Frequently Asked Questions
Q: What is the LF191AD Soldering Iron Tip Thermometer used for?
A: The LF191AD is a digital temperature tester designed to accurately measure the tip temperature of soldering irons and rework stations. It covers a range of 0–800°C (32–1472°F) using K-Type thermocouple sensors, making it ideal for electronics professionals, PCB assembly technicians, and hobbyists who need precise tip temperature data for consistent, high-quality solder joints.
Q: What does the MAX HOLD function do on the LF191AD thermometer?
A: The MAX HOLD function captures and locks the highest temperature reading recorded during your measurement session on the display. This is especially useful when you need to verify that an iron tip reached a target temperature momentarily — for example, when checking thermal performance or validating station calibration — without having to watch the screen continuously.
Q: How does the auto-shutdown feature work?
A: The LF191AD features a configurable automatic shutdown timer that powers the unit off after a set period of inactivity, helping to conserve battery life. You can adjust the shutdown time to suit your workflow. Simply turn the unit back on when you're ready to continue measuring — no re-calibration needed.
Q: Can I switch between Celsius and Fahrenheit readings?
A: Yes. The LF191AD includes a dedicated °C/°F toggle switch, allowing you to instantly switch the display readout between Celsius and Fahrenheit. This makes it versatile for users worldwide, regardless of their preferred temperature scale.
Q: What type of sensor probes are included with the LF191AD?
A: The kit includes 5× lead-free K-Type thermocouple sensor probes. K-Type thermocouples are the industry-standard choice for high-temperature measurement applications, offering a broad measurement range and reliable accuracy when placed directly in contact with a soldering iron tip.
