This is actually a physics question. We can still help you with it, though. Give me a few seconds to push out a decent answer. :) Feel free to ask this again in physics where the question belongs. Welcome to Openstudy!

He would have used a Gravimeter. A gravimeter can test the strength of a gravitational field.

Confusionist, I think you're taking the question outside its intended boundaries.  I believe the question is looking for insight into how different types of weighing scales would behave under varying gravity.    A correct answer requires thinking about the difference in behavior of a counter-balance scale, and a spring scale.
