I-monitor ye-IAQ esanda kwethulwa kaTongdy i-EM21 iyisiqaphi sekhwalithi yomoya sangaphakathi esinomklamo oyingqayizivele kanye nemisebenzi ehlangabezana nezidingo ze-Class B zebhizinisi. Ukuqapha kwe-PM2.5, PM10, CO2, TVOC, izinga lokushisa, umswakama, i-formaldehyde amahora angama-24. Ine-algorithm yokulinganisa yokulinganisa eyingqayizivele enamapharamitha amaningi kanye nesinxephezelo senani lokulinganisa esakhelwe ngaphakathi ukuqinisekisa idatha ethembekile nenembile ezindaweni ezahlukene. I-EM21 iphinde inikeze izinketho zokuqapha zesikhathi sangempela zomsindo wemvelo kanye nokukhanya kokukhanya.
I-EM21 inezindlela ezimbili zokufaka, ukufakwa okufakwe odongeni noma ukufakwa odongeni ngebhokisi lokufaka (imibala emi-4 ingakhethwa). Ingafakwa futhi kudeskithophu.
I-EM21 inokubukeka okunesitayela. Abasebenzisi bangakhetha ukungabonisi, futhi ukukhanya okunemibala emithathu kubonisa amazinga amathathu ekhwalithi yomoya. Ungakhetha futhi isibonisi sesikrini se-LCD, esinenzwa ezwela ukukhanya eyakhelwe ngaphakathi, futhi ukukhanya kwesikrini sokubonisa kungalungiswa ngokuzenzakalelayo ngokuya ngokukhanya okuzungezile emini nasebusuku.
Njengesiqaphi somoya sangaphakathi esisezingeni lezentengiselwano, i-EM21 ine-data logger eyakhelwe ngaphakathi futhi isekela i-Bluetooth ukuze ilande idatha. I-EM21 ilayisha idatha efwini ngesikhathi sangempela, futhi abasebenzisi bangabuka idatha yesikhathi sangempela kanye nedatha yomlando nganoma yisiphi isikhathi nge-PC kanye nohlelo lokusebenza lweselula. Hlaziya, uhlole, futhi uqaphe njalo ikhwalithi yomoya wangaphakathi. Lawula ngokunembile umoya omusha kanye nohlelo lokuhlanza ukuze uzuze ukonga amandla ngenkathi wanelisa ikhwalithi yomoya enhle. Isetshenziswa kabanzi ezindaweni zomphakathi zangaphakathi kanye nasezindaweni zokuhlala, kufaka phakathi izindawo zezentengiselwano, izikole, amahhotela kanye nezindawo zokuhlala.
