HW/Weihrauch HW100 Manometer gauge very inaccurate question on replacing

DeanB · Feb 21, 2025

Does anyone make a digital manometer gauge for the HW100 the gauge on mine is crazy inaccurate, like 80 bar or more.. it started out being off by 20-40 bar and is getting worse.
Would like to put a digital one on if possible since they are said to be more accurate. Ive looked and cant find anything.

I never saw one myself, but I was curious. I found a youtube on the digital gauge, and a link to the vendor. I have no experience with airgun digital pressure gauges, but I used industrial digital gauges for vacuum systems/gas feed for many years. Those gauges were very reliable, but really uber expensive.
In my experience with gas feed regulator gauges, (positive pressure) the thing that killed them was abrupt changes in pressure. Like I said, I did gas into vacuum for coating and semiconductor applications, and fast feed would fatigue the the gauge pretty quick.
Pyramyd Air had one for 180 bucks, while analog is about 6X less.
Youtube linked gauge was under 50 bucks. Of course you need the correct thread interface for your system.
