Model SDMN6 Dual Port Manometer and Pressure Switch Tester measures gas and static pressure and accurately tests pressure switches by simulating a draft with an internal pump.
Model DDSM1 draft simulator allows HVAC professionals to accurately test pressure switches and calibrate adjustable pressure switches to any furnace. This allows technicians to carry adjustable switches on their trucks, instead of switches for a variety of furnaces, said the company.
The Draft Simulator from Draftrite LLC is designed to safely and accurately test pressure switches by simulating a draft inducer — there is no need for the furnace to be on.
