特長
pH滴定のための複合pH 電極。これは、特に以下の用途に適しています:
- 困難なサンプル、粘性のあるサンプル、あるいはアルカリ性のサンプルにおけるpH滴定
- 高温時
固定グランドジョイントダイアフラムは汚れに対して耐性があります。
参照内部液: c(KCl) = 3 mol / L、保存液で保管。
代替: T>80°Cでの滴定用参照内部液: イドロライト、イドロライトで保管。

- Reliable measuring results over long periods of time can be guaranteed only if the pH glass membrane and the diaphragm receive preventive and regular care. Cleaning by etching with toxic chemicals or applying mechanical treatment to the diaphragm is not only complicated and expensive, it also accelerates the ageing of the pH glass electrode.The cleaning solution was developed for easy and gentle cleaning of pH glass electrodes. Regular use can considerably prolong their service life.This cleaning solution is also part of the pHit kit.
