No description available.
An IR-sensitive phototransistor is used to sense soldering-iron temperature. The phototransistor must see the tip through an opaque tube to avoid stray light, and the phototransistor should preferably be fitted with an IR filter. An old photo negative, dark red plastic, or red or black glass can be used. The iron sits on a holder.
