- his device is not appropriate for safety, emergency stop or other critical applications where device malfunction or failure could cause injury to human beings.
Intended Use
The EE08 is intended for the humidity (RH) and temperature (T) measurement in
applications that require accurate measurement over wide RH and T ranges. It
must not be applied in hazardous environment with agressive or flammable gases
or in explosive areas. For use outdoors and/or in meteorolgy, optional
radiation shields are available. Please refer to chapter 3 Product
Description. The use of the EE08 in any other way than described in this
manual bears a safety risk for people and the entire measurement installation
and is therefore not allowed. The manufacturer cannot be held responsible for
damages as a result of incorrect handling, installation, and maintenance of
the equipment. In order to avoid damage to the instrument or health hazards,
the measuring equipment must never be
manipulated with tools that are not specifically described in this manual. The
sensor may only be utilized in accordance with the conditions defined in the
technical data.
Otherwise, measurement inaccuracies will occur and equipment failures cannot
be ruled out. The steps recommended by the manufacturer for installation,
inspections and maintenance work must be observed and carried out for the
safety of the user and for the functionality of the equipment. User Manual

Product Description
General
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.
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).

The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling, installation, wiring, power supply and maintenance of the device.
Ground connection:
A low impedance connection between the shield of the connection cable and the
ground potential is important for the flawless operation of the EE08.
E2 Voltage Level:
Please observe an E2 voltage level of 3.3 V / ±0.1 V on the data lines.
Installation
The follwing mounting types are possible:
- Wall mount with the help of a mounting clip, available as accessory HA010211.
- Outdoor operation with radiation shield: wall mount or pole mount. Please mind the mounting instructions included in the manuals of HA010502 and HA010506.
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!
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.
