The a200 Thermo-Anemometer measures air temperature, air velocity, and relative humidity. The PosiTest® AIR Leak Tester detects air leakage in building envelopes and air barrier systems. Multi-Purpose test instrument that measures air velocity, wind speed, humidity, temperature .
The first test conducted by a testing crew is the dirty air traverse. That test uses the same sampling points when measuring velocities in the pipes. By measuring the true velocity flowing through the pipe, guessing an unknown velocity, as required by the ASME test procedure, is eliminated. After the dirty air velocity test is completed, the ...
