    Regulators are used to ensure you receive the required flow of calibration gas for your application. Based on the cost-efficient design of its diffusion based gas detectors, MSA is able to use 0,25 lpm regulators. This save users’ money by delivering calibration test gas at a low rate of 0,25 lpm versus 0,50 lpm which is the market standard.
