digital chiller differential gauge

[knight rider]

i've been using an old diff gauge to check the pressure drops across chillers / water cooled condensers , i was thinking maybe it could be time to replace for a digital type,
can any one recommend a decent set or should i stick to my old trusted gauge

what type off gauge do you guys use ?

It's tricky, but you can't go wrong with the old Paul Poddy gauges. I know thy went to Perflow and then ....

It all depends how often they are used and are you happy with what you've got - will you trust the electronics ??

Alnor Model number HM680 is the greatest thing I have ever used. A little expensive unless you use the a lot
