One-Shot Traceable(reg) conductivity calibration standards eliminate external contamination by performing calibration in the standard's vial. The standards accommodate virtually all conductivity probes, and are targeted for use in field or lab conditions. The standard has a 1 3/4-inch diameter and 3 1/2-inch depth, which allow probe calibration to take place in the standard's polyethylene container. Each bottle is labeled for calibrating conductivity, resistivity, and dissolved solids.

Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
