Yeyiphi eyona mitha ye-pH echasene nokuqhuma kwemizi-mveliso engcono kakhulu?

Iimpawu eziphambili kunye neenzuzo‌

1.‌Uyilo Olukhuselekileyo Nolungenaziqhushumbisi‌

• Iyahambelana nemigangatho ye-GB3836.1-2010 kunye ne-GB3836.4-2010, ilinganisweEx ia IIC T4Ga‌.
• Ifanelekile kwiindawo ezinobungozi ezinamaqondo obushushu aphantsi ukusuka kwi-20 °C ukuya kuma-55 °C‌.

2.‌Uluhlu Lokulinganisa Oluphezulu Nolubanzi‌

• ‌i-pH:‌ 0.00–14.00 (± 0.05 ukuchaneka kwe-pH)
• ‌I-ORP:-2000 mV ukuya kwi-2000 mV (ukuchaneka kwe-±1 mV)
• ‌Ubushushu:‌Pt1000: 0.0 °C–130.0 °C / NTC10k: -30.0 °C–100.0 °C (ukuchaneka kwe-±0.5 °C)

3.‌Imveliso yeengcingo ezimbini ezingama-4–20 mA kunye nokusetyenziswa kwamandla aphantsi‌

• Isiphumo se-current-loop esisodwa se-4–20 mA sokudibanisa ngaphandle komthungo neenkqubo ze-PLC, i-DCS, okanye ze-SCADA.
• Ukusetyenziswa kwamandla aphantsi kakhulu (0.66 W) kuxhasa ukusebenza kwexesha elide nokuba kufakwe kude okanye kufakwe amandla abuthathaka.

4.‌Ulwakhiwo Oluqinileyo kunye Nokusetyenziswa Okulula‌

• Indlu ye-aluminium eyenziwe nge-die-cast eneIP65ukhuseleko ekungeneni kothuli namanzi.
• Ubukhulu obuncinci (144 mm × 144 mm × 147 mm) kunye neendlela ezahlukeneyo zokufakela: ukufakwa okufakwe ngaphakathi, ukufakwa kwimibhobho, udonga olusecaleni, ukufakwa kwe-top-flange, ukuntywiliselwa, kunye nokufakelwa kwe-flow-through.

5.‌Ukusebenza okulula ukuSebenzisa kunye noLungiso oluHlakaniphileyo‌

• Isibonisi se-LCD esicacileyo esinokuhamba ngamaqhosha amahlanu ukuze kulungiselelwe ngokukhawuleza, kulinganiswe, kwaye kuhlolwe.
• Iindlela ezininzi zokulinganisa: ngesandla, i-auto-cal enamachaphaza amabini, i-auto-cal enamachaphaza amathathu, kunye namaqela e-buffer anokulungiswa (imigangatho ye-JJG/NIST).
• Isalathisi semeko ye-electrode ngexesha langempela (egqwesileyo/eqhelekileyo/embi) kunye nokulungiswa kwendlela yokulungisa ukuze kuphume imveliso ezinzileyo ngexesha lokulungiswa kwesensor.
