1，天津排水口VOCPH計、測量時，應(yīng)先在蒸餾水中（或去離子水）洗凈，并用濾紙吸干水分，防止雜質(zhì)帶進被測液中，電極球泡和液絡(luò)部應(yīng)完全浸在被測液內(nèi)。 2、電極不用時應(yīng)洗凈，**加有3.5M氯化鉀溶液的保護套，或?qū)㈦姌O**加有3.5M氯化鉀溶液的容器。 3，天津排水口VOCPH計、檢查接線端子處是否干燥，如有沾污，請用無水酒精擦拭，吹干后使用。 4、應(yīng)避免長期浸泡在蒸餾水或蛋白質(zhì)溶液中，并防止與有機硅油脂接觸。 5、使用時間較長的電極，它的玻璃膜可能變成不透明或附有沉積物，此時可用鹽酸洗滌，并用水沖洗。 6、建議用戶每月對電極進行清洗一次以及配合儀器校正。 PH計電極圖片 PH計電極圖片 7、當(dāng)您用以上方法對電極進行維護和保養(yǎng)時仍不能進行校正程序及正常測定，說明電極已無法恢復(fù)響應(yīng)，請更換電極。若是手動調(diào)節(jié)的pH計，應(yīng)在兩種標(biāo)準緩沖液之間反復(fù)操作幾次.天津排水口VOCPH計</p><div style="width:100%;text-align: center;"><img

產(chǎn)品簡介銻電極酸度變送器是集PH值檢測、自動清洗、電信號轉(zhuǎn)換為一體的工業(yè)在線分析儀表。適用于化工、冶金、制藥、造紙、制糖、環(huán)保等行業(yè)的PH連續(xù)測量和控制。特點l電子轉(zhuǎn)換單元為模塊化結(jié)構(gòu)，抗震防潮，故障率低。l采用高純銻做測試電極、銀—氯化銀環(huán)形電極作參比電極的“集成體酸度傳感”和“膜鹽橋裝置”技術(shù)獲兩項國家**。l瑪瑙刀雙刮板式機械清理裝置可使測量電極與參與電極同時進行清洗，具有良好的抗結(jié)垢能力，可在濁度高，粘性大，易結(jié)晶或結(jié)垢的介質(zhì)中長期連續(xù)工作而不需要維護l變送器輸出4—20mA標(biāo)準信號，除與PHT型酸度計二次表配套使用外，還可以與DDZ—III型儀表連接。l技術(shù)含量高，結(jié)構(gòu)緊湊，性能可靠。l內(nèi)參比溶液高位槽使參比點擊不受反滲污染，基準電位穩(wěn)定，漂移小。結(jié)構(gòu)原理l1.測量原理由銻電極與參與電極組成的PJ值測量系統(tǒng)，在被測溶液中銻電極表面生成三氧化二銻（Sb2O3）氧化層，金屬銻面與三氧化二銻之間形成電位差，其電位差的大小取決于三氧化二銻濃度，該濃度與北側(cè)溶液中氫離子（H﹢）活度對應(yīng)。如果把銻、三氧化二銻和水溶液的活度都當(dāng)作1，其電極電位可用能斯特方程表示為：E=Esb?Sb2O3+。陜西在線VOCPH計氯化鉀溶液中應(yīng)該沒有氣泡，以免使測量回路斷開。</p><div

利用。例3．將pH值為8的NaOH溶液與pH值為10的NaOH溶液等體積混合后，溶液中氫離子濃度**接近于()×10－10mol/LB.(10－8＋10－10)mol/LC.(10－8＋10－10)mol/LD.(1×10－14－5×10－5)mol/L解析：按照，混合液的pH＝，對各選項分別試之，并舍去[H+]較小的，再取負對數(shù)。A的pH＝，B為－lg(×10－8)＝－lg(5×10－9)＜9；C為－lg10－8＝8；D為負數(shù)的對數(shù)，不正確。故應(yīng)選A。例4．[OH－]＝10－6mol/L的NaOH溶液10mL加入10－5mol/L的NaOH溶液100mL后的溶液的pH值()A.等于8B.大于8C.小于8D.無法判斷解析：由于前者濃度比后者小，且體積*為后者的1／10，即使加入前者100mL于后者溶液中(即相當(dāng)于等體積混合)，按，溶液的pH值也只減少，還是比8大。故應(yīng)選B。例5．某氨水的pH＝X，某鹽酸的pH＝Y(jié)，已知X＋Y＝14，但X＞11。將上述氨水與鹽酸等體積混合后，所得溶液中各種離子濃度的關(guān)系正確的是()A.[]＞[Cl-]＞[OH-]＞[H+]B.[]＞[Cl-]＞[H+]＞[OH-]C.[Cl-]＞[]＞[H+]＞[OH-]D.[]＋[H+]＝[Cl-]＋[OH-]解析：如果將氨水換成一元強堿，按，反應(yīng)后溶液pH＝7。但pH值相同且體積相等的氨水合一元強堿，氨水中氨氣的物質(zhì)的量比強堿大得多；故該氨水與鹽酸反應(yīng)時，氨水過量很多，溶液應(yīng)顯堿性。PH酸度計儀器的級別0.2級、0.1級、0.02級、0.01級、0.001級.</p><div

這并非特別先進的“高科技”過程，而是電極制造中非常關(guān)鍵且重要的一步。事實上，玻璃厚度決定了其電阻，進而影響其輸出。溫度補償由于pH電極和pH測量均對溫度敏感，因此儀器設(shè)有溫度補償功能。溫度可通過手動或自動方式進行補償。手動補償功能需要單獨測量溫度值，可采用近似溫度值來設(shè)置pH計的手動補償溫度。在自動補償（ATC）設(shè)置中，單獨溫度探頭中的信號會傳輸至pH計，因此能準確地確定樣本在該溫度下的pH值。緩沖溶液緩沖溶液是指具有恒定pH值且能夠避免pH值大幅度變化的溶液。緩沖溶液通常用于校準pH測量系統(tǒng)（電極和測量計）。兩個電極的輸出之間可能存在微小差異，而且電極輸出隨著時間推移也會產(chǎn)生變化。因此，必須定期校準pH測量系統(tǒng)。緩沖溶液適用于各種pH值，它們既可以是預(yù)混合的液體，也可以是方便使用的干粉膠囊。大多數(shù)pH計需要針對數(shù)個pH值進行校準。***個校準數(shù)值通常是在等電位點（電極在pH7，25℃條件下所產(chǎn)生的信號為0mV）附近，第二個校準數(shù)值通常是pH4或pH10。比較好選擇盡可能接近被測樣本實際pH值的緩沖溶液。但是，選擇**辨率的儀器可以比較大限度地克服或消除電計對測試誤差的影響。天津排水口VOCPH計</p><p
