A miniature (0 to 15 psi range) pressure gauge and a miniature dual scale ( 0 to -30 in. Hg/0 to -75 cm Hg) vacuum gauge requires less space than most gauges.
The dial face is just under 1 in. diameter and the front to back depth is 1 7/64 in. Center back end connections have a 1/8 NPT external thread and a 10-32 UNF internal thread. The gauges are constructed of brass and movement is geared. Accuracy is 3%-2%-3%.
