Measure Inductance, Capacitance, Resistance and Impedance

  • Supports inductors, capacitors, resistors and arbitrary impedances.
  • Inductance from 0.0uH to 10H (min resolution 0.2uH).
  • Capacitance from 0.0pF to 10000uF (min resolution 0.2pF).
  • Resistance from 0.0 Ohms to 2MOhms (min resolution 0.2 Ohms).
  • Directly measure component values.
  • Measure complex impedance, complex admittance and Magnitude and Phase of impedance (Polar form).
  • Auto and manual modes for test frequency (DC, 1kHz, 15kHz and 200kHz).
  • Auto and manual modes for component type.
  • Works with polarised and non-polarised electrolytic capacitors in either orientation.
  • Easy to scroll through all the measurement types you need.
  • Continuous measurements with "hold" function. Great for fine tuning components.
  • 24 month warranty as standard.
It does more than you think
As you would expect from an LCR meter, the LCR45 is great for measuring your inductors, capacitors and resistors. However, this LCR meter offers much more. 

Simple to use
Just clip the universal test leads to your component and press the test button. In seconds, the LCR45 will identify the type of component (Inductor, Capacitor or Resistor) together with the components value. Readings are taken continuously, giving you the ideal tool for making fine adjustments. 

In addition to the component type and value, the LCR45 can also display the component's parameters as a complex impedance, complex admittance or magnitude and phase of impedance.

What's more, you can select auto and manual modes for both the component type and test frequency.

Flexible
The LCR45 is supplied with our new 2mm compatible detachable micro-hooks, allowing the use of a range of 2mm compatible probes.

LCR45 FAQs
  Can I measure the impedance of speakers? Yes, set the LCR45 to manual inductance mode and a fixed frequency of 1kHz or 15kHz. You can see the inductance, resistance, total impedance and phase of the impedance.  
When testing speakers at 15kHz, I can hear a low frequency buzz from the speaker, not the 15kHz I've selected. Why? The LCR45 uses "bursts" of test signals, it is these "bursts" that you can hear. During each burst, the LCR45 is using the test frequency you've selected.
Can I measure arbitrary impedances rather than just components? Yes. If the LCR45 has difficulty selecting the best mode and frequency then you can switch to a manual mode and test frequency to display the detailed impedance.
Can I use this in-circuit? No, it is not recommended for in-circuit use. Other component interactions can cause misleading results and damage may result from unexpected charged devices.
Is the LCR45 better than the LCR40 for low inductances? Yes. The use of a finer resolution ADC provides significantly finer measurements when measuring below 1H.
Is the LCR45 calibrated? Yes. Every LCR45 is individually calibrated to standards that are traceable to international standards.
What probes are included? Our universal gold plated hook probes (removable).
  Can it test polarised and non-polarised electrolytic capacitors? Yes. The tests are performed with very low voltages and will be fine for both polarised and non-polarised capacitors in either orientation.
