The DAV anemometer is an advanced device designed for continuous air flow velocity measurement in mine tunnels, shafts, corridors, and for local signaling of airflow loss. The high-brightness optical element signals hazards at the entry into a controlled area. The measurement head can be placed up to 30 meters away from the base unit.

The AS-4ES anemometer is used for continuous measurement of air flow velocity in mine tunnels, shafts, corridors, and for local signaling of airflow loss according to a preset alarm threshold. The high-brightness optical element enables hazard signaling at the entry into the controlled area. The AS-4ES anemometer is powered from the surface station via a telephone line. Data transmission occurs over the power line. It is possible to connect up to four anemometers on a single line.

The AS-3ES anemometer is designed for continuous measurement of air flow velocity in mine tunnels, shafts, corridors, and for signaling the loss of airflow according to a preset alarm threshold. Connected to an alphanumeric display, it enables hazard signaling at the entry into the controlled area.
