Just wondered how accurate you think your non-digital gauges are ???
And how you calibrate them, i have calibrated my with a bottle of gas but now read wrong at zero pressure.

I trust my gauges and the dry ones do need ressetting to zero every few weeks. Because they are in the van they get bumped and do lose their zero.

I use good gauges that have the oil dampner inside and they do not need zeroing very often, but they still require changing every few years.

You could always buy a pressure calibration tester

At £1,655.00 I'll have two please one for every day use and one for weekends :D.

When I worked at Hussmanns to get the ISO 9000 rating or whatever it was, we had a calibration bay where all our tools and equipment were calibrated on a regular basis.

Nice thought, but at that price i would need a loan and the interest rates are to high at the moment.

Being a frugal person i just keep a good quality guage with a tee and use it as a standard and calibrate the work guage to it and calibrate it at the middle scale about where I use it.
