- 將HydroFlex®作為可逆氫電極(RHE)使用：
- HydroFlex®日常實驗室的例行程序中，最常見的使用，莫過於作為RHE的應用。
您只須將HydroFlex直接浸入溶液中，其優點是顯而易見的，您不需要一個液接界面，您沒有擴散電位，而且，也不會因為離子從您的參考系統流出，而污染您的溶液。 - 由於HydroFlex除了每6個月定期更換H2濾匣外，並不需要任何維護，因此，非常適合長期測試使用。
- HydroFlex®日常實驗室的例行程序中，最常見的使用，莫過於作為RHE的應用。
- 將HydroFlex®作為一般氫電極(NHE)使用：
- 假如將HydroFlex®放入濃度1 mol/l的鹽酸與環境壓力中，HydroFlex®可作為一般電極使用。
在一般氫電極(NHE)與標準氫電極(SHE)之間的電位差很小，實驗的複雜度容易掌握。
- 假如將HydroFlex®放入濃度1 mol/l的鹽酸與環境壓力中，HydroFlex®可作為一般電極使用。
- 將HydroFlex®作為標準氫電極(SHE)使用：
- 將HydroFlex®用作為標準氫電極(SHE)的實驗複雜度相當高。
在此種情形下，必須將HydroFlex®浸入氫離子活性為1 mol / l的溶液中。其溫度必須是298.15 K(77°F)，而壓力必須是1013,3 hPa(14,697 psi)。由於這些標準條件的驗證具有挑戰性，因此，在日常的實驗程序中，若要將HydroFlex®作為標準氫電極(SHE)使用，通常並不適當。

- HydroFlex® as RHE (Reversible Hydrogen Electrode):
- The most common use of HydroFlex in the daily lab routine certainly is the application as RHE. You simply dip HydroFlex into your solution, directly. The advantages are obvious. You don't need a liquid junction, you don't have diffusion potentials and you don't contaminate your solution by ions flowing out of your reference system.
- As HydroFlex needs no maintanance except the regular exchange of the H2-Cartridge every 6 months, it is very well applicable for long-term tests.
- HydroFlex® as NHE (Normal Hydrogen Electrode):
- HydroFlex works as a NHE, if you put it into hydrochloric acid at a concentration of 1 mol/l and ambient pressure. The potential differences between a NHE and a standard hydrogen electrode are small while the experimental complexity is easily manageable.
- HydroFlex® as SHE (Standard Hydrogen Electrode):
- The experimental complexity of using HydroFlex as SHE is comparably high. In this case HydroFlex has to be dipped into a solution with hydrogen ion activity of 1 mol/l. The temperature has to be 298,15 K (77 °F) and the pressure has to be 1013,3 hPa (14,697 psi). As the verification of these standard conditions is challenging, the use of HydroFlex as SHE usually is irrelevant in the daily routine.
