Model EE08 OA
Outside Air RH and Temperature Probe With Analog and Serial Output

This is a small compact probe that is design as a replacement part for weather stations but can also be a very cost effective outdoor sensor for economizer control if a building control system is available to calculate dew point. All calibration information and analog circuitry is in the probe body.  Serial output uses E+E E2 Serial Protocol.

Enclosure: NEMA 4, Plastic Housing

RH Accuracy: ±2% RH 0-90% RH

Temp Accuracy: ± 3.6ºF@ 70ºF

Calculated Dew Point Accuracy: ± 1ºF Td (50-75ºF, 60% RH)

Outputs: 0-1V, 0-2.5V, 0-5V, Two Wire Serial (E2 Protocol)

Accessories/Options:

Attached 8 wire (Model E) or screw-in 8 pin cable connection (Model D)

Radiation Shield & Mounting Bracket (HA010506) (Model D Probe Required with Radiation Shield)

PC interface program for calibration and logging.

Passive Temperature output option

Key Features

High accuracy and excellent stability. For outdoor environments, calibration should not be necessary for 10 years or more. (Contact AirTest for long term performance data.)

Fast response.  T90 = 6 seconds

All sensors have two point calibration adjustment to tow points.

Radiation shield to eliminate effects of solar radiation, rain snow and wind.

For harsh and polluted environments a protective environmental coating is available.  Ideal for coastal areas or marine applications subject to salt spray.
