Cosmo Instruments Co., Ltd. products

The leak master LM-1C is ideal for everyday inspections of air leak testers. The LM-1C Series is used as an ideal determination device, so it can be manufactured with your desired leak volume. Please specify test pressure and leak volume in the range below when ordering. Leak rate is indicated both by the "equivalent flow rate" and the "conversion flow rate" in Cosmo. When calibrated with the equivalent flow, leak flows not affected by the temperature and atmospheric pressure are displayed.
