## Questions & Answers

**Q: Will these work with max31855 board or max6675 board?**
A: It doesn’t work well with max31855 or at least mine didn’t. I believe this thermocouple has ground connected to the sleeve so it worked in open air but when I inserted it into to the heater block my temp reading wasn’t consistent or anywhere near correct. (Pulled it out and worked liked it should.) 

I switched to an AD8495 and reading the analog signal from this TC works great.

**Q: would I need that amplifier for this when using my ender 5 plus ?**
A: yes, please check this ASIN: B08C4Z9PZS

**Q: what's the beta value of this thermocouple?**
A: This is K type thermocouple. If you need to source K type thermocouple amplifier, please search the ASIN: B08C4Z9PZS. About the firmware setting, please check the following:
Marlin2.0:
choose “-4”in the Temperature sensors settings
#define TEMP_SENSOR_0 -4
and make change in \Marlin\src\module\temperature.cpp 
 
for mega2560 such as ramps1.4  5V 10bit ADC 
//#define TEMP_AD8495(RAW) ((RAW) * 6.6 * 100.0 / 1024.0 / (OVERSAMPLENR) * (TEMP_SENSOR_AD8495_GAIN) + TEMP_SENSOR_AD8495_OFFSET)
#define TEMP_AD8495(RAW) ((((RAW) * 5.0 / 1024.0 / (OVERSAMPLENR)) / 0.005 / (TEMP_SENSOR_AD8495_GAIN)) + TEMP_SENSOR_AD8495_OFFSET) //for 5V 10bit ADC
 
for LPC1768 or otehr 32bit MCU which  analog input is 3.3V 12bit ADC 
//#define TEMP_AD8495(RAW) ((RAW) * 6.6 * 100.0 / 1024.0 / (OVERSAMPLENR) * (TEMP_SENSOR_AD8495_GAIN) + TEMP_SENSOR_AD8495_OFFSET)
#define TEMP_AD8495(RAW) ((((RAW) * 3.3 / 4096 / (OVERSAMPLENR)) / 0.005 / (TEMP_SENSOR_AD8495_GAIN)) + TEMP_SENSOR_AD8495_OFFSET)  //for 3.3V 12bit ADC
 
·Repetier:​​
please choose Temperature sensor:
AD8494,AD9485,AD8496,AD8497 5mv/℃

**Q: will this work with a pt100 amplifier/booster ?**
A: No, my friend

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works great!
  

*by A***R on Reviewed in the United States on 25 January 2023*

Using this in my Flashforge/Makerbot clone which uses thermocouples instead of thermistors.  Seems to be working great.  Love the spring at the sensor to provide strain relief and protection from the hotend.

### ⭐⭐⭐⭐⭐ 







  
    Gute Qualität
  
  

*by J***N on Reviewed in Germany on 26 March 2023*

Ich habe den T-K500 in einem Dragon Hotend im Einsatz bin bin super zufrieden. Er macht seinen Job und die flexible Leitung lies sich leicht verlegen.

### ⭐⭐⭐ 







  
    Guter THERMOCoupler aber ich finde den Preis zu teuer.
  
  

*by A***S on Reviewed in Germany on 20 January 2023*

Der Coupler ist perfekt für meinen 3d Drucker,aber meines Erachtens viel zu teuer,deswegen auch nur 3 Sterne
