The EE08 is a probe for the highly accurate measurement of humidity (RH) and temperature (T) over
wide RH and T ranges of 0...100 % RH and -40...80 °C (-40...176 °F).

Typical application fields of the probe are

Meteorology / weather stations



Humidity / temperature data logging



Incubators



Fermentation chambers



Green houses



Snow machines



Dry storage facilities



There are two types of probe, the EE08 with cable (type E8) up to 5 m (16.4 ft) length and the EE08 with
connector (type E11). For the latter, connection cables with length 1.5 / 3 / 5 / 10 m (5 / 10 / 16.4 / 32.8 ft) are
available as accessory.

User Manual for EE08 Humidity / Temperature Probe

For outdoor operation the use of an appropriate radiation shield is of paramount importance. The
EE08 is compatible with rotational symmetric radiation shields which protect it against rain, snow and
overheating caused by direct sunlight (available as accessory HA010502, suitable for type E8 and
HA010506, suitable for type E11).

Outdoor operation with radiation shield: wall mount or pole mount. Please mind the mounting



instructions included in the manuals of HA010502 and HA010506.

5 Maintenance

The use in dirty, dusty, polluted environment might arise the need for cleaning the sensing head and
replacing the filter cap. In such a case please see the Cleaning Instructions at www.epluse.com/ee08.

Do not touch the humidity sensor!

6 Calibration / Adjustment

Definitions

Calibration documents the accuracy of a measurement device. The device under test (specimen) is



compared with the reference and the deviations are documented in a calibration certificate. During
the calibration, the specimen is not changed or improved in any way.

Adjustment improves the measurement accuracy of a device. The specimen is compared with the



reference and brought in line with it. An adjustment can be followed by a calibration which documents
the accuracy of the adjusted specimen.

To carry out a one point or a two point calibration / adjustment, the E2 / RS232 converter (available as
an accessory, order code HA011005) and the EE-PCS Product Configuration Software are necessary.
The EE-PCS is freely available at www.epluse.com/ee08.
