- Do you have these items in stock?
Yes. To confirm an item is available, simply add it to the shopping cart.
- If the item appears in the cart, it means that we have it in stock.
- If we do not have the required quantity, a message will be displayed indicating how many items are remaining in stock.
- The shopping cart will not allow an order to be placed for an out of stock item.
- Is this item new or used?
The item description clearly states the condition of each item. Please take the time to read product listings and examine pictures carefully before ordering.
Many items are "new/surplus," which means that the item is unused,
in excellent physical condition, and may or may not include the original box and product documentation (as indicated in description).
New/surplus items were most often purchased as excess inventory from other companies.
- Is your equipment tested?
Yes, whenever possible. We perform basic tests on most components and equipment.
We are an electronics surplus dealer, and not a
test or calibration lab, so we are usually not able to test calibration or perform other complex tests.
Example 1, Programmable power supplies: We normally perform a load test throughout the full output range of our power supplies.
We are usually not able to test computer interfaces, fine accuracy of calibration, etc.
Example 2, Power semiconductors: In nearly all cases we perform basic tests of power semiconductors, including
low-power switching tests of IGBTs, transistors, and SCRs. We are generally not able to perform detailed tests of more complex devices
such as those incorporating integrated circuits.
If you have any questions about a particular item, please contact us.

We have a daily UPS and USPS pickup. Rates for these services are automatically calculated by our shopping cart. Shipping by
other methods is possible and sometimes required. For example, some large and heavy items must be shipped by freight.
Additionally, shipping by air freight carrier such as BAX Global is often the most economical option for shipping medium and
larger sized items overseas. Please email us for rate quotes for these services.
