Anyone ever heard of Additel pressure gauges?

I have a 40,000 PSI one here wondering if these are any good or not?

I don't know about their pressure gauges but their new line of automated pressure calibrators (ADT 761) are awesome. The ones I calibrated regulated inches of water to 5 digits. Easy to calibrate/align too.

Can't say about the gauges, but we use and like the pressure calibration pumps.
