Accurately measure outside airflow rates in classroom unit ventilators with a -U sensor system.

Classroom unit ventilators are susceptible to significant outside air intake flow rate variations resulting from changing wind and stack pressures. In addition, damper hysteresis makes it difficult to reproduce initial TAB setup over time.

Install a -U in the outside air intake of your classroom unit ventilator for monitoring and/or control of minimum ventilation rates (consult EBTRON for make and model compatibility).

Available with either the STA104 or STN104 transmitters only.
