Covportable hydrogen sulfide gas detectorfeem ntau ua haujlwm los ntawm cov pa sensor hauv nws. Cov txheej txheem tseem ceeb yog tias thaum lub sensor pom hydrogen sulfide, nws hloov nws cov concentration mus rau hauv lub ntsuas hluav taws xob teeb liab, uas tom qab ntawd ua tiav los ntawm lub hauv paus Circuit Court thiab tso tawm kom pom.
1.Electrochemical sensor
Lub hauv paus ntsiab lus ua haujlwm: Gas dhau los ntawm cov pa ua pa mus rau hauv lub sensor, qhov twg oxidation - txo cov tshuaj tiv thaiv tshwm sim ntawm cov electrodes thiab tam sim no tsim.
Nta: Siab rhiab heev, zoo precision, thiab tsawg zog noj. Tam sim no nws yog qhov tseem ceeb tshaj plaws daim ntawv thov technology.
Qhov tsis zoo: Lub sensor muaj lub neej luv luv (kwv yees li 2-3 xyoos) thiab tuaj yeem ua tsis tiav vim "kev lom" ntawm qhov siab heev.
Lub electrochemical sensor yog raws li lub hauv paus ntsiab lus ntawm REDOX cov tshuaj tiv thaiv. Thaum lub sijhawm kuaj pom, H2S nkag mus rau lub sensor thiab cuam tshuam nrog ions hauv electrolyte, ua rau REDOX cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no yuav ua rau muaj kev hloov pauv tam sim no, thiab lub sensor yuav txiav txim siab qhov concentration ntawm H2S los ntawm kev ntsuas qhov kev hloov tam sim no. Qhov zoo yog ceev thiab raug teb ceev, tab sis tsis tu ncua calibration yuav tsum tau los xyuas kom meej precision.
Lub electrochemical hydrogen sulfide detector, nrog nws cov rhiab heev thiab tsis muaj zog noj, yog ib qho ntawm feem ntau siv technologies tam sim no. Nws hloov cov roj concentration rau hauv cov teeb liab hluav taws xob los ntawm cov tshuaj tiv thaiv electrochemical rau kev ntsuas. Electrochemical H2S Gas Detector muaj qhov rhiab heev thiab tuaj yeem kuaj pom qhov tsis tshua muaj siab ntawm hydrogen sulfide. Nyob rau tib lub sij hawm, nws nta high precision, zoo repeatability thiab ruaj khov thiab txhim khu kev qha qhov tseem ceeb. Nws yog tshwj xeeb tshaj yog haum rau cov khoom siv portable uas yuav tsum tau ua haujlwm ntev thiab muaj lub sijhawm tos ntev. Vim yog siv cov electrolyte, nws lub neej feem ntau tsuas yog 2 mus rau 3 xyoo. Thiab nws yuav tsum tau calibrated tsis tu ncua txhua 3 mus rau 6 lub hlis; txwv tsis pub, qhov tseeb yuav poob qis.
2.Semiconductor sensor
Lub hauv paus ntsiab lus ua haujlwm: Muaj cov pa roj carbon monoxide-sensitive sheet heated to high temperature in. Thaum hydrogen sulfide los rau hauv kev sib cuag nrog nws, nws cov hluav taws xob conductivity yuav hloov raws li.
Nta: Tsis tshua muaj zog thiab ruaj khov, yoog raws qhov chaw hnyav, nrog rau kev pab cuam lub neej ntau dua 10 xyoo.
Qhov tsis zoo: qhov ntsuas qhov tseeb yog qhov tsawg thiab nws yooj yim cuam tshuam los ntawm lwm cov pa roj.
Semiconductor sensors ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev hloov pauv hloov. Thaum H2S nkag mus rau lub sensor, nws reacts nrog nto ntawm lub semiconductor tivthaiv, ua rau muaj kev hloov nyob rau hauv tsis kam. Lub sensor tuaj yeem ntsuas qhov kev hloov pauv no thiab hloov mus rau hauv lub teeb liab digital los sawv cev rau qhov concentration ntawm H2S. Qhov sensor no kuj pheej yig, tab sis nws cov lus teb ceev qeeb thiab nws yooj yim cuam tshuam los ntawm ib puag ncig yam xws li av noo thiab kub.
