High-precision CJ them nyiaj
Qhov kev ruaj ntseg thiab qhov tseeb ntawm CJ qhov kub thiab txias ua lub luag haujlwm tseem ceeb hauv kev ntsuas ntawm cov thermocouples siab.Feem ntau siv high-precision digital ntsuas yuav tsum tau ua ke nrog cov khoom tshwj xeeb CJ them nyiaj rau kev ntsuas thermocouple.Lub siab-precision CJ them nyiaj module yog kev koom ua ke hauv PR293 series cov ntsuas kub, yog li CJ yuam kev ntawm cov channel siv uas zoo dua 0.15 ℃ yam tsis muaj lwm yam khoom siv tuaj yeem pom tau.
Kev nplua nuj kub metrology ua haujlwm
PR291 / PR293 series cov ntsuas kub yog cov ntsuas ntsuas tshwj xeeb uas tsim los rau kev lag luam kub ntsuas ntsuas.Muaj peb hom kev ua haujlwm ntawm kev nrhiav tau, ib leeg-channel taug qab, thiab ntsuas qhov sib txawv ntawm qhov kub thiab txias, ntawm qhov ntsuas qhov sib txawv ntawm qhov ntsuas kub tuaj yeem txheeb xyuas qhov ntsuas kub tsis sib xws ntawm txhua yam khoom siv ntsuas kub tas li.
Piv nrog rau cov tsoos digital multimeter, 30mV ntau yam tshwj xeeb rau kev ntsuas S-hom thermocouples thiab 400Ω ntau rau PT100 platinum kuj ntsuas tau ntxiv.Thiab nrog cov kev pab cuam hloov dua siab tshiab rau ntau lub ntsuas kub, ntau yam ntawm cov ntsuas ntsuas (xws li tus qauv thermocouples, tus qauv platinum tsis kam ntsuas kub, muaj platinum tsis kam ntsuas kub thiab ua haujlwm thermocouples) tuaj yeem txhawb nqa, thiab cov ntaub ntawv pov thawj lossis cov ntaub ntawv kho tuaj yeem raug xa mus rau kab. qhov ntsuas kub ntawm qhov ntsuas ntsuas.
Cov ntaub ntawv tsom xam muaj nuj nqi
Ntxiv nrog rau ntau yam kev sim cov ntaub ntawv, nkhaus thiab cov ntaub ntawv khaws cia tuaj yeem tso tawm, cov ntaub ntawv ntawm lub sijhawm ntau tshaj / tsawg / nruab nrab tus nqi, ntau yam ntawm cov ntaub ntawv ntsuas kub yuav raug xam, thiab cov ntaub ntawv siab tshaj plaws thiab qhov tsawg kawg nkaus tuaj yeem raug cim los pab txhawb kev tshawb xyuas cov ntaub ntawv. ntawm qhov chaw xeem.
Portable tsim
High-precision digital meters feem ntau siv nyob rau hauv lub chaw soj nstuam yog feem ntau loj thiab tsis portable.Hauv qhov sib piv, PR291 / PR293 series cov ntsuas kub yog qhov me me hauv ntim thiab qhov hnyav, uas yooj yim rau kev ntsuas kub siab hauv ntau qhov chaw nyob.Tsis tas li ntawd, tus qauv tsim ntawm lub peev xwm loj loj lithium roj teeb kuj ua rau kev ua haujlwm yooj yim dua.
