Kunezindlela ezingaba yishumi nambili zokukala
Umzimba. Lokhu kuvame ukwenziwa ngama-thermometers we-mercury. Kepha manje ekuthengisweni ungathola imivimbo enqunu, infrared, Galaline, Thermometers Electronic. Cabanga ngezinhlobo ezi-4 ezivame kakhulu zama-thermometer, silinganisela izinzuzo zazo futhi
.
I-Mercury Thermometer
Izinzuzo:
Izinga lokushisa likalwa iningi labantu endleleni. I-thermometer enjalo iyi-flask yengilazi ene-capillary equkethe i-mercury. Kwesinye isikhathi le-thermometer ibizwa ngokuthi ubukhulu, ngoba iMercury ingavuka iphuzu lokugcina lokushisa futhi aliwi ngaphandle kokuzamazama.
Okubi:
I-Thermometer ye-Mercury ibhekwa njengengozi kakhulu ngenxa yeMercury, naphezu kweqiniso lokuthi libonisa umphumela onembe kakhulu. Kepha uma ephuka, iMercury ingadala izinkinga ezinkulu. Amabili ngababili banobubi obubi empilweni yabantu.
Funda futhi: Yini abazali okufanele bayenze uma ingane inokushisa okuphezulu?
Galnistanderdeermometer
Izinzuzo:
Kubukeka sengathi kubukeka sengathi kufana ne-thermometer ye-mermury, kodwa empeleni akukho ngqondo ngaphakathi. Esikhundleni sayo - ingxube yezinsimbi ezinjalo ze-liquid njengeNdiya, iTin and Gallium (Galinstan). Akunangozi ngokuphelele kubantu. Ukuhlukaniswa kwe-thermometer enjalo ngeke kulimaze impilo yabantu.
Okubi:
Kunobudlova obunzima be-thermometer enjalo - kunzima kakhulu ukwehlisa inkomba yokulinganisa kabusha izinga lokushisa lomzimba. Inhlanganisela yensimbi ihamba eceleni kwe-tube yengilazi enobunzima obukhulu ngokungafani ne-mercury. Futhi ukuze i-thermometer enjalo ikhombisa umphumela onembile, udinga eduze komzimba. Uma lesi simo singabonakali, izinga lokushisa lingase lingalungile.
I-Digital Thermometer
Izinzuzo
Ukubukeka kwanamuhla. I-thermometer enjalo iyi-tube yepulasitiki enesibonisi, i-wiring translucent ngokusebenzisa izindlu. Ibonisa umphumela ucacile, ukukala izinga lokushisa kuvame ukuthatha kusuka emizuzwini emi-3 kuye kwayi-5. Lapho isilinganiso sokushisa sesiphothuliwe, umsindo we-beep. Inani lokugcina lokushisa okulinganiselwe kudivayisi ligcinwa.
Okubi
I-lermometer ye-elektroniki inezinkinga ezimbili eziyinhloko. Izindleko eziphakeme futhi amathuba okuthola umphumela ofanele ngokufanelekile emzimbeni. Kunzima ukuba nezingane ezincane ziyeka endaweni, ngakho-ke kuvame ukuba yi-thermometer enjalo kukhipha i-thermometer enjalo.
I-thermometer ethambile
Izinzuzo
I-thermometer ye-infrared ilungele ukukala lokushisa komzimba nokukala okushisa okukhona. I-thermometer enjalo ilungele ukukala izinga lokushisa enganeni, ngoba akudingeki ukuthi liphazamise, futhi lokhu kuphinde kuqinisekisile ukulula kanye lula. Ukukalwa kuthatha nje imizuzwana embalwa, futhi umphumela uvele ngokushesha esibukweni. Idatha ngezilinganiso zokushisa zakamuva ziyagcinwa.
Okubi
Ukungathandeki okuyinhloko kwe-thermometer enjalo kuyizindleko eziphakeme. Iphutha ekulinganiseni idivaysi enjalo liphakeme impela. Ngomphumela onembe kakhudlwana, kuyadingeka ukwenza izilinganiso eziningi. Kubalulekile ukusebenzisa le divayisi kwezinye izingxenye zomzimba, njengebunzi, i-whisky nendlebe kuya emanzi.
Yimaphi amadivaysi avezwa angakhombisa umphumela onembe kakhulu?
Ukuze kutholakale ukuthi ngabe ama-thermometers anamuhla we-hermometer adlulele, kwenziwa isivivinyo. Elebhu, kufakwe isitsha samanzi, i-heater ekhethekile kanye nedivayisi eyayibhekele ukusatshalaliswa komfaniswano woketshezi futhi kugcinwe izinga lokushisa elibekiwe. Kwakungu-36.2 ° C.
Okokuhlola, ama-galin ialine ambalwa, athengwa ama-thermometers angu-elekthronikhi nakwemvelo. Ngokwemiphumela yesipiliyoni, kungashiwo ukuthi ama-thermometers we-mercury kanye ne-garin-standart thermometer anembe kakhulu. Futhi, ukufundwa kwama-thermometers we-elekthronikhi kwavela ukuthi kunembe ngokuphelele futhi kwasondelana nenani langempela lokushisa kwamanzi. Ama-thermometereter angenampilo awazange abhekane nalo msebenzi.
Ukuvumela ama-thermometer afanele ukwenze ukukhetha?
I-The Mercury thermometer ibhekwa njengendawo enembile kunazo zonke futhi yonke indawo yawo wonke ama-thermometer angenhla. Kepha akunakwenzeka ukuphuthelwa ukunaka ukuthi uma kusetshenziswa, ukuqaphela okukhulu kubalulekile. Kufanele igcinwe kuleli cala endaweni lapho izingane zizothola khona nakanjani.
Uma kungazelelwe kube nesimo lapho i-thermometer ye-Mercury yephulwe khona, kungcono ukufuna usizo kochwepheshe futhi ubone ukuthi amabhola we-mercury awakanakwa yini. Kubalulekile ukuthi ungakhohlwa ukuthi iMercury ayiphunga iphunga, futhi ngababili bayo abakwazi ukubonwa. I-thermometer ephukile ingadala ubuthi bayo bonke abahlali befulethi.
