GC-7890 Gas chromatograph siv lub tshuab tswj hwm microcomputer thiab Suav teb lub vijtsam loj, qhov tsos zoo nkauj dua thiab du. Cov yuam sij keyboard tshiab tsim tau yooj yim thiab ceev, thiab cov voj voog yog cov khoom xa tuaj, yog li cov cuab yeej ua haujlwm ruaj khov thiab txhim khu kev qha.
Ⅰ. Kev sib koom ua ke ntawm lub voj voog siab, kev ua haujlwm siab, ntau lub luag haujlwm
1. Kev ua haujlwm tseem ceeb ntawm lub khoos phis tawj microcomputer, 5.7 nti (320 * 240) LCD loj hauv Suav thiab Askiv, Suav thiab lus Askiv zaub tuaj yeem hloov pauv tau yooj yim, kom ua tau raws li qhov xav tau ntawm ntau pawg neeg, kev sib tham ntawm tib neeg thiab tshuab, yooj yim rau kev khiav lag luam.
2. Lub tshuab microcomputer tswj tau lub tshuab ntes hluav taws hydrogen kom ua tiav qhov kev ua haujlwm tsis siv neeg, ntse dua. Lub voj voog hluav taws xob digital tshiab, kev tswj hwm qhov tseeb siab, kev ua haujlwm ruaj khov thiab txhim khu kev qha, txog li 0.01 ℃ kev tswj qhov kub thiab txias.
3. Kev tiv thaiv roj, tiv thaiv lub kem thiab lub pas dej ua ke thermal conductivity, lub tshuab ntes hluav taws xob.
Nws muaj lub luag haujlwm ntawm kev kuaj mob tus kheej thaum pib, uas ua rau cov neeg siv paub sai sai qhov ua rau thiab qhov chaw ntawm qhov tsis ua haujlwm ntawm cov cuab yeej, muaj nuj nqi stopwatch (ntsuas kev ntws yooj yim), lub zog tsis ua haujlwm khaws cia thiab tiv thaiv, muaj nuj nqi tiv thaiv kev hloov pauv hluav taws xob, kev sib txuas lus cov ntaub ntawv hauv network thiab kev tswj chaw taws teeb. Lub luag haujlwm tiv thaiv kub dhau yog lav.
Cov cuab yeej tsis puas tsuaj thiab muaj lub cim xeeb ntaub ntawv uas tsis tas yuav rov pib dua txhua zaus.
Ⅱ.Kev tsim tshwj xeeb ntawm kev txhaj tshuaj, tuaj yeem txo qis qhov kev txwv tsis pub dhau
1. Kev tsim qhov chaw txhaj tshuaj tshwj xeeb los daws qhov kev sib txawv ntawm kev txhaj tshuaj; Lub luag haujlwm them nyiaj ob chav kem tsis yog tsuas yog daws qhov kev hloov pauv ntawm kab pib los ntawm qhov kub thiab txias, tab sis kuj tseem rho tawm qhov cuam tshuam ntawm lub suab nrov tom qab kom tau txais qhov txwv qis dua.
2. Nrog rau kem ntim, capillary shunt / non-shunt txhaj tshuaj system (nrog diaphragm ntxuav muaj nuj nqi)
3. Xaiv tau lub tshuab txhaj roj rau txoj kev uas siv lub tshuab tsis siv neeg/phau ntawv, lub tshuab txhaj tshuaj headspace, lub tshuab txhaj tshuaj thermal resolution, lub tshuab hloov methane, lub tshuab txhaj tshuaj tsis siv neeg.
Ⅲ, Kub programmed, qhov cub kom raug tswj kub, ruaj khov sai
1. Yim-txheej txheem kub linear programmed, tom qab lub qhov rooj siv photoelectric switch contactless tsim, txhim khu kev qha thiab ruaj khov, ntse tom qab lub qhov rooj system stepless variable cua ntim, luv qhov kev pab cuam tom qab nce / poob ntawm lub detector system ruaj khov lub sijhawm sib npaug, tiag tiag paub txog qhov ze chav kub ua haujlwm, kub tswj qhov tseeb ntawm ± 0.01 ℃, ua tau raws li qhov xav tau ntawm ntau yam kev tshuaj xyuas.
2. Lub thawv loj heev, lub qhov rooj tom qab ntse tsis muaj zog hloov pauv cua ntim rau hauv thiab tawm, ua kom luv qhov kev pab cuam tom qab tsa / txias lub tshuab ntes lub sijhawm ruaj khov; Lub tshuab cua sov: qhov kub thiab txias + 5 ℃ ~ 420 ℃.
