Review on AR1890P2 Manometer Differential ±13 79KPa with Perfect Prime by Doug Hook

Half the price but still does the job. Highly recommended! This pressure gauge was recommended to me by a mechanic friend of mine. Half the price of other brands but works just as well. The seller has sensors of various shapes and types that are suitable for this device. They are sold separately and can be selected according to the measurement environment. There are many scales and units of measure, although I use few of them. When using both hoses, it shows the pressure difference. It has helped me check my furnace, air conditioner, and gas appliances without spending $$ on helpdesk calls! It used to be sold separately with soft plastic tubes. Stainless steel probe packages have recently become available, making them even more affordable. Minimal packaging that is good for the floor. Fast delivery. Definitely recommended!
