## Questions & Answers

**Q: Have nist traceable certificate?**
A: sheeeeeet.  Do YOU have a "nist" traceable certificate?

**Q: I need to know the manufacturing date of what I am purchasing, as these items dry out over time.  What is the lot#? This has the date.**
A: Greetings, 

I understand you're looking for a Lot # for your Thermomelt Temperature Indicator.  The date on the product is the Lot #, for example, if the indicator states LOT NO 061021.  That states that the product was manufactured on 06/10/2021.  

If you should have any further questions, please reach back out.

**Q: Can you use these to see when metal cools to a certain temperature by watching the melted mark resolidify?**
A: Not really. It will not turn back to a chalky solid state it was. It will melt to a puddle, then basically dissipate.I buy several temperature ranges and insure I am between, say 180 and 200, or 200 and 225.....

**Q: Is this suggested for marking at 660°F piping at oil refinery?**
A: The marker you asked about will melt at 650F and higher. So a mark on a pipe will tell you the temperature is a least 650F but you won’t know the exact temperature.  You could also buy markers for other temperatures.
