Stop guessing your tip temperature. If your soldering station display says 350°C but your joints look dull and cold, the problem might not be your technique. Temperature drift happens over time, and even quality stations like Hakko, YIHUA, or KSGER units can fall out of calibration. The SUGON S-191 gives you the actual temperature at your tip in seconds.
This compact thermometer is built for electronics hobbyists, repair technicians, and anyone serious about consistent soldering results. Whether you’re doing delicate SMD rework on a Nintendo Switch, replacing capacitors on vintage audio gear, or building custom mechanical keyboards, accurate tip temperature directly affects joint quality.
Key Benefits
Accurate readings across your working range. The K-type thermocouple sensor delivers ±3°C precision between 300°C and 600°C, which covers most lead-free soldering work. Outside that range, accuracy stays within ±5°C. The 0.2mm fine wire sensor responds quickly to temperature changes, so you get reliable readings without waiting.
Measure from any angle. Unlike fixed-position thermometers, the flexible sensor lets you approach the tip from whatever direction suits its shape. Conical tips, chisel tips, knife tips—position the sensor where it makes contact and get your reading.
Built for real workshop use. The 3½-digit LCD display is easy to read under bench lighting. MAX HOLD locks the peak temperature on screen, so you can focus on positioning rather than watching numbers climb. Auto shut-off preserves battery life when you forget to turn it off.
Compatible with lead-free soldering. The sensor handles temperatures up to 700°C, well above what lead-free alloys require. No separate equipment needed for RoHS-compliant work.
What’s Included
- SUGON S-191 Tip Thermometer (70mm × 130mm × 40mm)
- 4 lead-free sensor sets
- 9V battery not included (standard 006P type)
Why Calibration Matters
Temperature accuracy determines joint quality. Too cold and solder won’t flow properly. Too hot and you risk pad lift, flux burn-off, or component damage. A £200 station means nothing if the displayed temperature doesn’t match reality. Professional repair shops verify calibration regularly. Now you can do the same at your home bench.
