New at Tech2Have: FNIRSI oscilloscopes, multimeters, smart soldering irons, signal generators and USB testers — a guide to the full range and where each tool fits.
If you repair electronics, build prototypes, or maintain equipment, a workbench full of test gear used to mean a serious budget. FNIRSI changed that equation. The Shenzhen-based instrument maker has spent more than a decade building oscilloscopes, multimeters, soldering tools and testers that punch far above their price — and the full range has just landed at Tech2Have.
Who is FNIRSI?
Shenzhen FNIRSI Technology Co., Ltd. is a high-tech manufacturer dedicated to intelligent testing and measurement instruments, shipping well over a million units a year worldwide. Its design philosophy — simplicity, convenience, professionalism, efficiency — shows in every product: colour screens instead of cryptic segment displays, USB-C charging instead of wall-warts, and one-button auto functions that get a reading on screen fast. FNIRSI gear is a favourite among makers, hobbyists, field technicians and electronics students alike.
Oscilloscopes — from pocket to benchtop
The heart of the range. FNIRSI builds scopes at every size: the pocket DSO-152 for quick signal checks, the best-selling DSO-TC3 3-in-1 (scope + component tester + signal generator), the dual-channel DPOX180H digital phosphor handheld, tablet-style touchscreen units like the 2C53T and DPOS350P that fold in multimeter and generator functions, and proper benchtop instruments. Whatever your bandwidth and budget, there's a sensible step on the ladder.

Multimeters & clamp meters
FNIRSI's meters lean on big colour displays and smart auto-ranging. The DMT-99 and compact S1 cover everyday bench and field measurement, the DMC-100 clamp meter handles AC/DC current without breaking the circuit, and the TMP-610S packs a 60,000-count multimeter, scope and signal generator into one handheld.

Soldering & rework
The smart-soldering line is where FNIRSI has won the most fans. The HS-02 100 W USB-C iron heats to soldering temperature in seconds and is reviewed in depth in our HS-02 review. Around it sit the DWS-200 200 W station, the HT-P1 mini hot plate for reflow work, and the SAG-55 550 W intelligent hot-air gun — a complete rework bench that fits in a drawer.

Signal generators
From the pocket SG-003 to the dual-channel DPG-1122 (120 MHz arbitrary waveform) and the benchtop TSG6020, FNIRSI's generators cover function-generator duty for education, repair and design validation.

USB & battery testers
Small tools that save real diagnostic time: the FNB58 and FNB48P USB testers decode fast-charge protocols and log voltage/current, the FNB-C2 handles USB PD 3.1, the BTM-24 tests 12/24 V car batteries to 2000 CCA, and the HRM-10 measures cell internal resistance.

Specialty instruments
The range rounds out with genuinely useful oddballs — the GC-03 multifunction radiation detector and the SWM-10/SWM-20 portable battery spot welders for pack building and repair.
For field diagnostics, repair, education and maker work — yes. FNIRSI instruments trade the certification and last-digit precision of lab brands for a fraction of the price, which is exactly the right trade for most bench and field tasks. For calibrated compliance measurements you'd still reach for a lab-grade instrument.
For component-level repair and learning, the DSO-TC3 3-in-1 is the classic entry point. If you need real bandwidth for MCU and power work, step up to the DPOX180H (180 MHz) or a tablet model like the DPOS350P (350 MHz).
