Can anybody tell me if the Refco BM2-3-DS-CLIM gauges actually have scales on them for R22 R410A & R407C and can they be used for any other types of gas ?

I understand that they come with 1/4 SAE and 1/2 - 20 UNF, so all bases are covered.

Has anybody experience of using this Refco gauge and if so what are they like ?

Any advice on any other gauges on the market that cover R410A and other gases would be helpful.

Thank's
