How many strokes are necessary when using a pump type smoke tester to draw the correct amount of gases?

Using a pump type smoke tester, the appropriate number of strokes to draw the correct amount of gases is typically established through industry standards and practices. Within this context, ten full strokes are the accepted amount, as this ensures sufficient gas sampling to provide an accurate reading.

When conducting a test, achieving a reliable sample is critical for assessing emissions and performance. The pump's design and the associated calibration inputs necessitate a specific stroke count to create the proper vacuum and ensure that enough gas is transported into the testing chamber. This reliability in the testing process helps maintain compliance with regulations and industry standards pertaining to emissions and equipment efficiency.

Understanding the necessity of ten strokes underscores the balance between sufficient sampling and accuracy in testing, which is a vital aspect for professionals working in oilheat systems.
