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.
