Umkhiqizo Omusha: I-PR721/PR722 Series Precision Digital Thermometer

I-thermometer yedijithali enembile yochungechunge lwe-PR721 isebenzisa inzwa ehlakaniphile enesakhiwo sokukhiya, engashintshwa ngezinzwa zemininingwane ehlukene ukuze kuhlangatshezwane nezidingo ezahlukene zokulinganisa izinga lokushisa. Izinhlobo zezinzwa ezisekelwayo zifaka ukumelana neplatinum ene-wire-wound, ukumelana neplatinum enefilimu encane, izinzwa ze-thermocouple kanye nomswakama, ezingabona ngokuzenzakalelayo futhi zilayishe uhlobo, ububanzi bokushisa kanye nenani lokulungisa lenzwa exhunyiwe. I-thermometer yenziwe nge-aluminium alloy iyonke, enesigaba sokuvikela se-IP64, esingasetshenziswa ngokuthembekile ezindaweni ezinzima.

Izici Zobuchwepheshe

1. Inzwa ehlakaniphile, ububanzi bokushisa buhlanganisa -200~1300℃. Isebenzisa izingxenye zokukhiya ezingamelani nokushisa okuphezulu, umninikhaya angalayisha ngokuzenzakalelayo uhlobo lwenzwa yamanje, ububanzi bokushisa kanye nenani lokulungisa ngemva kokuxhuma kunzwa ehlakaniphile, okuthuthukisa ukunemba kokulandelela izinga lokushisa, kanye nokusebenza kahle komsebenzi.

2. Ukushisa okuphansi, okuphakathi kuka-5 ~ 50℃, ukunemba kokulinganisa kukagesi kungcono kuno-0.01, futhiisixazululo singu-0.001℃, esingahlangabezana nezidingo zokulinganisa izinga lokushisa ezijwayelekile.

3.Kumodi yediski ye-U, ukushaja noma ukudluliswa kwedatha kungenziwa nge-interface ye-Micro USB, elula ukuhlela idatha yokuhlola ngokushesha.

4. Umsebenzi wokuzwa amandla adonsela phansi, usekela ukupheqa isikrini ngokuzenzakalela, kanye nesipiliyoni sokufunda esifanele singatholakala ngokusibeka kwesobunxele noma kwesokudla.

5. Sekela ukuxhumana kwe-Bluetooth noma i-ZigBee, ungasebenzisa i-Panran Smart Measurement APP ukuvumelanisa idatha noma ukwandisa ezinye izinhlelo zokusebenza.

6. Isigaba sokuvikela i-IP64 sokusetshenziswa okuthembekile ezindaweni ezinzima.

7. Ukusetshenziswa kwamandla okuphansi kakhulu, ibhethri le-lithium elishajekayo elakhelwe ngaphakathi, umsebenzi oqhubekayo amahora angaphezu kwe-130.

Eminye Imisebenzi

1. Voukulinganisa i-latility ngezikhathi ezibekiwe

2. Ukulinganisa izinga lokushisa elihlobene

3.Ukubala inani eliphakeme, elincane kanye nesilinganiso

4. Ukuguqulwa kwenani likagesi/inani lokushisa

5. Ukuhlela inani lokulungiswa kwenzwa

6. I-alamu yokushisa okungaphezu kokushisa

7. Iwashi lesikhathi sangempela elinokunemba okuphezulu elakhelwe ngaphakathi

8. Ongakukhetha ℃, ℉, K
