Njira zamakono zopangira, kuyambira pakuwunika kwazinthu zopangira, kuwongolera njira zopangira mpaka kuwunika komaliza ndi kuwunika kwazinthu, sizingasiyanitsidwe ndi zida ndi mita zosiyanasiyana.Pofuna kuonetsetsa kupanga apamwamba, m'pofunika nthawi zonse ntchito zosiyanasiyanampweya wabwinokutsimikizira kapena kuwongolera zida zake ndi mita, makamaka pambuyo pakugwiritsa ntchito nthawi yayitali ndikukonzanso zida zapaintaneti ndi mita, ndikofunikira kugwiritsa ntchito mipweya yokhazikika kuti muwongolere sikelo.Mitundu yosiyanasiyana ya ma calibration standard gasi ndi awa:

| Methane mu mpweya | 10 × 106, 1% | Chromatograph ya gasi | |
| Methane mu haidrojeni | 1% | ||
| Methane mu nayitrogeni | 100 × 106, 1% | ||
| Carbon dioxide, propane | 10 × 106, 1% | ||
| Mpweya wa carbon monoxide mu nayitrogeni | carbon monoxide | 0.5% ~ 5% | Automobile emission analyzer |
| mpweya woipa | 0-14% | ||
| propane | 800 × 106-1.2% | ||
| Sulfure hexafluoride mu nayitrogeni | 0 ~ 6000 × 10-6 | Sulfur hexafluoride leak detector, sulfure hexafluoride analyzer | |
| Nitric oxide mu nayitrogeni | 0 ~ 1000 × 10-6 | Automobile emission analyzer, chemiluminescence nitrogen oxide analyzer | |
| Oxygen mu nayitrogeni | 10 × 106-21% | Oxygen analyzer | |
| Hydrogen sulfide mu nayitrogeni | 0-20% | Hydrogen sulfide gas analyzer | |
| Isobutane mumlengalenga | 0-1.2% | Chida choyezera gasi ndi kupereka malipoti | |

| Ammonia mu nayitrogeni | 0-30% | Ammonia analyzer | |
| Mowa mumlengalenga | 0 ~ 100 × 10-6 | Alamu ya mowa | |
Ntchito yampweya wokhazikika
(1) Khazikitsani kutsata kwa miyeso.Zida zowonetsera mpweya zimakhala ndi homogeneity yabwino komanso kukhazikika, zimatha kusunga mankhwala ndi makhalidwe a zinthuzo, ndikusintha makhalidwe awo m'malo ndi nthawi zosiyanasiyana.Chifukwa chake, kuwunika kwa kuyeza kumatha kupezedwa pogwiritsa ntchito gasi wokhazikika pazotsatira zosiyanasiyana zoyezera.
(2) Limbikitsani chitukuko cha teknoloji yoyezera ndi kuyang'anira khalidwe.Mpweya wokhazikika umagwira ntchito yofunikira pakuwonetsetsa kuti zinthu zili bwino komanso zotsatira zowunika, ndikuwonetsetsa kuti sayansi, ulamuliro ndi kupanda tsankho kwa kuyang'anira luso.Chizindikiritso chamtundu wa zida zatsopano, chiphaso cha metrological cha mabungwe owunikira bwino, kuvomerezeka kwa labotale, komanso kupanga, kutsimikizira ndi kukhazikitsidwa kwa miyezo yamafuta amtundu wa dziko ndi mafakitale sikungasiyanitsidwe ndi mpweya wokhazikika.
(3) Tumizani kuchuluka kwa mtengo.Gasi wambandi njira yosinthira kuchuluka kwa kuchuluka ndikupeza zotsatira zofananira.Miyezo yamagawo oyambira a International System of Units imasamutsidwa ku kuyeza kwenikweni kudzera mu mpweya wokhazikika wamagulu osiyanasiyana kuti zitsimikizire kulondola kwa zotsatira za kuyeza.
(4) Onetsetsani zotsatira zolondola kwambiri komanso zosasinthasintha.Mpweya wokhazikika ungagwiritsidwe ntchito poyesa kapena kutsimikizira mtundu wa kuyeza kwake ndi miyeso yosiyana siyana, kuti muwonetsetse kuti kugwirizana kwa miyeso kumabweretsa nthawi ndi malo osiyanasiyana.
