The FNIRSI range includes logic analyzers such as the DLA-16 Plus and DLA-32 Plus, designed for capturing and decoding digital signals, including communication bus diagnostics. The manufacturer also develops signal generators, including the SG-002 and SG-003A, for simulating voltage and 4–20 mA current signals in control and automation systems. Electronic component measurements are supported by LCR meters and component testers, including the LCR-T4, LCR-T7, LCR-TC1, LCR-P1 and LCR-ST1 tweezer-style meter for SMD components. These instruments support identification and testing of resistors, capacitors, inductors, diodes and selected semiconductor devices.
FNIRSI USB Testers, Radiation Detectors and Other Meters
FNIRSI manufactures USB testers such as the FNAC-28, FNB38, FNB48S and FNB58 for measuring voltage, current and power, and analyzing fast-charging protocols. The range also includes radiation detectors such as the GC-01, GC-02 and GC-03 for ionizing radiation measurements, and the ERD-10 for measuring electromagnetic fields and RF radiation. The other meters category includes instruments such as the HRM-10 battery internal resistance meter and the CTG-20 coating thickness gauge. FNIRSI also offers distance measurement instruments, including the IR40 laser distance meter, as well as WD-01 and WD-02 wall scanners for detecting hidden wires and other objects.
FNIRSI Laboratory Power Supplies, Soldering Stations and Tips
The manufacturer's workshop equipment includes FNIRSI laboratory power supplies, such as the programmable IPS3608 with adjustable voltage and current for testing electronic circuits. The range also covers soldering stations, including the 200 W DWS-200 and SAG-55 and SAG-55 PRO hot air devices for electronic component assembly and removal. For mobile work, FNIRSI offers portable soldering irons such as the HS-01 and HS-02, powered via USB Type-C and equipped with adjustable temperature control. The selection is complemented by replaceable soldering tips, including B2, BC3, ILS, KR and K65 variants, soldering stands and the SWM-10 spot welder for joining metal strips, including during battery pack assembly.
FNIRSI Applications in Electronics and Servicing
FNIRSI instruments are used for analog and digital circuit diagnostics, prototype commissioning, electronic equipment maintenance, and testing components and power supplies. Oscilloscopes and logic analyzers support signal analysis, multimeters and LCR testers assist with fault identification, and signal generators simulate signals used in automation systems. Radiation detectors and specialized meters extend the range of measurements beyond conventional electronics applications. Power supplies, soldering irons and hot air stations support circuit assembly, testing and repair in workshops, laboratories and educational facilities. Selecting suitable instruments requires consideration of the specifications of individual models, particularly measurement ranges, accuracy, bandwidth and permissible input signal levels.
