Maybe they steam the ammonia?��

Or maybe it's made by the Ammonia Gauge Company. LOL

I don't know, but 300psi of steam ain't much.

I wouldn't know, haven't worked on "big" steam systems. Actually I've never worked on ammonia systems, either, but a quick look at an ammonia chart

shows 90 degree condensing is around 175 psi, so the range of that gauge makes sens

Yup, just saying it's no steam gauge.
