Na farko: ƙudurin infrared. Ƙaddamar da ƙayyadaddun ƙayyadaddun hoton zafi - ƙuduri mafi girma yana nufin ƙarin cikakkun bayanai a cikin hoton zafi. Ƙididdigar gama gari sun haɗa da 160 × 120 (kimanin pixels 20,000), 320 × 240 (kimanin pixels 77,000), da 640 × 480 (kimanin pixels 310,000). 160 × 120 ƙuduri ya dace da saurin dubawa da dubawa gabaɗaya; 320 × 240 shine madaidaicin zabi don yawancin aikace-aikacen masana'antu; 640×480 ya dace da kyakkyawan bincike, kamar gano bambance-bambancen zafin jiki na minti daya a cikin kayan lantarki.
Na biyu: NETD (Bambancin Matsakaicin Haɗuwa da Surutu). NETD tana wakiltar mafi ƙarancin bambancin yanayin zafi da kyamarar zafi za ta iya warwarewa, wanda aka auna a mK (millikelvin). Ƙananan NETD yana nufin mafi girman hankali ga ƙananan bambance-bambancen zafin jiki.

Na uku: kewayon zafin jiki. Aikace-aikace daban-daban suna buƙatar jeri daban-daban. Binciken kayan aikin lantarki yawanci yana buƙatar -20 ° C zuwa + 150 ° C; Binciken wutar lantarki na masana'antu yana buƙatar 0 ° C zuwa + 1000 ° C ko mafi girma; Binciken asarar zafi na ginin yana buƙatar -20 ° C zuwa + 60 ° C. Jerin PK63 kyamarar zafi na hannu yana goyan bayan -55°C zuwa +1580°C, yana rufe yawancin aikace-aikace daga binciken gini zuwa ƙarfe.
Layin samfurin hoto na thermal wanda ke goyan bayan FangService ya haɗa da samfura uku waɗanda ke rufe cikakken bakan daga matakin shigarwa zuwa ƙwararru. Fahimtar bambance-bambance shine mataki na ƙarshe na zaɓi.
PK61 kyamarar zafi ce ta aljihu wanda aka ƙera don dubawa cikin sauri. Babban fa'idarsa shine ɗaukar hoto - ƙananan isa don dacewa a cikin aljihu, haske isa ya ɗauka duk rana. Aiki mai sauƙi ne: kunnawa, manufa, karanta - matakai uku cikakke. Ya dace da: duban zafin jiki na yau da kullun na akwatunan lantarki, kimantawa da sauri na tsarin HVAC, da farkon wuri na leaks na ginin. PK61 yana da matsakaicin ƙudurin infrared da NETD a kusa da 50mK, yana biyan buƙatun dubawa gabaɗaya.
PK62 wani ma'aunin zafi da sanyio na infrared (IR gun) wanda aka ƙera don auna zafin ma'ana. Ba kamar kyamarar zafi ba, ma'aunin zafin jiki na infrared yana auna zafin jiki a wuri guda - manufa, latsa, kuma lambar zazzabi tana bayyana akan allon. Fa'idodin PK62 sune madaidaicin madaidaici (yawanci ± 1°C zuwa ±2°C), amsa mai sauri (yawanci ƙarƙashin 1 seconds), kuma ɗan ƙaramin farashi. Ya dace da: madaidaicin ma'aunin zafin jiki mai lamba ɗaya, kamar zafin jiki mai ɗaukar mota, zafin saman bututu, da sarrafa zafin jiki a cikin sarrafa abinci.
PK63 kyamarar zafi ce mai girman ƙudurin hannu, ƙirar ƙwararru a cikin layin samfur. Yana da mafi girman ƙudurin infrared, ƙananan NETD, da kewayon zafin jiki mai faɗi.
