Peak Atlas LCR40 Passive Component Analyzer

Peak ElectronicsSKU: LCR40

$ 115


The Atlas LCR40 is an advanced instrument that greatly simplifies the testing of passive components. Traditional LCR bridges are inherently complex and very time consuming to use. The Atlas LCR does everything automatically, it tells you the component type in addition to component value data. What's more, the Atlas LCR automatically selects the best signal level and frequency for the particular component under test. Just clip the universal test leads to your component and press the test button. In seconds, the Atlas LCR will identify the type of component (Inductor, Capacitor or Resistor) together with the component’s main value. Additionally, further component data is also displayed, such as the DC resistance of an inductor. The test frequency is automatically selected to suit the component under test and this is also confirmed on the scrollable display. The Atlas LCR is supplied with our new detachable micro-hooks and clip probes, which also allows the use of the optional SMT Tweezers to probe surface mount devices or Gold Coated Croc clips. Supplied fully assembled, tested and aligned This is an indispensable piece of test equipment for a system designer or product technician!
