Optional extras    matters need attention   1. Test cycle is generally not more than half a year, part of medium pressure fluctuation, the use of frequent, high accuracy requirements, as well as the factor of safety requirements more stringent, can according to the specific situation will be appropriate to shorten the test cycle. 2. The working environment should be no corrosive gas PACKAGING ABOUT US   CONTACT US
