The number of Accuracy Checks and/or Calibration Adjustments available from a 30 liter alcohol gas tank depends on the regulator that is used and the amount of gas that is used with each test (how long the regulator button is depressed).
The 1.5 lpm (liter per minute) regulator will yield approximately 125 tests from a 30 liter tank if using approximately 8 seconds of gas per test.
We do not recommend using the 6.0 lpm regulator with 30 liter tanks because the expected yield is approximately 30 tests from a 30 liter tank using approximately 8 seconds of gas per test. This yield may be satisfactory to some customers, but our experience is that many customers find this yield unsatisfactory.
