Dichlorofluoromethane

Dichlorofluoromethane is a colorless and odorless gas generally produced by fluorination of chloroform using a catalyst such as antimony trifluoride. It was used as a propellant and refrigerant before it phased out due to its contribution to ozone depletion. It is also known as Freon 21, R 21, halomethane, and Read more…

Deadweight Testers

Deadweight testers (DWT) are used to determine the operating pressure in a closed and compressed fluid system. They are named so because they use dead weights to balance the system pressure. Each applied weight is stamped with the equivalent amount of force that will be exerted on a predetermined area Read more…
