Does this pool need a monitor or a controller?

Amano tests and logs. A controller may run chemical feed gear. Pick the job before you pick the tool.

Short answer

Amano is a pool monitor. It sits on a pool return line. It runs liquid tests and saves the test time. It does not add pool chemicals.

A pool controller may start a feed pump. It may act when a probe hits a set point. A salt cell makes chlorine from salt. Those are not the same jobs.

This page does not score brands. It helps you pick the right tool.

What a monitor does

A monitor tests and logs. Amano tests free chlorine, combined chlorine, pH, and total alkalinity. It normally tests twice a day. You can change the times. Amano can send an alert after a test. It can share the log with a QR code.

It uses liquid reagent, not a wet ORP probe. Read liquid test versus probe. A liquid tester does not have to be a doser.

What a controller may do

A controller can act on the water. Many read ORP, pH, or both. Wet probes send those reads. The panel may start a pump or valve. That gear can feed a pool product.

You must still check the probes, feed gear, label, and water. A bad set point can feed too much or too little. So can a dirty probe.

Chemtrol and PoolPal are names in this class. Amano has no tie to them. We do not claim that Amano links to them.

What a salt cell may do

A salt cell makes chlorine from salt in the pool. Some kits add a control panel. A salt cell does not make the same four-read liquid log. It does not take the place of a hand test.

Amano does not make chlorine. It does not run a salt cell.

How the jobs sit side by side

Tool jobs, not a score
Job Monitor (Amano) Typical controller Typical salt system
Main work Set tests and time-marked logs Read a probe and feed a product Make chlorine from salt
Adds chemicals No Yes, when set to feed Makes chlorine; not a four-read log
Usual signal Liquid test: FC, CC, pH, TA Often ORP and pH probes Cell output and salt level
Replaces the operator No No No
This is a broad guide. Follow local pool rules, your site plan, product labels, and gear guides. MAHC is a guide, not US law.

Does the site have feed gear now? Check it with the pool tech and gear maker. Amano may fit on the 2-inch return line. It can log its four reads. It does not take over the feed gear.

Common questions

Does Amano dose chemicals like a controller?
No. Amano runs liquid tests at set times. It saves each result and test time. It does not open a chemical line or feed a pool product.
Is Amano an ORP controller?
No. An ORP tool reads a wet probe. It may start a feed pump at a set point. Amano uses liquid reagent for four pool reads. It does not run a feed pump.
Can Amano replace a salt chlorine generator?
No. A salt cell makes chlorine from salt in the water. Amano only tests and logs four pool values. It does not make chlorine.
If I already have a controller, do I still need manual tests?
Yes. These are just tools. Keep the CPO, hand tests, and site checks. Follow local rules and product labels. Amano does not take on those jobs.
Which system scores higher?
This page does not rank brands. Pick the job you need: test and log, feed a pool product, or make chlorine. Then follow your site plan.
