hello all
not only new to this site but fairly new to refrigeration. I took the plunge and bought myself some cheap and nasty digital gauges with a built in vacuum gauge. When using the gauge it reads 0 for atmospheric and reduces as the vacuum draws to -762 microns or -1013 millibar. to me this does not corelate. Is it me, can perhaps one of you gents enlighten me. Surley those microns should be torr?
