PH酸度計的?儀器維護及注意事項

發布日期:2022-04-27 點擊率:102

(1)儀器應置子干操的環境中,防止灰生及腐般性氣體侵入。

(2)玻璃電極括口及甘汞電極按線柱必須保持清潔。

(3)為防止玻璃電極球泡破碎,安裝時甘表電極底部應長子球泡,使球泡在搖動時不會碰到杯底。

(4)玻璃電極導線間絕緣電阻不得低于1011Ω。

(5)若積下測量開關時,指針偏轉過大,應立即放開測量開關,檢査電極是否浸入溶液中,檢査各旋紐所處位置,

(6)轉動溫度補償器旋組時不要用力過大,防止緊固螺絲的位置發生轉動,使指示的補償溫度不準確。

(7)預熱時間最好在1h以上,使零點有比較好的穩定性。

(8)儀器不用時將量程選擇開關置于“0”位上,即電表短路,搬動時電表不要損傷。
