Hakko Soldering Iron Digital Multifunction Thermometer, K Probe, +700°C Max

The Hakko FG100B-71 is a precision digital thermometer engineered for accurate temperature measurement in soldering, rework, and thermal process environments. Designed with a K-type thermocouple probe and a measurement range up to +700 °C, it serves critical needs in industrial, electronics manufacturing, and repair applications. Features such as AUTO HOLD (locks reading when tip temperature stabilises) and MAX HOLD (captures the highest measured temperature) ensure consistent, repeatable results.

Unmatched Advantages of Buying the Hakko Soldering Iron Digital Multifunction Thermometer, K Probe

• Measures up to +700 °C for high-temperature soldering tip and pot applications.
• K-type thermocouple probe ensures stable, reliable sensing across wide temperature ranges.
• AUTO HOLD automatically captures an accurate result once the temperature stabilises, reducing operator variation.
• MAX HOLD function records the highest temperature achieved, proper for quality control.
• Supports calibration certificate option, delivering measurement traceability for regulated environments.
• Dual-unit display (°C/°F) and ergonomic design accommodate diverse user workflows.

Engineered for High-Temperature Electronics Production and Maintenance

The FG100B-71 is designed for environments where precise thermal measurement is critical, including lead-free soldering, hot-air rework, wave-solder monitoring, and pot temperature verification. Its low-inertia sensor rapidly captures temperature, and the AUTO HOLD feature ensures consistency by locking in the reading as soon as the surface stabilises. Combined with MAX HOLD and a rugged build, the device supports long-term process monitoring and maintenance cycles, reducing downtime and risk of thermal damage to components.

Versatility in Applications

• Measuring soldering iron tip temperature during PCB production or repair.
• Verifying solder pot or wave-solder bath temperature for process control.
• Monitoring the hot-air rework system nozzle output or the pre-heater plate temperature.
• Maintenance checks on power modules, thermal heads, or heating elements.
• Calibration/validation tasks in electronics manufacturing.
• Service-bench work in R&D or repair labs.
