1.1 Bayani game da samfurin

S-SCPH yana daya daga cikin masu nazarin sinadarai masu hankali na kan layi da kamfaninmu ya haɓaka, daidaitawa da muhalli mai ƙarfi, nuni mai kyau, sauƙin aiki da kyakkyawan aikin gwaji ya sa ya kasance mai inganci don auna ƙimar pH da zafin jiki na mafita daidai. Ana iya amfani da shi sosai don ci gaba da sa ido kan darajar pH a cikin mafita kamar wutar lantarki, sunadarai taki, karfe, kare muhalli, magunguna, sinadarai, abinci da ruwan famfo. Tare da ORP Oxidation Reduction Electrode yana da daidaitaccen kayan aikin ORP.

1.2 Ayyuka Features

n High wayo: online pH ma'auni amfani da high daidaito AD canji da kuma guda chip microprocessing fasaha, iya kammala da yawa ayyuka kamar pH darajar ma'auni, zazzabi ma'auni, zazzabi ta atomatik diyya da sauransu.
n Lokaci nuni: kasar Sin online PH mita gina-a agogo guntu-guntu, zai iya nuna halin yanzu lokaci.
n Data ajiya: kayan aiki gina-ajiya guntu, zai iya adana tarihin bayanai na kwanaki uku da suka gabata, sauki mai amfani da neman.
n wanke sadarwa: kayan aiki da aka saita wanke sadarwa, za a iya tsabtace PH lantarki lokaci-lokaci ta hanyar shigar da solenoid bawul.
n 25 ℃ canji: 25 ℃ madaidaicin zafin jiki canji ga tsabtace ruwa da ammonia ultra tsabtace ruwa, cimma pH a nuna 25 ℃
n darajar, musamman dace da wutar lantarki tashar da yawa ruwa quality ma'auni.
n Strong anti tsangwama ikon: amfani da latest na'urori, impedance har zuwa 10-12 Ω; Yanzu fitarwa ta yi amfani da fasahar keɓewa ta hanyar lantarki mai haɗuwa, iko mai ƙarfi na tsangwama don cimma watsawa mai nisa. Yana da kyau electromagnetic jituwa.
n Multi sigogi nuna lokaci guda: nuna lokaci guda, pH darajar ko mV darajar, zafin jiki, fitarwa halin yanzu darajar a kan LCD allon. Yi amfani da high haske 128 * 64 LCD nuni module, m da kuma gani nesa.
n RS485 sadarwa dubawa: MODBUS RTU sadarwa yarjejeniyar sauƙaƙe haɗi da kwamfuta don sa ido da sadarwa.
n masana'antu sarrafawa babban kare: tabbatar da cewa kayan aiki ba zai mutu.
