This pH measurement set for education provides everything required to measure and calibrate pH in classroom experiments and teaching laboratories. The set includes a reliable pH probe together with three NIST-traceable calibration buffers (pH 4.00, 7.00 and 10.00) and KCl storage solution to keep the probe in optimal condition.

Designed for practical demonstrations and student experiments, the kit allows teachers to introduce pH measurement, calibration and electrode care using professional laboratory standards. The three-point buffer system also enables students to understand how accurate pH measurements are established and maintained.

Perfect For

• Secondary school chemistry classes
• Environmental science lessons
• STEM education programs
• TAFE and introductory laboratory training
• Classroom demonstrations of the pH scale

What Students Can Investigate

Using this kit students can explore:

• acidity of everyday liquids
• the pH scale from acidic to alkaline
• how scientific instruments are calibrated
• neutralisation reactions between acids and bases
• environmental water testing experiments

These activities help connect theoretical chemistry concepts with real measurements.

Example Classroom Experiments

Students can measure the pH of:

• lemon juice
• vinegar
• soft drinks
• milk
• tap water
• baking soda solution

They can also observe how pH changes during acid–base neutralisation experiments.

Kit Contents
