Mā te tohu taiaho i runga i te PE ka tangohia tika te rauemi mata, ka whakakorea ngā toenga matū me te poke, ka whakarite i te haumaru me te hoahoa taiao. Ka mahi tēnei tikanga ki ngā mata pounamu piko, ka noho mārama ngā rā whakaputa, ngā tau puranga, me ngā waehere pae i te wā e kawe ana me te whakamahi, ka whakarei ake i te whai i ngā hua me te mōhio ki te waitohu.

Ka whakamahia e te tohu reera muka i runga i ngā paipa kirihou HTTP te whakamahana reera ā-rohe hei hanga i tētahi pānga pahuka iti, ka hangaia he tohu hina-mā mārama ki runga i ngā paipa kikorangi-hina. Ka arotahihia e tēnei tikanga ngā hihi reera kaha-nui ki runga i te mata kirihou, ka whakaoho i tētahi tauhohenga pahuka e puta ai he tohu pakari, mārama hoki.

Hei tukanga kore-pā, kāore e hiahiatia he taonga pau mō te tohu taiaho, ā, ka whakakorea te parahanga matū, ka whakarite i te haumaru o te taiao. He tino ātete ngā tohu ki te kakahu, ka mau tonu ki ngā āhuatanga o waho me te koroheketanga, ka pai ake ai te whai i ngā puranga me te whakahaere tautuhi mō ngā paipa wai.

Mā te tohu taiaho UV i runga i ngā paipa kirihou PE pango ka whakamahia te kaupapa whakarerekētanga tae hei hanga tohu hina mārama. Ka whakarerekē tika te taiaho i te hanganga ngota o te rauemi, ka hangaia he tohu pakari, he rerekē te tae, me te kore he mea pau, he parahanga matū rānei, kia mau ai te haumaru o te taiao.

Mā tēnei tikanga tohu kore-pā ka puta he hua mārama, he ātete ki te kakahu, ā, he ātete hoki ki te memeha, ka mau tonu te māramatanga ahakoa i roto i ngā taiao uaua me te whakamahinga roa. Ka tautoko pono i te whai i ngā hua me te tautuhi waitohu.

Mā te tohu taiaho UV i runga i ngā panera pana PC mā e ātete ana ki te pāmahana teitei ka hangaia he tuhinga hina ngawari me te tino tika. Ka whakatikatika tika te taiaho i te pūngao kia puta ai he huringa tae iti me te kore e kino te hanganga rauemi. Kei roto i ngā tohu te ingoa waitohu, ngā taipitopito kamupene, me ngā whakatakotoranga hua, kia mārama ai, kia roa ai, kia ātete ai hoki ki te kakahu.

He pai mō te taiao tēnei tukanga kore-parahanga, kore-paoa, ā, he ātete ki te pā me te horoi pinepine, e pupuri ana i te ataahua o te panera. He pai mō te whakamahi i te kāinga, e whakarei ake ana i te waitohu hua me te whakaatu i te ahua kounga teitei, e tuku ana i te mahi me te ataahua o te tirohanga.

Ka whakamahia te tohu taiaho UV hei tā i ngā waitohu waitohu ki ngā hononga kirihou BPT. E mōhiotia ana mō tōna ātete wera pai, tōna roa o te mau o ngā matū, me tōna kaha miihini teitei, e whakamahia whānuitia ana te BPT i roto i ngā taiao kaha me ngā taiao uaua. Nā tōna matotoru me tōna mata maeneene e tino pakari ai, e ātete ana hoki ki te kakahu.

Heoi, nā te kaha me te ātete wera o te BPT ka uaua te tohu i te laser, me te whakahaere pūngao tika kia mārama, kia roa hoki ngā hua. Ka hangaia e te tohu laser UV ngā tohu rerekētanga teitei ki runga i ngā mata BPT me te pupuri tonu i te kounga o ngā rauemi, ka waiho hei otinga pai mō te waitohu me te tautuhi.

Ko ngā tohu taringa kararehe kōwhai ka tohua ki te taiaho UV, ka puta he tohu hina-mā tuturu, tae atu ki ngā waehere QR, ngā waehere pae, me ngā waehere tau. Mā tēnei tikanga ka roa te mau, ka ātete ki te memeha, ki te pakaru rānei i te rā, te ua, me te pāmahana tiketike.

Mā ngā waehere QR me ngā paewaehere ka taea te aroturuki tere i ngā kararehe me te whakahaere matihiko, ka taea ai te uru atu ki ngā tuhinga tuakiri, hauora, me te werohanga. Mā te matawai i te waehere QR, ka taea e ngā kaiwhakahaere pāmu te tiki tere i ngā raraunga e tika ana, ka whakapai ake i te whai huatanga me te mōhiohio i roto i te mahi ahuwhenua kararehe.

Mā te tohu taiaho UV i runga i ngā rama LED āhua kōpae PVC ka hangaia he tohu waitohu hina ki runga i te mata mā mā te pānga whakarerekētanga tae. Mā te kaha taiaho e whakahaeretia tika ana ka puta he rerekētanga ngawari o te mata, ka hangaia he tohu rerekē teitei, he roa te mau.

Mā tēnei tohu kore-pā ka whakarei ake i te ahua o te waitohu, ka tāpirihia hoki ngā āhuatanga ārai-tīpako, kia pono ai te hua. Kāore he mea e pau ana, he matū rānei e hiahiatia ana, he pai mō te taiao, he haumaru hoki. Mā ngā tohu pakari, ātete-me-ngāwari e whakarato he whakaaturanga waitohu ngaio, pono hoki.
