  • Q:

    Will this gauge work with natural gas? I need a gauge that will read 3 inches w.g. during burner operation and up to 15 inches w.g. when the burner is off.

    I can put a valve to turn off the gas when I do not need to take readings. (for safety)

      A:

      Yes, the gauge will work with any compatible fluid, including natural gas - and covers the range you are looking to be within.
      Putting in a Tee with a valve would no disrupt the readings or harm the gauge.

  • Q:

    I want to measure the pressure inside a pressurized vessel with the gauge on the inside. I was told to look at either a differential gauge or a vacuum gauge. The pressure range from 4 psi to 20 psi

      A:

      This gauge will not cover the range you are looking for, 20psi is roughly 140kPa. Vacuum gauges are for negative pressures (pulling air out of the system) so I do not think that is what you need. And, differential gauges will tell you the difference between two environments, so I do not believe this is what you need either. We can help you find the right gauge by finding out more regardindg your application.
      Please contact our technical application specialists for additional assistance (contact information can be found on the product web page).

Comments about Ashcroft 14902.5 Dual-Scale Low-Pressure Gauge 0 to 30" H2O and 0 to 7.5 kPa:

Great gauge... it is accurate, consistant, and reliable. The movement is smooth. Only thing would be if the case was steel rather than plastic--It would keep better in my toolbox, but the price was a bit better than local suppliers. I use this to test gas pressure supplying Tankless Hot Water Heaters which most run in the range of 11-15" H20. just connect a 1/4" brass barb to the threads and then add a 3/8" vinyl hose and presto, a great tester for water heaters.
