Tech Tips

Why is the measured tip temperature lower than the set temperature?

Important points are maintenance of the soldering iron and measuring instrument and using the correct measurement method

Check 1Are the tip, element cover, nut, etc. oxidized?
Check 2Is the tip shape changed?
Check 3Has the sensor of the thermometer deteriorated? (In the case of HAKKO-manufactured contact-type measuring instruments)
Check 4Are the batteries low on power?
Check 5Is the correct measurement method suitable for the measuring instrument being performed?

Check 1. Are the tip, element cover, nut, etc. oxidized?

If the tip, element cover, nut, etc. are oxidized, heat conduction may be deteriorated, causing the measured temperature to be lower in some cases.

Replace them with new ones before measuring the temperature. If the temperature is still shown lower, confirm the details in Checks 2 through 5
