NEULOG PH SENSOR GUIDE
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).
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 sensor
needs to be calibrated to pH 7 prior to initial use. Please review the “Sensor
Calibration” guide in the beginning of this document for detailed instructions.
The built-in software in the logger can be upgraded at any time using software.
The pH electrode houses a sensitive glass bulb which detects the H+ concentration in
the fluid being tested which 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 then is
calculated and translated back into pH.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the pH sensor‟s body.
After use, gently wipe away any foreign material from the pH 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
