We will remind you

We will send a reminder two months before your RTI product is due for calibration. This lets you plan carefully when to send in your product to the RTI lab.

Express Service

Keep your meter up-to-date

When we calibrate your meter, we also ensure it gets all the latest updates for new X-ray equipment. This means your meter is kept up-to-date and that you get the most value out of your investment!

Upgrade Red Piranha to Black Piranha (R2B)

Get more value out of your Red Piranha by letting us upgrade it to a state-of-the-art Black Piranha. We believe in offering upgrade paths and are hesitant to discontinue products and service programs.
