300 Bar tank gauge

[Hudo]

Hi all, 

Ive got a 12l steel tank with a Din valve. Im wondering if anyone has or can point me in the direction of a valve with a gauge that reads off the tank incorporated in its design. 

Currently I will have to screw in an adaptor then put my dive regs on to check the pressure. 

Thanks

Hudo

Assuming your tank has a standard 7/8-14 thread, Airtanksforsale.com or Airguns of Arizona have what you need.

Maybe this one? It comes in two thread sizes with gauges for tank pressure and fill. http://experthpa.com/cart/cart.php?m=product_detail&p=112
