Series O-4 Outside Air Temperature Sensor

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series O-4 Outside Air Temperature Sensors are great for monitoring ambient air temperatures in outdoor applications.

The temperature sensors are mounted in a NEMA 4X enclosure with integral mounting tabs. The mounting tabs can be used to surface or suspension mount the temperature sensors. The removable terminal block makes installation easy.

The Series O-4 can be used to measure outside air temperatures in building automation systems or room temperatures inside agricultural ventilation houses.
Features
  • NEMA 4X Weatherproof Housing
  • Surface or Suspension Mount
