Review on AR1890P2 Manometer Differential ±13 79KPa with Perfect Prime by Trae Joubert

didn't even know this gauge existed until we started converting our house to propane and the instructions said to use it. It was convenient and we were able to get the job done at a great price. This allowed us to set all the pressures. My father worked for a gas company a few years ago and helped my husband with the installation for many years. He was impressed by this instrument because it was done differently at his age. Needless to say, he actually bought and used it.
