No calibration required

Thanks to the con­stant phys­i­cal char­ac­ter­is­tics of Weller heater de­signs (Power Re­sponse / Sil­ver Line / Ac­tive-Tip tech­nol­ogy), there is not need for the cal­i­bra­tion of sol­der­ing sys­tems. The high-qual­ity sen­sor and con­trol tech­nol­ogy en­sure con­tin­u­ous tem­per­a­ture ac­cu­racy and sta­bil­ity in com­pli­ance with IPC J-STD-001. A cal­i­bra­tion is not re­quired.

Weller sys­tems fea­tur­ing Power Re­sponse / Sil­ver Line / RT-MS Ac­tive-Tip tech­nol­ogy 
Tem­per­a­ture ac­cu­racy J-STD-001 F    = +- 10°C / +-18°F      

This is also pos­si­ble with Weller prod­ucts!
If you re­quire a tem­per­a­ture ac­cu­racy in ex­cess of the IPC stan­dard, the ad­van­tage of Weller tools is that you can have this con­fig­ured using our fine ad­just­ment op­tion. 
On re­quest, we will be happy to issue a cal­i­bra­tion cer­tifi­cate (for a small fee to cover our costs).
