PASPORT Charge Sensor - PS-2132



Measuring electrostatic charges is now simple and quantitative with our Charge Sensor. Think of it as a highly sensitive electroscope that isn't affected by humidity and indicates whether a charge is positive or negative. Great for other high-resistance voltage measurements too. Automatic scaling eliminates the need for a gain switch. Highly efficient input overvoltage protection makes it virtually blow-out proof, providing many years of student use.

  • No guessing if a charge is positive or negative – the polarity is shown.
  • Measures both charge and voltage.

Typical Applications

  • Measure charge by induction
  • Quantify the charge on a capacitor
  • Discover the charge distribution on a conducting sphere
