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 (for
example: oC, oF, Lux, %, ppm).
Building the conversion formula of the pH sensor is done
by measuring at least 3 different pH level buffers.
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. In spite of that,
the probe needs to be offset to pH 7 prior to initial use;
please review the "Sensor offset" guide at the beginning
of this document for detailed instructions.
The pH electrode houses a sensitive glass bulb which
detects the H+ concentration in the fluid being tested;
this is then translated to a voltage reading and passed
along a silver-chloride wire. The voltage reading is
compared with the second component, the reference
electrode to compare voltage differences. The voltage
reading is calculated and translated back into pH.
