ALS Reversible Hydrogen Electrode kit
Features:
- Reversible hydrogen electrode that achieves good potential stability as a reference electrode for electrochemical measurements by generating and capturing hydrogen gas through electrolysis of an acidic solution.
- It makes unnecessary the complicated and dangerous set-up of the hydrogen cylinder and avoids the large volume of hydrogen gas exhaustion, even though it has a good potential stability.
- By using a double junction chamber, the electrode can be used with solutions other than acidic solutions.
- H2G1 Portable Hydrogen Generator, which can be easily filled with hydrogen gas without a potentiostat, is also available.
The Reversible hydrogen electrode (RHE) kit can be used without Double junction chamber when strong acid (<pH 2, such as 0.5 mol/L sulfuric acid) is used as an electrolyte solution.
