Mitar TDS an daidaita masana’anta kuma a shirye take don amfani da ita daga cikin akwatin. Koyaya, bayan dogon amfani, karatun daga irin wannan na’urar na iya canzawa sosai. Wannan sananne ne musamman ga mitoci TDS masu arha.
Wanne maganin daidaitawa don zaɓar
Lokacin zabar maganin daidaitawa, yakamata ka fara karanta umarnin na’urarka. Yawancin mitoci na TDS masu ɗaukar nauyi ba su da ikon daidaitawa, kuma kawai mafita ga karatun da ba daidai ba shine maye gurbin mita da sabo.
Ana amfani da daidaitattun hanyoyin daidaitawa don daidaitawa. Waɗannan mafita ana yiwa alama alama akan fakiti tare da ƙimar gudanarwa (EC) a cikin mS / cm da ƙimar ppm masu dacewa da yanayin zafi daban-daban. Misalan mafita na daidaitawa:
Idan ba ku san wane bayani ake buƙata don na’urarku ba, muna ba da shawarar yin zaɓi 1000 ppm – Wannan shine mafi kyawun zaɓi na daidaitawa yayin aiki tare da mafita na hydroponic.
Yadda ake daidaita mitar TDS
Hanyar 1: Zuba kayan aiki a cikin maganin daidaitawa har zuwa matsakaicin matakin nutsewa. Girgiza mita TDS da sauƙi a cikin bayani don cire kumfa mai iska; Aljihun iska tsakanin na’urorin lantarki na iya tsoma baki tare da wutar lantarki da kuma karkatar da karatu. Jira 10-20 seconds don karatun ya daidaita.
Hanyar 2: Yi rikodin ƙimar TDS na maganin tare da kayan aiki kuma kwatanta tare da ƙimar tunani.
Hanyar 3: Idan karatun ya bambanta da fiye da 2%, daidaita kayan aiki bisa ga umarninsa (yawanci amfani da ƙaramin sukudireba ta hanyar saka ƙaramin raminsa a bayan kayan aikin).
- Juya dunƙule mai daidaitawa sannu a hankali kuma a hankali kusa da agogo don ƙara karantawa da kishiyar agogo don rage karatun.
- Tabbatar cewa screwdriver ya dace daidai da ramin dunƙule.
- Yi ƙoƙarin kiyaye kayan aiki a tsaye a cikin bayani.
Hanyar 4: Da zarar karatun mita ya kasance tsakanin 2%, daidaitawar yana tsayawa.
Hanyar 5: Cire na’urar daga maganin. Girgizawa don cire ɗigon ruwa waɗanda za su iya manne da na’urorin lantarki, haifar da gibin iska.
Hanyar 6: Kashe na’urar, jira minti daya, kuma sake kunna ta.
Hanyar 7: Saka TDS mita a cikin bayani kuma duba karatun. Idan har yanzu karatun yana nan daidai, daidaitawa ya cika. Idan ba haka ba, maimaita hanya.
Yadda za a yi maganin calibration
Kuna iya ƙirƙirar naku maganin daidaitawa don mita TDS mai ɗaukuwa. Wannan bayani ba zai ba ku 100% daidaito a cikin karatun ba, amma ba ma buƙatar madaidaicin madaidaici don kimanta adadin salts a cikin maganin ban ruwa.
Don shirya maganin calibration, muna buƙatar:
- sodium chloride (gishiri dafa abinci) – 1 gram
- distilled ruwa – 1 lita
- Kofin awo 1 lita
- Daidaitaccen ma’auni don nauyi mai sauƙi (misali kayan ado).
Auna gishiri gram 1 na busasshen gishiri a narkar da shi a cikin lita 1 na ruwa mai narkewa. Maganin daidaitawa yana shirye kuma yana faɗi mai zuwa: 2 mS/cm, O:
- 1000 ppm: don na’urori masu nauyin 0,5
- 1280 ppm: don na’urori masu nauyin 0,64
- 1400 ppm: don na’urori masu nauyin 0,7
Dubi tebur na juyawa don EC, TDS (mS / cm, ppm).
