As of December 31, 2014, TransTech will no longer repair the PQI Model 300, due to the unavailability of the electronic component parts used in this product. We are also not able to perform an upgrade on this equipment.

If your PQI 300 is still in good working condition and you wish to continue using it, please do so! TransTech will be able to perform annual calibration on the PQI 300, just not provide repair parts or service.

With this in mind, you may want to consider upgrading to the latest in the non-nuclear technology. The PQI Model 380 can help your company stay on track with your paving practices.

If you have any questions about the discontinuation of the PQI 300, or about the latest model PQI 380, please contact your local representative at 518-370-5558 or 1-800-724-6306.

We truly appreciate our past business with you, and look forward to our continue future together.
