An Easy Method for Testing the Temperature Accuracy of a Soldering Tip
Need a fast, easy, way to find out if your digital soldering station readout is accurate? Try this. First, get the exact melting point of the solder you are using from the manufacturer's specifications. For example, the melting point of 100% tin solder is 450° F (232° C). Now, set the digital display of your soldering station to a temperature 10° F below the melting point and allow it to stabilize to that temperature. Next, increase the temperature of the pencil in one-degree increments while holding the solder wire against the tip. Continue to increase the temperature slowly until the solder reaches the melting point. When the solder begins to melt, you'll know you have reached the specified melting point of the solder, in this case 450° F. Compare that temperature with the digital readout. If the two numbers differ, you may want to set your station using the temperature-offset feature if it has one. This is a basic, easy way to check the temperature accuracy without using temperature-measuring equipment.
