How to Measure Gravity, or Gravitational Pull?

[cleanenergy]

Dear Friends & Colleagues,

I would like to propose the following Question, Is there a way to technically Measure the Gravitational Pull of a body? (body being any of the following: molecule, physical item like a rock, or a planet or a star).

I am not looking for a sample of a falling body, and the relation to speed & mass & time vs air resistance. I am looking for a way to physically or electronically measure the Gravitation pull or force of a body.

Thank You and hope to hear from many folks, as this would help me figure out another part of an even larger equation.

Thank You for Your Great Example, I also found a Gravimeter, it manufactured by
http://www.zlscorp.com/products.htm , which is what I am looking for , Thank you again, and hope to hear from others...
