Coal Mining Ventilation Resistance Meter

Â

Introduction:

1. Applicable for test of wind speed, absolute pressure, differential pressure, temperature and humidity. CFZZ6 can also test CH4 concentration.

2. Comprehensively analysis the loss of ilation resistance, local resistance of fan station, resistance distribution of ventilation system and wind pressure, distribution of air volume.

3. For coal mining, non-coal mining, tunnel and other roadways, provide them a scientific basis for ventilation system’s design, study, safety evaluation, construction and mining.

Note: CFZZ5 is equipped with hot-film wind speed sensor.

CFZZ6 can be equipped with hot-film or impeller-type wind speed sensor.
