Does ITV have a gauge port?

Up until Oct.2008, there was a gauge port as standard, but it has been taken away as ITV already has a digital display as standard. If you want to use a pressure gauge, please consider either using a tee connection at the OUT side to install it or add "-X400" suffix ("-X401" for CE-Marked version) to the model number, so SMC can produce a special ITV with a threaded gauge port.
