9034 in stock


65275-9eef20.jpeg Thermometer RST FG-100 Soldering iron thermometer specifications: 0.2 mm CA sensor can accurately and quickly measure the temperature of the soldering tip, suitable for lead-free solder; tip temperature can be measured at any angle according to the shape of the tip.



  • Made of high quality material, durable and practical to use.
  • Soldering Iron thermometer provides reliable control of the soldering iron temperature.
  • Application of a thin CA linear sensor (φ0.2 mm) in order to get good temperature reactions.
  • When the thermometer is not used for 3 minutes, the power will automatically turn off.
  • Display 3.5-bit LCD display. Displays information about battery failure and sensor burnout.
  • Allows you to take measurements from any desired direction based on the shape of the pen tip.
  • Maximum Hold function: When the “Max Hold” button is pressed, “Max Hold” will be displayed and the maximum temperature of the iron will be held on the display.


  • The FG-100 thermometer provides fast, accurate tip temperature measurements using a fine CA wire sensor (ø0.2). The FG-100 measures tip temperatures as well as solder pot temperatures (with optional temperature probe.)
  • Lightweight, easy-to-replace sensors provide accurate measurement of tips for verification or calibration processes. When the MAX HOLD feature is enabled, the thermometer will display the maximum temperature measured.
  • To preserve battery life, the auto shutoff feature turns the thermometer off when not used for three minutes. The thermometer design allows for easy measurements from right or left handed operators.
