Which parameters does it cover?

Free chlorine, total chlorine, pH, total alkalinity, calcium hardness, cyanuric acid.

Within 5% of laboratory reference, far better than colour-match strips.

Around 1000 tests per fresh set of 2x AA batteries.

Photometer, sample cell, starter pack of reagent tablets (10 of each parameter), instruction manual, carrying case.

Refill tablets sold separately?

Yes. 100-count tubs by parameter. Re-stocking is straightforward.

Strips or photometer?

Strips for daily speed; photometer for accuracy and audit trail. Many serious owners use both.

What is the wavelength?

525 nm LED, the analytical wavelength for DPD chlorine and most pool reagent chemistries.

How is it calibrated?

Factory calibrated; field calibration via reference standard solutions monthly recommended for service businesses.

Does it record readings?

Yes. Stores last 100 readings in memory for trend logging.

Clean cell; use fresh reagent; ensure full dissolution.

Recalibrate monthly with reference solution; replace cell if optical face is scratched.

Photometer vs strips?

Photometer is quantitative and audit-friendly; strips are colour-match and faster. Strips for daily, photometer for weekly verification.

Photometer vs liquid drop kit?

Photometer reads digital; liquid kit reads colour drops manually. Same accuracy class but photometer is faster and logs readings.
