notes, log jobs, or help run the firm. It is not a pool test unit.

Exception

A read, missed test, gear issue, or call that needs a check off the main route plan.

Alert

A note that a set event took place. An alert needs an owner and a check plan. It is not a cause, a fix, or a dose.

Technician handoff

A note for the next pool tech. It gives the facts, test, check, work, owner, due time, and next step.

Test-method terms

Liquid-reagent test

A test that mixes pool water with a liquid. The mix makes a change that can be read. The test steps, liquid, pool sample, and test range still matter.

Immersed probe

A wet sensor that makes an electric pool read. Each probe reads its own thing. It has its own care needs and test range.

ORP

ORP means oxidation-reduction potential. It is an electric read in millivolts. ORP is tied to the state of the water. It is not the same test as free chlorine.

Manual test

A test done by a person with the right kit. A hand test can be good or bad. The test, pool sample, liquid, care, and log all matter.

Scheduled testing

Tests that run at set times. Amano normally tests twice a day. You can change the time and rate. A set test is not a live feed.

Verification

A check of a pool read. Use the right test, pool sample, unit, range, gear facts, and site rules.

Water-chemistry terms

Free chlorine

The chlorine read as ready to kill germs in the named test. Read it with pH, CYA when it fits, site facts, and local pool rules.

Combined chlorine

A part of the chlorine test tied to chloramine. It is not the same as free chlorine.

pH

A read of the water’s acid or base state. pH can change pool balance and how you read other tests. One pH read does not show the cause.

Total alkalinity

A read of how the water can fight a fast pH change. It is tied to pH. It is not the same test.

Cyanuric acid (CYA)

A pool aid that can change how chlorine works in the sun. It can change how you read the chlorine test. Amano does not test CYA.

Rules and evidence terms

Authority having jurisdiction (AHJ)

The local group or inspector in charge of the site rule. The group can change by place.

Model Aquatic Health Code (MAHC)

A CDC pool guide. A local group may use it, change it, or skip it. It is not US law. See the CDC MAHC page.

Facility SOP

The site’s set work plan. It should use local rules, gear guides, the pool firm deal, product labels, and named roles.

These terms are a broad guide. Local pool rules, your site plan, product labels, gear guides, and the current tool guide control the work.

Common questions

Is a pool monitor the same as a pool controller?
No. A pool monitor tests or logs. A pool controller can use a read to run gear or a feed pump. Each tool has its own jobs. Check the tool guide.
Is scheduled testing continuous monitoring?
No. Set tests run at planned times. A live tool checks far more often. Amano normally tests twice a day. You can change the test times and rate.
Does ORP equal free chlorine?
No. ORP is an electric pool read. It is tied to the state of the water. It is not the same as a liquid free chlorine test.
Does Amano measure cyanuric acid?
No. Amano tests free chlorine, combined chlorine, pH, and total alkalinity. Get and log any CYA test that your pool rules need.

Use the terms to pick the right tool

Start with the job you need done. Then compare the test method, records, dosing work, and route workflow.
