Ano ang DOZ201 single-parameter ozone analyzer?

Ang DOZ201 ay isang handheld colorimeter na ginawa para sa single-parameter ozone (O3) measurement, sumasakop sa 0-2.50 mg/L na may 0.01 mg/L reading division. Ang 525 nm LED source at reagent chemistry ay ginagawa itong praktikal na tool para sa ozone disinfection verification sa drinking water, food at low-level checks.

Pinapagana ng apat na AAA batteries para sa mahigit 40 oras na tuloy-tuloy na paggamit at tumitimbang nang humigit-kumulang 220 g, madali itong dalhin sa pagitan ng field, planta at lab. Ang reading ay ipinapakita nang direkta matapos ang timed colour reaction, kaya hindi kailangan ng calibration curve ang operator.

Saan ginagamit ang DOZ201?

Drinking-water at bottled-water plants na nagpapatibay ng ozone residual pagkatapos ng disinfection.
Food, beverage at pharmaceutical lines kung saan ginagamit ang ozone para sa sanitasyon at dapat i-verify.
Environmental at third-party labs na nagpapatakbo ng routine ozone-residue checks.
Aquaculture at pool / spa operators na nagmo-monitor ng ozone treatment effectiveness.
Hospitals at cooling-water systems na gumagawa ng spot checks ng disinfection.

Mga paalala sa pagpili

Ang DOZ201 ay specific sa ozone gamit ang matched reagent; gamitin ang dedicated meter para sa chlorine o chlorine dioxide.
Gawin ang test sa 0-40 C at below 90% relative humidity, at panatilihing malinis at tuyo ang optical cell.
Gumamit ng sariwang reagent at malinis na 10 mL sample vessel; i-record ang reading matapos ang specified reaction time para sa repeatable results.

Mga madalas itanong

Kailangan ba ng DOZ201 ng calibration curve?

Hindi. Bumabasa ito nang direkta mula sa timed colour reaction ng single-parameter reagent, kaya hindi bumubuo o nag-iimbak ng curve ang operator.

Ano ang pinakamababang value na maipapakita nito?

Ang reading division ay 0.01 mg/L, kaya nakakaresolba ang meter ng pagbabago hanggang 0.01 mg/L sa buong 0-2.50 mg/L span.

Gaano katagal ang battery sa field?

Apat na AAA batteries ay nagbibigay ng mahigit 40 oras na tuloy-tuloy na operasyon, sapat para sa extended field o shift use.

Kaya ba nitong sukatin ang chlorine o chlorine dioxide?

Hindi. Ang DOZ201 ay specific sa ozone; ang multi-parameter analyzer ang sumasakop sa chlorine at chlorine dioxide.
