EE660 Low Air Velocity Transmitter | E+E Elektronik Cleanroom Sensor

EE660 LOW AIR VELOCITY TRANSMITTER  | E+E ELEKTRONIK CLEANROOM SENSOR

A high-precision air velocity transmitter optimized for measuring very low airflows down to 0.15 m/s (30 ft/min) in sensitive environments.

The EE660 by E+E Elektronik is a specialized air velocity transmitter designed for the precise measurement of very low air speeds, making it a critical component for cleanroom environments and laminar flow control.

EE660 LOW AIR VELOCITY TRANSMITTER  | E+E ELEKTRONIK CLEANROOM SENSOR

The EE660 utilizes advanced hot-film anemometer technology with an E+E thin-film sensing element to provide exceptional long-term stability and high resistance to pollution. It is specifically engineered for laminar flow monitoring and cleanroom applications where accuracy at low velocities is paramount. The device features a user-friendly design with a large, rotatable display and is configurable via onboard jumpers or software to adapt to various measurement ranges and response times.

PRODUCT USES:

  • Laminar Flow Control: Monitoring airflow in pharmaceutical and electronics cleanrooms.
  • HEPA Filter Monitoring: Ensuring proper airflow through high-efficiency filters.
  • Biosafety Cabinets: Maintaining safety standards in laboratory exhaust systems.
  • High-End HVAC: Precision control for specialized ventilation in hospitals or research facilities.
