Portable oxygen detectoryog cov cuab yeej kev nyab xeeb tshaj lij uas ntsuas cov pa oxygen hauv huab cua. Nws lub hom phiaj tseem ceeb yog ntsuas cov ntsiab lus ntawm cov pa oxygen los txiav txim seb puas muaj kev nyab xeeb nyob rau hauv ib puag ncig ntawm qhov chaw. Yog li ntawd, cov pa oxygen detectors tau siv dav hauv kev lag luam tshuaj, kev tshawb fawb kev tshawb fawb, qhov chaw kaw, kev kho mob, kev lag luam thee mine qhov thiab lwm yam xwm txheej.
Hauv kev lag luam kev lag luam, daim ntawv thov ntawm cov pa oxygen detectors yog ntau dua li kev saib xyuas kev nyab xeeb yooj yim. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, nws tau dhau los ua cov cuab yeej tseem ceeb rau kev txhim kho kev tsim khoom thiab kev ua kom zoo ntawm cov txheej txheem ntws. Piv txwv li, nyob rau hauv kev lag luam petrochemical, lub siab concentration ntawm oxygen ib puag ncig yuav ua rau muaj kev phom sij tawg, thaum lub concentration tsawg yuav ua rau tsis tiav combustion thiab cuam tshuam rau cov khoom zoo. Los ntawm kev saib xyuas cov pa oxygen kom raug, cov tuam txhab tuaj yeem kho cov xwm txheej tsim khoom raws sijhawm kom ntseeg tau tias muaj kev nyab xeeb ntau lawm thaum siv lub zog siv zog thiab txhim kho cov khoom zoo tsis tu ncua.
Tsis tas li ntawd, hauv kev ua zaub mov thiab ntim khoom, cov khoom siv oxygen kuj ua lub luag haujlwm tsis tuaj yeem hloov pauv. Cov ntsiab lus oxygen hauv cov zaub mov ncaj qha cuam tshuam rau nws lub txee lub neej thiab saj. Siv thev naus laus zis txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau oxygen
Hauv kev kho mob kev noj qab haus huv, cov cuab yeej ntsuas pa oxygen tau dhau los ua cov cuab yeej siv hauv cov tsev kho mob hnyav, cov chav tsev pa oxygen hyperbaric thiab lwm qhov chaw. Rau cov neeg mob uas xav tau cov pa oxygen tas mus li, kev saib xyuas lub sijhawm tiag tiag ntawm oxygen saturation hauv lawv cov ntshav yog qhov tseem ceeb rau kev kho cov phiaj xwm kho mob thiab tiv thaiv cov teeb meem. Nyob rau tib lub sijhawm, nrog kev nrov ntawm cov cuab yeej kho mob hauv tsev, cov cuab yeej siv pa oxygen tau maj mam nkag mus rau tib neeg lub tsev, muab cov neeg mob uas muaj kab mob ua pa ntev nrog txoj kev tswj hwm kev noj qab haus huv yooj yim dua thiab nyab xeeb.
1. Muaj kev ruaj ntseg ntau lawm: Nyob rau hauv cov txheej txheem ntawm industrial ntau lawm xws li tshuaj, roj av, thiab natural gas, flammable thiab explosive gases los yog hypoxic ib puag ncig tej zaum yuav generated. Kev siv cov pa oxygen detectors tuaj yeem saib xyuas cov pa oxygen hauv qhov chaw ua haujlwm hauv lub sijhawm tiag tiag kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
2. Kev tua hluav taws thiab cawm: Thaum muaj hluav taws kub, cov pa taws thiab cov pa phem tuaj yeem ua rau qhov chaw tsis muaj oxygen. Cov neeg tua hluav taws uas nqa cov pa oxygen tuaj yeem pab lawv ntsuas cov pa oxygen ntawm qhov chaw thiab zam kev phom sij vim hypoxia.
3. Kev ua haujlwm hauv mines: cov pa phem xws li methane thiab carbon monoxide tuaj yeem muaj nyob hauv cov mines, thiab tej zaum yuav muaj qhov chaw hypoxic tob hauv cov mines. Cov neeg ua haujlwm miner tuaj yeem siv cov khoom siv oxygen los kuaj xyuas cov kev phom sij no nyob rau lub sijhawm thiab ntsuas kev nyab xeeb rau lawv tus kheej.
4. Kev tshawb fawb hauv chav kuaj: Thaum ua cov kev sim tshuaj, qee cov tshuaj yuav siv tau cov pa oxygen lossis tsim cov pa phem. Siv cov pa oxygen detectors los tiv thaiv kev nyab xeeb ntawm cov neeg sim.
5. Kev ua haujlwm siab: Thaum ua haujlwm ntawm qhov siab siab, cov pa oxygen yuav maj mam txo qis vim qhov nce siab. Siv lub ntsuas pa oxygen tuaj yeem pab cov neeg ua haujlwm nkag siab txog qib oxygen ntawm ib puag ncig tam sim no thiab xyuas kom lawv txoj kev noj qab haus huv yuav tsis cuam tshuam los ntawm kev tsis muaj oxygen.
