Technical background:
The philosophy behind NeuLog’s plug and play technology is based on each sensor’s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (
o
C,
o
F, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in software in the logger can be
upgraded for free at any time using the provided firmware update.
The sound sensor uses an internal microphone with a series of circuits, filters, and
amplifiers to best isolate a specific sound source. Sound waves enter through the
hole in the top of the sensor’s plastic body so you should point that directly towards
the sound source for best readings.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the sound sensor’s body.
After use, gently wipe away any foreign material from the sound sensor.
Store in a box at room temperature out of direct sunlight.
Warranty:
We promise to deliver our sensor free of defects in materials and workmanship for a
period of 3 years from the date of purchase. Our warranty does not cover damage of
the product caused by improper use, abuse, or incorrect storage. Sensors with a shelf
life such as ion selective proves have a warranty of 1 year. Should you need to act
upon the warranty please contact your distributor. Your sensor will be repaired or
replaced.
