I recently upgraded some equipment and no longer need the DMM Check I have. It was manufactured by VoltageStandard.com and only purchased in mid-March of this year. It has very light use and has lived when not in use in an antistatic bag. This model has the upgraded option of 10ppm resistors. New from the manufacturer this unit goes for $38.50 plus freight. I am offering this unit for $20 including basic freight to anyone in the US (sorry, don't want to deal with the hassle of customs). Comes with original paperwork and even the original antistatic bag.
First to PM me with their email address will get a PayPal invoice sent to them. Pay within 24 hours and the item is yours.
