Product description: Multifunctional LCR tweezers meter for SMD components - FNIRSI LCR-ST1
The FNIRSI LCR-ST1 is a modern tweezers LCR/ESR meter designed for convenient testing of small electronic components, especially SMD (surface-mount) components . The device automatically recognizes the type of component being tested and displays both the main measurement value and auxiliary parameters such as ESR , dissipation factor D , quality factor Q , impedance Z , and reactance X. The meter supports three test frequencies: 100 Hz , 1 kHz , and 10 kHz , as well as test voltage levels of 0.3 V and 0.6 V RMS , allowing you to match the measurement conditions to the component's characteristics. The 1.14-inch HD color screen presents data clearly, and the ergonomic design of the tweezers facilitates measurement of components in hard-to-reach places. Thanks to the built-in 250 mAh lithium battery, USB Type-C charging and a low weight of 41 g , FNIRSI LCR-ST1 is a convenient tool for work in the field, service and laboratory.
Multifunctional tweezers LCR meter for SMD components - FNIRSI LCR-ST1.

Quick testing of SMD components
The tweezers-style design of the meter makes it easy to grip and measure small surface-mount components without the need for additional fixtures. Automatic component identification allows you to quickly check the parameters of resistors, capacitors , and inductors without manually switching modes . This solution speeds up work during PCB servicing and quality control in electronics production. The FNIRSI LCR-ST1 can be used for, among other things:
- diagnostics and testing of SMD components on PCBs
- consumer electronics and electronic devices service
- quality control of components in electronics production
- laboratory and educational work in the field of electronics
- quick identification of resistor, capacitor and coil parameters
A clear, 1.14" color display shows measurement parameters.
