YY-3C PH Imitha
Isetshenziselwa ukuhlola i-pH yamamaski ahlukahlukene.
I-GB/T 32610-2016
I-GB/T 7573-2009
1. Izinga lezinsimbi: 0.01 izinga
2.Ibanga lokulinganisa: pH 0.00 ~ 14.00pH; 0 ~ + 1400 mv
3. Ukulungiswa: 0.01pH,1mV,0.1℃
4. Ibanga lesinxephezelo sezinga lokushisa: 0 ~ 60℃
5. Iphutha eliyisisekelo leyunithi ye-elekthronikhi: pH±0.05pH,mV±1% (FS)
6. Iphutha eliyisisekelo lensimbi: ±0.01pH
7. Iyunithi ye-electronic input yamanje: akukho ngaphezu kwe-1×10-11A
8. I-impedance yeyunithi ye-elekthronikhi: hhayi ngaphansi kuka-3×1011Ω
9. Iphutha lokuphindaphinda kweyunithi ye-elekthronikhi: pH 0.05pH,mV,5mV
10. Iphutha lokuphindaphinda kwensimbi: hhayi ngaphezu kuka-0.05pH
11. Ukuzinza kweyunithi ye-elekthronikhi: ±0.05pH±1 igama /3h
12. Ubukhulu (L×W×H) : 220mm×160mm×265mm
13. Isisindo: cishe 0.3kg
14. Izimo zesevisi ezijwayelekile:
A) Izinga lokushisa le-ambient :(5 ~ 50) ℃;
B) Umswakama ohlobene :≤85%;
C) Ukunikezwa kwamandla: DC6V; D) Akukho ukudlidliza okubalulekile;
E) Akukho ukuphazamiseka kwamagnetic kwangaphandle ngaphandle kwendawo kazibuthe yomhlaba.
1. Sika isampula elihloliwe libe yizicucu ezintathu, i-2g ngayinye, lapho iphukile kakhulu iba ngcono;
2. Faka eyodwa yawo ebhikeni elingunxantathu elingu-500mL bese ufaka amanzi acwecwe angu-100mL ukuze ucwile ngokugcwele;
3. Oscillation ihora elilodwa;
4. Thatha u-50mL we-extract bese uyikala ngethuluzi;
5. Bala inani elimaphakathi lezilinganiso ezimbili zokugcina njengomphumela wokugcina.
