Outdoor microphone protection kit
The
SA 277
outdoor microphone kit protects the
SVAN 977 preamplifier and microphone from weather
conditions. The use of the outdoor kit requires an
extension cable between the instrument and its
preamplifier (
SC 277
). The SA 277 is made of
lightweight materials and is easy to install on a tripod.
This solution is recommended for short term and semi-
permanent noise measurements in the environment.
The outdoor microphone kit has ¾” screw on its bottom
which enables using of standard tripods or other user
specific mountings. Technical data such as direct and
frequency
characteristics
associated
with
the
microphone are included in the SVAN 977 user
manual.
Optionally you may use desiccator - Silica gel.
Desiccator absorbs moisture normally contained in
the air.
Note: Desiccator should be regenerated
after some period of use, when it changes
colour to light grey, by drying it for 3 hours
in a temperature of 150°C. Desiccator
should be inspected at least every 2 weeks,
and more often when used in conditions of
high air humidity.
