可逆氫參比電極RHE產地德國，*。有機，無機溶液均可適用。

可逆氫參比電極RHE用鍍有鉑黑的鉑片為電極材料，在氫氣氛中浸沒或部分浸沒于用氫飽和的電解液中，即組成了氫電極。其電極電勢E H2與溫度T、溶液的pH值和氫氣的壓力p H2有關。

pH值適(shi)用范(fan)圍：1-14

溫度：＜210℃

壓力；＜10MPa

參比電(dian)極(ji)是(shi)可逆(ni)電(dian)極(ji)體系(xi)，它在規定的(de)條件下具(ju)有穩定的(de)重現的(de)可逆(ni)電(dian)極(ji)電(dian)位。通常對參比電(dian)極(ji)的(de)主(zhu)要(yao)要(yao)求是(shi)：

（1）電(dian)(dian)(dian)極(ji)(ji)的可逆(ni)性(xing)比較好，不(bu)易極(ji)(ji)化(hua)。這就要求參比電(dian)(dian)(dian)極(ji)(ji)為可逆(ni)電(dian)(dian)(dian)極(ji)(ji)而且交換電(dian)(dian)(dian)流(liu)密度大(da)(da)(>10-5A/cm2)。當(dang)電(dian)(dian)(dian)極(ji)(ji)流(liu)過的電(dian)(dian)(dian)流(liu)小(xiao)于10-7A/cm2時(shi)，電(dian)(dian)(dian)極(ji)(ji)不(bu)極(ji)(ji)化(hua)。即使短(duan)時(shi)間流(liu)過稍大(da)(da)的電(dian)(dian)(dian)流(liu)，在斷電(dian)(dian)(dian)后電(dian)(dian)(dian)位能很快回(hui)復到(dao)原(yuan)來的數(shu)值。

（2）電(dian)(dian)(dian)極電(dian)(dian)(dian)位比較(jiao)穩(wen)(wen)定，且較(jiao)靠近零(ling)電(dian)(dian)(dian)位，不易極化(hua)或(huo)鈍化(hua)。參比電(dian)(dian)(dian)極制各后(hou)，靜(jing)置數天以(yi)后(hou)其電(dian)(dian)(dian)位應穩(wen)(wen)定不變。

（3）電(dian)(dian)位重現性(xing)好。不同(tong)(tong)人或各次制作的(de)(de)同(tong)(tong)種(zhong)參比(bi)電(dian)(dian)極(ji)，其電(dian)(dian)位應相同(tong)(tong)。每次制作的(de)(de)各參比(bi)電(dian)(dian)極(ji)，在穩(wen)定后(hou)其電(dian)(dian)位也應相同(tong)(tong)，其差值應小于lmV。

（4)溫(wen)度系數(shu)小，即電(dian)(dian)位隨(sui)溫(wen)度變化(hua)小。而且當溫(wen)度回復到(dao)原先(xian)的溫(wen)度后，電(dian)(dian)位應迅(xun)速回到(dao)原電(dian)(dian)位值。
