Sell Diagnostics & Calibration Tools for Cash in Boston, MA

This gear is graded on behavior, not looks: a scuffed Fluke that still reads true beats a spotless one with a dead display segment. Here is what gets looked at.

• Display - every LCD segment on a meter; on a scan tool, the touch layer and any dead zones.
• Input jacks and fuse - the 10 A and milliamp inputs, checked for a blown internal fuse or a banana socket that no longer grips a plug.
• Rotary switch - each detent should land cleanly on its range; one that skips volts or continuity is a real fault.
• Battery bay and boot - green corrosion from leaked alkaline cells, or a split rubber holster.
• Readings - a known voltage and a reference resistance, so drift shows up in front of you.

A discontinued analog meter, or a scanner whose update path ended several model years back, sits outside the select brands and models listed here even when it powers up.

Test equipment is priced as a kit. Leads, probes and paperwork go missing first, and they are what must be replaced before resale.

• Leads and probes - original silicone leads, clips and the bead thermocouple, rated to the CAT level printed on the meter body; nicked insulation counts as missing.
• Clamps and adapters - current clamps, high voltage probes, and on an Autel or other OBD2 scanner the adapter cables and vehicle interface box.
• Case and hanger - the molded case with foam cut-outs intact, plus magnetic hangers and the original holster.
• Calibration paperwork - a dated certificate or cal sticker on a Fluke, Triplett or Ideal instrument shows when it was last verified.
• Account status - a scan tool serial cleared from the previous owner's login, and any remaining software period visible on screen.

Sending photos ahead works best with the open case and the model plate in one frame; a complete kit prices faster than a bare instrument on a bench.
