LCR-Reader-MP Introductory Video

Instant Evaluations With Just One Touch

The LCR-Reader line was created as a budget friendly alternative to identifying and testing components. The lightweight device is able to determine the type of component and best test parameters to use with just a touch; simply grasp a component in the tips and the device will do the rest.
All measurement values, including the main and secondary impedance values (ESR) are instantly available on the bright OLED display on the device.

The Full Range of LCR-Reader Devices

The LCR-Reader line of handheld multimeters has expanded since the beginning in 2014. These devices include a budget model that doesn't compromise on basic accuracy - the LCR-Reader, to more extensive devices with higher accuracy and a plethora of features - the LCR-Reader-MPA.

Coming Soon: LCR-Reader-R2: a new model based on the MPA with 250 kHz test frequency and Analog Signature Analysis
