Kusintha kwakukulu pakujambulidwa kwa kutentha kwa thupi la munthu kwakhala kukuchitika padziko lonse lapansi m'zaka zaposachedwa.
Inde, mutha kugwiritsa ntchito cholinga chambiri Medical infrared thermometer kuyeza kutentha kwa munthu kudzera mu ngoma ya khutu kapena pamphumi.
Munthawi ya COVID, chifukwa chomwe chojambulira kutentha kwa infrared chimakhala ndi malo ofunikira kwambiri pakuyambiranso ntchito ndi kupanga chifukwa cha zabwino za chowunikira kutentha kwa infrared, chomwe chimatha kugwira ntchito mosalumikizana, maola 24 patsiku, popanda kufunikira kwa mgwirizano wa ogwira ntchito oyesedwa, komanso osazindikira kutentha; Ogwira ntchito oyezedwa amatha kumaliza kuyeza kutentha popanda kuyimitsa pakuyenda kwanthawi zonse, ndipo kuyeza kwa kutentha mwachiwonekere ndikokwera kwambiri kuwirikiza katatu kuposa kuyeza kwa kutentha kwapamanja.
Mfundo yogwiritsira ntchito thermometer ya infrared ndi yakuti m'chilengedwe, kuwonjezera pa kuwala komwe kungathe kuwonedwa ndi maso a anthu (omwe nthawi zambiri amatchedwa kuwala kowonekera), palinso kuwala kosaoneka monga ultraviolet ndi kuwala kwa infrared. Chilichonse chokhala ndi kutentha kwakukulu kuposa zero (- 273 ℃) m'chilengedwe chimawunikira mafunde amagetsi (ma infrared ray) nthawi iliyonse. Chifukwa chake, kuwala kwa infrared ndiye mafunde amagetsi ofala kwambiri m'chilengedwe, ndipo kuwala kwa infrared sikungatengedwe ndi utsi ndi mitambo. Ndi chitukuko chofulumira cha sayansi ndi ukadaulo, ma radiation a infrared amagwiritsidwa ntchito kuzindikira ndikuyezera ma radiation yamafuta pogwiritsa ntchito kuphatikiza ukadaulo wamagetsi, mapulogalamu apakompyuta ndiukadaulo wa infrared.
Ma thermometers a infrared a anthu amakhala ndi IR probe, electronic circuitry, microprocessor, ndi LCD kapena LED zowonetsera.
Thermometer ya thupi la munthu imayesa kutentha poyesa kutentha kochokera ku chinthu choyezedwa (pamwamba pa thupi la munthu, khutu la khutu, ndi zina zotero) kupyolera mu chowunikira. Choncho, pamene munthu woyezedwa ali pafupi kwambiri ndi thermometer, m'pamenenso amakwera molondola.
Zoyezera pamphumi za Joytech infrared ziyenera kugwiritsidwa ntchito mkati mwa 3cm mpaka 5cm. Muyezo wachiwiri wa 1 umapangitsa kuyeza kwa kutentha kukhala bwino kwambiri.
Joytech infrared thermometer DET-3011 yokhala ndi mutu wa probe wosinthasintha idzakhala chisankho chabwinoko pa chipangizo chanu chowunikira kutentha kwanyumba.
