Features of electric soldering iron thermometer
0.2m CA can accurately and quickly measure temperature, suitable for lead-free soldering.
The temperature of the welding nozzle can be measured at any angle according to its shape.
Equipped with an automatic shutdown function, the power will automatically turn off when not in use for 3 minutes
There is a [MAXHOLD] function to record the highest temperature of the welding nozzle. When the [MAXHOLD] button is pressed, the display screen will show the record of the highest temperature of the welding nozzle.
Accurately and quickly measure the temperature of the welding nozzle using a CA sensor.
Clear numerical display.
Special alloy coating enables the sensor to resist corrosion and oxidation.
Sensors are easy to replace.
The principle of electric soldering iron thermometer
The electric soldering iron thermometer is composed of a temperature sensing wire and an instrument. The temperature sensing line is a K-thermocouple that outputs a voltage signal, which is detected by an instrument and converted into a temperature value. Thus, accurate temperature can be displayed on the digital display screen.

The electric soldering iron thermometer is composed of a temperature sensing wire and an instrument.
If you have a digital multimeter that can measure temperature and the probe is a thermocouple, it would be very convenient. Because usually this thermocouple is also K-type, simply connect the output of the temperature sensing line to the temperature input of the multimeter! It directly displays the temperature.
If the digital multimeter in hand cannot measure temperature, then it can only use its 200mV range to measure voltage, and then check the meter to convert it into temperature value.
The temperature sensing line can be used with a white light 191 thermometer, as long as one is used. The temperature sensing wire is a consumable material that needs to be replaced after about 50 uses to ensure accuracy, so it is easy to purchase.
The temperature sensing wire is the trademark of Mercedes Benz, with a temperature sensing block in the middle that leads out three wires, and a circle at the end for connecting to the terminal. In fact, it is made of two wires, with the red wire being the positive wire and the blue wire being the negative wire. There is also an edge where these two wires are wrapped together and not used as a signal wire. It is mainly used as a support because only three edges can support it firmly.
The main job is to make a frame for the temperature sensing line.
Buy 3 terminal posts. When the thread of the terminal post is larger than the circle of the temperature sensing wire lead out, remove the small circle of the lead out wire and then wrap a large circle according to the thread size of the terminal post again.
