Introduction
The Wireless pH Sensor measures the pH of a solution
within a range between 0 and 14 pH. The pH of a solution
is a numeric scale used to specify the acidity or alkalinity of
an aqueous solution. The pH of pure water is 7, the pH of
an acidic solution is generally between 7 and 0, and the pH
of a basic solution is generally between 7 and 14. The pH
measurement is transmitted wirelessly through
and recorded and displayed by the PASCO
software on a connected wireless device such as a tablet or
computer. The Wireless pH Sensor is powered by a
replaceable three volt coin cell battery (included) and is
well-suited for continuous recording and discrete
measurements. The sensor is designed to optimize the
battery usage time.
Since each sensor has a unique Device ID number, more
than one can be connected to a computer or tablet at the
same time.
The pH Sensor can also be used with alternative probes,
such as Ion Selective Electrodes (ISE) and the
Oxidation-Reduction Potent (ORP) Probe. (See Alternative
Probes, page 4.)
The pH sensor housing is water resistant (depth of 1 meter
in water for 30 minutes). However,
immersing it in water or
other fluids may cause a loss of wireless connection
. Put
only the end of the included pH Probe into the substance
being measured.
ON/OFF Information
To turn the sensor on, press and hold the ON button
temporarily until the status LEDs start blinking. To turn the
sensor off, press and hold the ON button for a moment until
the status LEDs stop blinking. The sensor puts itself to
sleep after a period of about one hour of inactivity if
connected, and several minutes of inactivity if not
connected.
