One sure way of saving money when buying test equipment is to look at the second-hand used market. At many test equipment suppliers you will find major names and top quality machines on offer and with a little research and patience you can find yourself picking up an excellent bargain for a fraction of the cost of purchasing brand new testing equipment.
Just what are the processes that test equipment suppliers go through to ensure that they are selling on, reliable, quality equipment?

All reputable suppliers of used testing equipment will acquire their equipment from local, national and even international reliable businesses. Many used equipment suppliers attend auctions, or develop relationships with the original suppliers who may be selling on stocks of older models or surplus equipment. Quite often testing equipment can be purchased from government agencies and departments or as the unfortunate result of company liquidations.
Inspection and testing
Second hand and used suppliers usually carry out a sixteen point test program on all pieces before they are re-sold to ensure that they are in perfect working order. Once purchased all used test machinery undergoes a series of evaluations, inspections and tests to assess its capabilities and to determine the condition and functionality of the apparatus and to see if there is any necessity for repairs or parts replacement and to carry out a general cleaning and any essential maintenance work.
After assessing the units performance engineers will carry out any repair work or parts replacements that are necessary to ensure the product meets the manufacturers specifications and that it performs in the field as required.
All used test machines are also given a complete refurbishment, cleaned thoroughly and all minor scratches and dents ironed out so that it will appear as good as new.
Testing devices such as oscilloscopes, laser levels and tensile strength testers will all receive professional calibration to ensure that they produce accurate results and work to the expected standards. Calibrated equipment also receives a certificate proving their accuracy and a report of all works carried out before re-sale.
For many companies the use of second hand equipment is an ideal way of assessing a particular model or apparatuses “fit for purpose.” Companies are able to decide whether the equipment produces the kind of test results required for a specific project before electing to buy a brand new, top of the range model. It also proves useful if the project or results are for a unique, one-off venture.
