4 use distilled water

supper purity hydrogen generator  Introduction: 


      DH-300 model hydrogen generator, use Palladium filtration membrane technology

could produce ultra pure H2 gas, which is much purity than H2 cylinder. Could meet requirement for high precision equipment, such as accurate GC, polarization spectrometerepitaxial semiconductor nuclear physics experiment etc, which must use supper high purity hydrogen gas.

       DH-300 is through water electrolysis technology, produced hydrogen through palladium membrane filtration.

 This palladium membrane only allow H and H isotope

Pass by, so final output hydrogen purity could guarantee reach more than 99.99999%


99.99999% purity, H2: 0--300ml/min, Palladium technology



   Compared with other hydrogen generator, DH-300 does not have very high requirement for input water, 

normal distilled water is enough.  And also don't need any desiccants(such as silica gel or molecular sieve), free of maintenance. Not only save maintenance fees, but also decrease gas leakage while often replace desiccant

   DH-300 whole automatic control, no hydrogen storage inside, 

have short of water, over pressure, hydrogen leakage safety protection, easy and reliable to use. 



Technology Figures:


1. H2 output flow: 0--300ml/min

2. H2 output purity: >99.99999%

3. H2 output pressure: 0--0.5MPa

4. H2 output Fluctuation: < 0.0001MPa

5. Input power: 300w

6. Voltage: 220V, 50--60HZ

7. Input water requirement: normal distilled water

8. No need desiccant(such as silica gel or molecular sieve), free of maintenance 

9. H2 Produced on demand, no storage, greatly safety. Alarms functions

10. Size: 380*200*370mm

11. Weight: 15kgs
