Shock Pump for Vessel Pressure?

[Hitech]

Hi there, Any idea if this shock pump can be used for vessel pressure?

Yep I have one and use it as i already had it so no expense.
Mine was bought for & fits my mountain bike suspension hence my guage goes upto silly bar readings. The average vessel is around 1 bar on a combi..at the lower end on my guage so I just verify the pressure with a digital tyre guage incase the pump is out.
