Leak testers and related products
- Q1.What are the advantages of using air leak testers?
- Q2.What is the difference between the leak testing methods of differential pressure detection and gauge pressure decay?
- Q3.What are some units describing leaks?
- Q4.The change in differential pressure is what is detected. How is it that they can also directly read and display the flow rate?
- Q5.What is the difference in having positive pressure and negative pressure as the test pressure?
- Q6.What is the difference between the MASTER comparison method and the simultaneous comparison method? Also, what is the multi-comparison method?
- Q7.What is the volume equivalent? What is the relationship between the volume equivalent and the leak?
- Q8.How are the pressurization time and the stabilization time determined?
- Q9.Is there anything that can act as a standard for leaks?
- Q10.Please explain the structure of the MASTER chamber and the advantages of using it.
- Q11.Is there a good way to perform a leak test on WORK with some oil residue?
Daily leak sensitivity checks and calibration
- Q1.Why do leak sensitivity and other settings require daily checks?
- Q2.What kind of devices are available for easily performing daily leak sensitivity checks?
- Q3.Which is more suited to daily checks—the leak MASTER or the leak calibrator?
- Q4.Can the leak MASTER or leak calibrator be connected easily?
- Q5.What devices are necessary to show leak rate, not in differential pressure, but in flow units?
- Q6.When calibrating leaks, what is the difference between using a leak MASTER and using QLC or the like of the volumetric change method?
- Q7.Can the same calibrator be used for the daily checks and for leak calibration?
- Q8.What is the difference between the calibrators?
Pressure, flow meters and related topics
- Q1.Can the average pressure be measured when the pressure fluctuation is high?
- Q2.Are there any restrictions on fluids to be measured for pressure?
- Q3.Can users perform pressure calibration on their own?

- Q5.How can the AF-2201 (AF-2200N) be initialized?
- Q6.How can the DF-2800/2810 be initialized?
- Q7.Can flow of liquids be measured?
- Q8.How much inaccuracy occurs when measuring the flow of gases other than air?
