Application Notes

Here's how some of our customers used this product.

Verifying Heat Treating Profiles

The Background: Our customer provides heat treatment services to products across a range of companies. They need a way to provide documentation to their customers that products have received this treatment for the intensity and duration necessary.

The Problem: Heat treatments generally require very specific temperatures for a very specific amount of time depending upon the product being treated. Our customer wants to provide verification of this to their comers.

The Solution: We suggested the HOBO UX100-014M thermocouple data logger which provides high accuracy reading across time. Results can be easily communicated to other devices for report generation.
