J Type Thermocouple Sensor with 1m Cable - Compoden
J Type Thermocouple Sensor with 1m Cable
The J Type thermocouple sensor uses an iron-constantan junction to measure temperatures from -40°C to 750°C with high accuracy. It comes with a 1 meter fiberglass insulated cable that withstands high temperatures. Suitable for industrial monitoring, scientific experiments, and DIY electronics projects.

Compatibility
This J type thermocouple generates a small voltage proportional to temperature. It requires a thermocouple amplifier such as MAX31855 (J-type variant) or AD8495 for direct interfacing with Arduino, Raspberry Pi, or ESP32. Works with any microcontroller that can read analog voltage with appropriate amplification.
Wiring Notes
The red wire is the negative lead and the other color (commonly white or blue) is positive. Connect to a thermocouple amplifier's input terminals, ensuring tight connections to avoid noise. For direct analog reading, a low-noise instrumentation amplifier is recommended.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, with a J-type compatible amplifier board like MAX31855 J-type module. Direct connection to analog pins is not possible without signal conditioning.
Can this measure temperatures above 750°C?
The maximum recommended temperature is 750°C for continuous use; exceeding this may damage the probe or reduce accuracy.
What is the difference between J type and K type thermocouples?
J type uses iron-constantan and has a higher output voltage but lower maximum temperature than K type. It is often preferred in older industrial equipment and for moderate temperature ranges.
