S80 cylinder identification

[Caveman]

Hi guys,

I was in a diving store and they had recently brought in some new stock of S80 cylinders. The build quality looked amazing but the only thing is that that the markings are unfamiliar to me. I have not seen tanks like these before, I am normally used to coming across Luxfers or Catalina's.

Can anyone here identify the manufacturer from the markings?

I had not thought to ask while I was there and I will give them a call in a few days but in the mean time was wondering if this looked familiar to any divers here.

I'm a tad confused, as CHN is not something I recognize. Usually cylinders made from China are stamped with CN and not CHN. Regardless, I assume this cylinder comes from China.

If you could take a picture with the manufacturer identification clearly visible, identifying this cylinder would be much easier. You can find the manufacturer stamp to the left of the born date and unfortunately none of your pictures has it visible.

Hi, thank you. I am a bit annoyed with myself, I can see that stamp would have probably been my answer but for some reason I thought CHN had something to do with the manufacturer info so I didn't think to focus on the stamp. I will update this thread when I have a clearer picture

I cannot directly answer your question. Please let us know what you learn. That said, looks can be deceiving. If these cylinders are in fact made in China I would not buy them. In general, I do not trust anything made in China.

"PH 310.5 bar" is very odd. That's not a standard service nor test pressure in scuba

Test pressure? 207 is to the left of that.

207 * 1.5 = 310.5. So the Pressure - Hyrostatic (PH) is 1.5 times the Pressure - Working (PW). 5/3 or 3/2 of the working pressure for the hydrostatic test is common. It just depends on where one is located.

If these are the same, that shop is highly questionable to say the least.
