utu karawhiti ph
Ko te utu o te mētara pH irirangi he mea whakatau nui mō ngā whare wananga, ngā umanga, me ngā whare rangahau e kimi ana i ngā whakaeke whirihau mō te ine i te pH. Kua wātea ēnei taputapu matatau, i runga i ngā tau utu rereke mai i te $50 ki te $500, ka tuku i ngā ine pH tāwhai hauāne mā te whakamahi i te irirangi hauāne. Ko ngā mētara pH hou he whakakapi mata kiriata, he whakarāwekenga wāhi noho ake i te āhuatanga o te ākau, me ngā whaitua kalikātia, e whakarite ai i ngā pānga tāwhai hauāne i runga i ngā whakamahinga rereke. Ko te utu e rerekē ana mā te whai whakaaro ki te tika o te ine, te wehenga (he tata ki te 0.01-0.001 ngā wae tātai pH), ngā āhua atu pērā i ngā whaitua pānui raraunga, me te kounga o te hanga. Ko ngā tauira tuatahi e tika ana mō te whakamātau wai māmā ka tīmata i te $50-100, i te wā e hokona ai ngā taputapu kairangi hauāne me te roa atu me ngā āhua hou ake i ngā utu teitei ake o te $200-500. Ko te kounga irirangi te nuinga e āwhina ai i te utu, me ngā irirangi motuhake mō ngā whakamahinga motuhake e utu nui ake ana engari ka tuku i te roa me te tika ake. Kei te maha o ngā tauira ngā āhua pērā i te arataki pūmahara ake, ngā tohu mō te kaimahi, me ngā kaiwhakauru ākau, e whakapai ai i ēnei taputapu hei taputapu whai wāhi mō te whakahaere kounga, te rangahau, me ngā whakaeke umanga.
