[MW:17178] Vacuum test pressure gauge details required

Dear Experts,

 

I need to do vacuum testing of column at 40mm Hg (abs). Least count of gauge should be 0.5 torr.

My code of construction for manufacturing of column is ASME SEC VIII Div. I

How should I select pressure gauge?

Is the Pressure Gauge of range 0-760 mm Hg OK?

Does the pressure gauge with the range of 0-760mm Hg with least count of 0.5 mmHg available in the market?

 

Thanking you in advance.
