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 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/550592929-polisi3d-3d-printer-t-k500-m3-x-15mm-k-type](https://www.desertcart.tn/products/550592929-polisi3d-3d-printer-t-k500-m3-x-15mm-k-type) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-09*
