Review on Fieldpiece ASP2 Static Pressure Probes by Dragan Nelson

Required for the AR168 gauge to measure static pressure in the oven. Works perfectly. Excellent quality. Please note that these are NOT pitot tubes. They cannot be used for speed. Magnets are a must! I saw a design without magnets. Also purchase a 10 foot piece if using 1/8 inch ID hose to use both static differential pressure test hoses at the same time.
