Tired of inaccurate surface pressure gauges. Would like to buy a new gauge which is within spitting distance of the pressure. Wouldn't object to buying a digital one either as it'll be better for blending. A larger 3"/75mm would be nice. I have the DIN connector and pressure relief valve from an old gauge that consistently reads 10% low.
I realise that yer gets what yer pays for.
So, to start off, are there any "quality" brands which are generally good?
Digital gauges. These vary a lot in price. Would buying the eBay advertised "Digital DIN cylinder contents pressure check gauge 0 - 400 Bar 0.5% Accuracy" be a waste of the ~£120? Or going for the Narked one for a lot more?
Any other recommendations?
