Wireless pH Sensor

Description

Overview

This sensor measures the pH of a solution as discrete measurements or as a continuous reading. Use the probe to study water quality, test household solutions, or perform high-resolution acid-base titrations with ease.

1 Minimum # of data points with all measurements enabled, actual results depend on enabled measurements.

2 Continuous use in a connected state until battery failure, actual results will depend on sample rate, active measurements, and battery condition.

3 Logging until battery failure, actual results will depend on sample rate, active measurements, and battery condition.

* Normal classroom use is the sensor in active use for 20min/lab for 120 lab periods/yr.

Experiment Library

Perform the following experiments and more with the Wireless pH Sensor.
Visit PASCO’s Experiment Library to view all activities for this product.

An Acid-Base Titration

In this lab, students will use a drop counter and pH sensor to determine the concentration of a hydrochloric acid solution and an acetic acid solution by titration.

Modeling an Ecosystem

In this lab, students use a variety of sensors to explore the use of terrariums as a closed system for environmental studies and design methods for exploring the interrelationships of biotic and abiotic variables within ecosystems.

Water Treatment

In this lab, students use pH, conductivity, and turbidity sensors to demonstrate how water treatment processes such as filtration, flocculation, and sedimentation improve water quality.

Diffusion

In this lab, students investigate the diffusion of ions through a semipermeable membrane using apple cider vinegar and a pH sensor.

Sunlight and Photosynthesis in Aquatic Plants

In this lab, students will use pH sensors to demonstrate the relationship between photosynthesis and light.

Determining Soil Quality

In this lab, students use carbon dioxide, conductivity, and pH sensors to determine the quality of different soil samples.
