Customers may cancel orders for standard Products (subject to fair charges for Seller’s expenses including handling, inspection, restocking, and freight), provided that customer returns such Product to DSTech at customer's expense within ten (10) days of delivery and in the same condition as received.  Custom Products are non-cancelable and non-returnable. Since ObservAir sensors are configured for each customer's particular needs, all ObservAir units are considered custom Products unless otherwise stated by a DSTech representative. Standard products include enclosures and other accessories. 

​

Please see Terms and Conditions of Sale for details. All DSTech products come with a twelve (12) month limited warranty.
