Used HP Test Equipment & Parts   Skip the INTRO, Go RIGHT to the CATALOG! HP Equipment: Hewlett Packard (now 'Agilent', BIG marketing mistake...) has been one of the major forces in the design of durable lab test equipment for decades. We have an assortment (regularly changing) of HP equipment, especially oscillators, counters and meters, as well as some new and used spare parts.
NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place! ORDERING: You can order anything here just by picking up the phone, and calling +1 (250) 769-1834 during normal office hours, 8am to 5pm, PST. We process VISA/MC orders immediately. You can also send your order by FAX at: +1 (250) 769-4106. Or, EMAIL YOUR ORDER HERE! SHIPPING: Canadian ExpressPost (NOT regular mail, this is like US Global Priority/Courier) Rates: To USA destinations, shipping and packing minimum of $23 for any insured, trackable air shipment up to 1kg (typical delivery within 5 business days), Canadian destinations are typically $10-14 (delivery within 2-3 business days). It is also possible to ship uninsured, untracked, small packets (250g max.) for roughly $12-14 to the USA, but delivery delays can be up to 8 weeks according to the US Postal Service, and so we cannot recommend it. Virtually all of our shipment failures have been because of this method, so it should be used with caution. We have an extraordinarily good success rate (better than 99.9%) with ExpressPost, so we highly recommend it, especially for one-of-a-kind items. It is cheaper than couriers, trackable, more reliable, fully insured and goes almost everywhere. Shipping/handling to Europe, Australia, South America and other overseas areas via Canada Post International ExpressPost air mail insured service or Canada Post International Air Service where ExpressPost is not offered is $51.00 for parcels up to 500 grams/1 pound. Shipping and packing via regular mail to these locales is $22.00 for parcels weighing up to 500 grams/1 pound. This service offers no guarantee, insurance or tracking and we then accept no liability for loss or damage. Transit times are unpredictable by this method. E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. We can also ship FedEx or UPS when time or weight is critical, and over-night FedEx P1 shipping is available. Note that our pick-up cut-off time is noon for FedEx. There is a packing charge for large equipment, see the FAQ for details. If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. If this is the first time you have dealt with us, you can phone (250) 769-1834 or FAX +1 (250) 769-4106 the billing info, or send it by the email link, as you prefer.  CONDITION: To answer your questions, YES, we completely check and inspect all used equipment, and do not offer any we feel is substandard. That gear is normally scrapped, broken down for parts, or may get offered as-is in the HOT DEALS section, with the unit's condition clearly identified. If there are any marks or detracting features, we clearly state them in the listing. Before shipment, we burn in the equipment for 24 hrs. again and re-check to be sure it is good prior to shipment.
