What Water Pressure Gauges (2 1/16th) are you guys using to monitor your alky injection?

The only 'affordable' 0-150 psi gauge I see is oil pressure...would this guage work ok?

Coolingmist sells a digital water pressure gauge but it's $130, but that's out of budget now.

Thanks in advance.

got this from mcmaster.com, glycerin damped - dampens pressure pulses from the diaphgram pump
