Product Usage

Components
The Wireless pH Sensor comes with the following components:

pH Probe
pH Storage Solution (in storage bottle)
Storage Bottle Cap
BNC Connector (pH Probe)

pH Probe
The pH probe is used to measure the pH of a solution. It should be connected to the sensor using the BNC connector.

pH Storage Solution (in storage bottle)
The storage bottle contains a pH storage solution, which keeps the probe hydrated when not in use. Before taking measurements, remove the storage bottle from the probe.

Storage Bottle Cap
The cap can remain on the pH probe when the storage bottle is removed. Push the cap to the top of the pH probe when taking measurements.

BNC Connector (pH Probe)
The BNC connector is used to connect the pH probe to the sensor. To connect, push and turn clockwise until the connector locks into place.

Introduction

The Wireless pH Sensor measures the pH of a solution within a pH range between 0 and 14. The measurement is transmitted wirelessly via Bluetooth and displayed in PASCO Capstone or SPARKvue data collection software. The pH Sensor can also be used with alternative probes, such as the Oxidation Reduction Potential Probe (PS-3515) or a variety of Ion Selective Electrodes (ISEs).

Set up the hardware
Before taking measurements with the sensor, you must connect the pH probe to the sensor and remove the storage bottle from the probe.

Connect the pH probe to the sensor

Figure 1. Aligning the tabs on the BNC connectors.

Align the tabs on the sensor’s BNC connector with the slots on the probe’s BNC connector, as shown in Figure 1.
Push the probe’s BNC connector onto the sensor’s BNC connector.
Twist the probe’s BNC connector clockwise (when viewed with the probe connector facing away from you) about one-quarter turn to lock it into place.

NOTE
The Wireless pH Sensor also works with several alternative electrodes available from PASCO, including various ion selective electrodes (ISEs), the Oxidation Reduction Potential (ORP) Probe (PS-3515), and the Flat pH Probe .(PS-3514). See the Buying Guide on the product page for more information.

Remove the storage bottle

Hold the pH probe vertically so that the solution will not spill out of the bottle.
Unscrew the plastic cap and remove the bottle. Keep the storage solution for later use.
Push the bottle cap and rubber washer up the pH probe to keep them out of the way of the solution to be measured. (See Figure 2.)

Figure 2. Removing the storage bottle from the pH probe.

Placing the sensor in a solution
When taking measurements, place the end of the pH probe in a solution. Make sure that the bulb at the end of the probe is completely immersed in the solution.

IMPORTANT
Do not immerse the BNC connectors in the solution! The connectors are not rust-proof and can corrode from direct exposure to liquid. An Electrode Support (PS-3505) is recommended for holding the probe in place. The Wireless Drop Counter (PS-3214) can also be used to hold the probe.

Calibration

Calibration of the Wireless pH Sensor is not always necessary, especially if you are measuring a change in pH rather than absolute pH values. However, the sensor can be calibrated if more precise measurements are required. For instructions on calibrating the sensor, see the PASCO Capstone or SPARKvue online help.

Storage and maintenance

Cleaning the probe
For most applications, you can clean the probe using hot water with a domestic cleaning detergent. The following table contains specific cleaning recommendations for different types of solutions to which the probe may be exposed

Solution type	Recommended cleaning solution
Lime and hydroxides	5-10% hydrochloric acid
Organic fouling agents (fats, oils, etc.)	Rubbing alcohol or liquid dish soap
Algae and bacteria	Diluted chlorine bleach

Storing the sensor and probe
After each use, place the pH probe in the storage bottle filled with the storage solution. The bulb at the end of the probe must be fully immersed in the storage solution. Do not store the probe dry, as this will cause the probe to lose responsiveness. If needed, probe restoration instructions are provided online on the Wireless pH Sensor product page. Replacement pH Storage Solution (SC-3507) can be purchased if any solution is lost due to spillage or evaporation. If you wish to make your own storage solution, instructions are provided online on the Wireless pH Sensor storage page. When storing the sensor long-term, remove the battery from the sensor to avoid the risk of damage to the sensor in the event of battery leakage.

Replacing the battery
When the Battery Status LED blinks red, the battery is low on charge and will soon need to be replaced.

A: First mark.
B: Second mark.
C: Indicator.

Insert a coin into the battery compartment door. Turn the door counterclockwise until the indicator (C) is aligned with the second mark (B).
Remove the battery compartment door, O-ring gasket, and battery.
Insert a new CR2032 battery into the compartment, with the positive (+) side facing upward toward the door.
Insert the O-ring gasket into the compartment. Place the door on the sensor, aligning the indicator with the second mark. Turn the door clockwise until the indicator is aligned with the first mark (A).
