Raws li lub hauv paus ntawm lub neej thiab qhov tseem ceeb ntawm kev lag luam, kev ntsuas qhov tseeb ntawm cov pa oxygen yog qhov tseem ceeb hauv ntau qhov chaw. Handheld oxygen analyzers, nrog rau lawv txoj kev txav mus los, ceev, thiab raug, tau dhau los ua cov cuab yeej tseem ceeb rau ntawm - qhov chaw sim. Tsab ntawv xov xwm no yuav tsom mus rau peb qhov xwm txheej tseem ceeb: ntsuas cov pa oxygen concentrator tso zis concentration, saib xyuas cov ntsiab lus oxygen hauv cov zaub mov ntim, thiab ntsuas cov pa oxygen concentration hauv huab cua puag ncig.
1. Oxygen Concentrator Concentration Analyzers:
Rau cov neeg siv xav tau kev kho cov pa hauv tsev, cov pa oxygen concentration tso tawm los ntawm cov pa oxygen concentrator ncaj qha cuam tshuam rau kev ua tau zoo thiab kev nyab xeeb. Ib qho khoom siv uas muaj cov pa tawm nominal ntawm 93% ± 3% tuaj yeem ua rau muaj kev ua haujlwm tsis zoo vim yog molecular sieve hnav, tivthaiv kev laus, lossis kev hloov pauv ntawm cov khoom siv hluav taws xob.
(1) Lub Luag Haujlwm:
Tus neeg siv txuas lub ntsuas mus rau lub qhov hluav taws xob oxygen concentrator ntawm lub raj txuas nyias, thiab lub ntsuas ntsuas pom cov pa oxygen concentration (%VOL) ntawm tus nqi ntws tam sim no hauv lub sijhawm.
(2).Technical nta:
High Range thiab High Accuracy: Tshwj xeeb rau kev ntsuas cov pa oxygen siab (feem ntau 70% -100%), nrog qhov tseeb ntawm ± 1% lossis siab dua, nws tuaj yeem kuaj pom txawm tias qhov tsawg tshaj plaws ntawm qhov concentration.
Tsawg Flow Resistance Design: Cov qauv tsim tshwj xeeb hauv cov pa hauv nruab nrog txo qis airflow tsis kam, kom ntseeg tau tias qhov ntsuas tsis cuam tshuam rau kev ua haujlwm ib txwm muaj thiab cov khoom tso tawm ntawm cov pa oxygen concentrator, yog li ua kom cov ntawv nyeem raug.
Tus neeg siv- Tus phooj ywg: Kev ua haujlwm yooj yim thiab cov txiaj ntsig zoo. Feem ntau nruab nrog lub suab qis - lub tswb nrov, nws cia li suab lub tswb thaum nyeem ntawv poob qis dua qhov kev nyab xeeb (piv txwv li, 82%), ua rau tus neeg siv ua haujlwm kho lossis hloov lub cuab yeej.
Peb lub tuam txhab CY-12C handheld oxygen analyzers thiab ZY-20C oxygen analyzers siv oxygen sensors tuaj ntawm UK. Lawv tuaj yeem saib xyuas cov pa oxygen concentration hauv cov pa oxygen concentrators raws li cov neeg siv khoom xav tau, nrog qhov tseeb ntawm ± 3% thiab ± 1%, feem.
2. Food Packaging Headspace Analyzer: Ib "Detective" rau kev khaws cia zoo
Hauv cov khoom noj thiab tshuaj lag luam, cov pa oxygen residual hauv ntim yog ib qho ntawm cov khoom tseem ceeb ntawm cov khoom spoilage thiab deterioration. Cov thev naus laus zis tseem ceeb ntawm kev hloov pauv huab cua ntim (MAP) thiab nitrogen- ntim ntim yog txo cov pa oxygen hauv ntim.
(1) Lub Luag Haujlwm:
Cov cuab yeej no ua haujlwm zoo li "microscopic detective," tshwj xeeb tshuaj xyuas cov roj muaj pes tsawg leeg hauv lub taub hau ntawm lub hnab ntim khoom (lub raj mis, cov kaus poom, thiab lwm yam). Nws yog txawm peem rau nrog ib tug zoo heev sampling koob. Thaum tho lub pob, lub micropump rho tawm cov roj me me, uas lub ntsuas ntsuas nrawm nrawm thiab qhia ncaj qha hauv %Vol lossis ppm.
