The PASCO Promise of Learning

90-Day Satisfaction Guarantee

We are confident that PASCO solutions will help your students achieve more success in science education. However, if you are not satisfied that your students are more engaged and learning more effectively, you may return your purchase for a full refund within 90 days of purchase. We do not want you spending precious budget dollars on something you won't use. Certain exceptions apply, such as software that has been opened, digital downloads, e-books, and radioactive sources. These items may not be returned for credit. See instructions for Returns at the bottom of this page.

5-year Warranty for Education

Unless otherwise stated, PASCO-branded products are covered by a 5-year limited warranty from ship date against defects in material and workmanship. The PASCO warranty does not extend to any product containing a touch screen, products that have been subject to abuse, neglect, accident, and improper installation, or products that have been repaired or altered outside of our factory. Consumables and limited-life products (such as pH probes, ezSamples, membranes, fast-response temperature probes, batteries, chemical solutions, software, printed materials, etc.) are excluded from the 5-year warranty, but they do fall under the 90-day Satisfaction Guarantee. Product-specific and additional warranty information is available upon request.
