The Minneapolis Duct Blaster® is a calibrated air flow measurement system designed to test and document the airtightness of forced air duct systems in both houses and light commercial buildings.

The Digital TrueFlow Air Handler Flow Meter provides a simple and accurate measurement of airflow through residential air handlers. The Digital TrueFlow Meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process using a pre-cut or cut-to-fit adapter plate (additional plates sold separately).

Two-channel digital micro manometer for pressure and flow measurements.  Primarily used with Minneapolis Blower Door™ and Minneapolis DuctBlaster.

The DG-8 Digital Pressure Gauge is a cost-effective and highly accurate single channel micro-manometer. Never before has TEC accuracy been more accessible for critical building pressure measurement applications.

Protect your DG-1000 in the field with a shock-absorbing protective boot! The red silicone boot fits the DG-1000 like a glove while offering full access to all the pressure taps, connection ports and case magnets for mounting to your gauge board.

The Exhaust Fan Flow Meter is designed to make quick and accurate measurements of airflow through residential bathroom fans, whole house ventilation fans and other exhaust devices. Smaller, lighter and easier to use than conventional flow measuring hoods.

The Pressure Pan is a duct leakage diagnostic tool which is used along with the Blower Door and digital pressure gauge to identify exterior air leaks in forced air duct systems. It is most effective when a significant portion of the duct system is located outside the conditioned house space (e.g. attics, crawlspaces, garages). Generally, the higher the pressure pan reading, the leakier that part of the duct system is to the outside. Pressure pans do not directly measure leakage rates. Rather, a pressure pan is used to measure the pressure difference between the house and a duct run during a Blower Door test. This pressure reading can be used to estimate the degree to which a particular duct run is connected to the outside.