Peb lub tuam txhab ZY-20C oxygen analyzer, ua ke nrog ib rab koob thiab syringe, tuaj yeem ntsuas cov pa oxygen hauv cov hnab ntim khoom. Kev kuaj pom ntau yog 0-100% vol, nrog kev daws teeb meem ntawm 0.01% vol ntawm qhov tsis tshua muaj siab.
(2).Technical nta:
Tsis yog -Kev kuaj kev puas tsuaj: Cov koob ntsuas tau zoo heev, tsim kom muaj qhov tsis txaus ntseeg thaum muab tso rau, uas tsis cuam tshuam rau lub ntim ntim lossis lub txee lub neej ntawm cov khoom seem, ua tiav qhov "tsawg kawg" lossis "tsis{1}} puas tsuaj".
High Sensitivity thiab Accuracy: Cov cuab yeej tuaj yeem kuaj xyuas cov pa oxygen tsawg heev hauv qab 0.1%, uas yog qhov tseem ceeb rau kev tswj cov khoom zoo thiab xyuas qhov kev sib khi ntawm cov kab ntim khoom.
Hygienic thiab Robust: Qhov kev sojntsuam feem ntau yog ua los ntawm cov hlau tsis muaj steel, ua kom yooj yim kom tsis muaj menyuam thiab tiv thaiv kev sib kis -. Cov cuab yeej siv lub cev muaj zog yog tsim rau kev tsim khoom hauv ib puag ncig.
Cov ntsiab lus: Nws yog ib feem tseem ceeb ntawm kev tswj xyuas qhov zoo, tiv thaiv cov khoom tshiab thiab kev nyab xeeb los ntawm qhov chaw ntawm cov kab ntau lawm.
3. Ambient Oxygen Detector: Ib "Sentinel" rau Kev Nyab Xeeb Lub Neej
Cov pa oxygen tsis zoo yog qhov muaj kev nyab xeeb loj hauv qhov chaw kaw (xws li lub nkoj cabins, cov kav dej hauv av, thiab cov fermentation tanks) lossis cov chaw uas muaj cov pa xau tuaj yeem tshwm sim (xws li cov chaw kuaj thiab cov chaw tso dej nitrogen). Concentrations tsawg dhau (<19.5%) can lead to asphyxiation due to lack of oxygen; those that are too high (>23.5%) nce qhov kev pheej hmoo ntawm kev tawg.
(1) Lub Luag Haujlwm:
Cov cuab yeej no ua haujlwm ua "tus neeg siab ncaj ncees" rau kev tswj hwm kev lag luam kev nyab xeeb thiab kev noj qab haus huv ntawm cov neeg ua haujlwm. Nws siv diffusion sampling kom tsis tu ncua saib xyuas qhov ambient oxygen concentration.
(2).Technical nta:
Tiag -Lub Sijhawm Saib Xyuas thiab Tswb: Muaj peev xwm ntawm 24-teev kev soj ntsuam tas li, nws muaj lub tswb ntsuas siab thiab qis qis. Yog tias cov concentrations ua txawv txav, lub tswb nrov ultra-siab decibel thiab lub teeb ci ntsa iab yuav tshwm sim tam sim, ceeb toom cov neeg ua haujlwm khiav tawm tam sim ntawd.
Intrinsically Safe Design: Ntau tus qauv kev tshaj lij muaj kev nyab xeeb (Ex) tau ntawv pov thawj, tso cai rau kev siv nyab xeeb hauv qhov chaw tawg thiab tawg yam tsis muaj qhov hluav taws kub.
Rugged thiab Durable: Cov plua plav tsis zoo, tsis muaj dej tsis zoo (IP ntsuas), thiab poob - tiv taus, nws tuaj yeem tiv taus ntau yam kev lag luam hnyav.
Cov ntaub ntawv Logging: Cov qauv Advanced txhawb cov ntaub ntawv logging kom yooj yim traceability thiab tsom xam.
Peb lub tuam txhab tsim portable oxygen concentration detectors thiab ruaj oxygen concentration detectors, uas yuav ntes tau cov pa concentration nyob rau hauv cov huab cua thiab xa lub tswb ceeb toom yog hais tias nws yog heev tsawg los yog siab dhau.
