LOG-HC2 Wireless Temperature/Humidity Data Logger for
Rotronic AG Hydroclip HC2
Handling
The logger consists of the electronics (housing model dependent: Stainless Steel or Plastic,
20x160 mm) and the HydroClip2 HC2 sensor (very high precision sensor, integrated or
separate cable) from Rotronic AG. The sensor head can be replaced, different variants are
available.
Please note: The HC2 sensor is not included, because
different versions exist.
Important: The sensor is protected against dust and
can withstand condensed water, but should not be
exposed to liquid water.
If the enclosure must be opened (e.g. for battery
replacement), please check the o-ring (sealing) very carefully! Use lubricant (to protect the
o-ring) before reassembling.
We recommend to lubricate the enclosure additionally after reassembling and before using in
the field (e.g. by Spray Vaseline). Please ensure, that no force affects the connector
sensor<->logger in the field.
About the range: Optimal range (line of sight in open environment) could be up to 300 meters
for loggers with separate antennas. If the sensor cable (if applicable) is used as antenna, a
range of 100 meters is realistic, for plastic housings with internal antenna, 30 meters are
realistic. In the 2nd case the first 20 cm of the sensor cable are mostly important for the
transmission. On request, special beam antennas with very high gain are available from us.
Please note: The devices are available with several different radio frequencies, depending on
the local regulations of the country (e.g.: 433 MHz in Europe, parts of Africa and Asia, 905
MHz in USA and Canada, ...). It is in the responsibility of the user, not to use devices that are
not allowed in the country of usage.
