總體介紹：
- gaskatel pH電極pHydrunio -- 氫-pH-電極，是世上第一個可在市場上訂購到的氫pH電極。
- pHydrunio專利DE 10 2011 113 941。
- gaskatel pHydrunio結合一個可逆的氫電極在您的溶液中作為測量電極，及一個氫參考電極在內部電解質中作為參考電極，它在交貨時即已啟用，您所需要做的，只是將它填入電解質緩衝液7(Gaskatel)，而在 24小時後，pHydrunio便可使用。配備由一個內部來源提供10個月的氫氣。氫電池可更換，同時，在軸內的氫氣可確保控制的電解質從隔膜放電。pHydrunio是由塑膠製成，因此，不能密封。
- 電解質具有已知的pH值、填入及等待24小時，然後，測量。
- 使用時間10個月，然後，氫電池可以輕易更換。
- 塑膠製成，不易斷裂。
- 控制的電解質放電。
- 適用於pH值-2到pH值16。
- 可用於濃縮的含氟介質。
- 軸直徑12mm，軸長160mm。

pH-Electrode pHydrunio -- the first combined pH-Electrode of two hydrogen electrodes.
Measurement of pH by use of Hydrogen potential:
- Maintance free and unbreakable
- Made from PTFE or PP
- PTFE-diaphragm
- 2 mm gold-plated socket contact (Hydrogen electrode)
- 2 mm silver socket contact (Silver-Silverchloride electrode)
- 3 mol/l KCl (~ 2 ml)
- Length 105 mm (without silver socket contact)
- Length without the electrode head 80 mm
- Diameter 12 mm
- With PT100 sensor
- pH-range from pH -2 bis pH 16
- In fluoride containing electrolytes up to 500.000 ppm
- For use in nonaqueous electrolytes
Overview:
- pH-Electrode pHydrunio – Hydrogen-pH-Electrode is the world’s first commercially available hydrogen pH electrode:
- pHydrunio (patent DE 10 2011 113 941).
- It combines a reversible hydrogen electrode as a measuring electrode in your solution with a hydrogen reference electrode in an internal electrolyte as a reference electrode. It is delivered activated. All you need to do is fill in the electrolyte buffer 7 (Gaskatel), and pHydrunio is ready for use after 24 hours. It is supplied with hydrogen gas for 10 months by an internal source. The hydrogen cells can then be replaced. At the same time, the hydrogen inside the shaft ensures controlled electrolyte discharge from the diaphragm. It is made of plastic and therefore can not be sealed.
- Electrolyte with known pH-value, fill, wait 24 hours and measure
- run time 10 months, then the H2 cells can be easily exchanged
- unbreakable because made of plastic
- controlled electrolyte discharge
- applicable from pH -2 to pH 16
- can be used in concentrated fluoride-containing media
- Shaft diameter 12 mm, shaft length 160 mm
