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.
