Identify the exact model and options.
Two instruments in the same family can differ in bandwidth, frequency, channels, modules and installed options. List the model exactly as marked and separate configuration facts from assumptions. For DAQ and modular systems, describe the chassis, controller and modules together while keeping their individual identities.
Record condition with its evidence.
Power-on, a functional check and calibration are different observations. Record known errors, display condition, missing controls and last known use. Include service or calibration documents if available, with their actual dates. Do not treat expired calibration as current or describe an untested instrument as working based only on a display photograph.
Keep accessories and matched components visible.
Probes, leads, fixtures, interface cards, controllers, power supplies and cooling can affect usability. Photograph them together and identify what is missing. Software or a license may have separate transfer conditions; do not assume it can be supplied simply because a computer is present.
Demand is different from an asking price.
An online listing does not prove that equipment sold at the displayed amount. Compare the exact configuration, condition, included support and whether a result is a listing or an actual sale. Retail resale and a direct bulk purchase also involve different testing, holding, repair and selling work.
Include the cost of completing the project.
Lot size, site access, disassembly, packing, freight and equipment checks affect a proposal. An asset with useful parts may still cost more to remove than a similar item already packed at a loading dock. Review the inventory and practical work together rather than assuming one universal price formula.
Compare proposals on the same basis
Before comparing two offers, check that both include the same serial-number list, accessories and removal work. One proposal may include packing while another assumes the seller supplies packed equipment. Ask each buyer to identify exclusions and deductions. The useful comparison is the agreed transaction and remaining work, rather than the largest number in an email.
How Surplus Cascade determines a purchase price.
We consider condition, completeness, demand, volume, disassembly and transport costs. Final pricing is determined only after equipment checks. Photos start the conversation; they do not establish a final offer. Payment is by wire transfer after the transaction price is agreed.
Prepare the inventory checklist, review test and measurement equipment we consider and sell directly to Surplus Cascade. Faulty and incomplete assets can be reviewed within the accepted categories.
