Single-use standards eliminate concern about external container contamination. Calibration is made in the standard’s vial. Fits all probes. Extra-large opening (13/4-inches diameter) and extra-large, 31/2-inches depth allow probe calibration to take place in the standard’s polyethylene container. One-Shot™ Traceable® standards accommodate virtually all conductivity probes and are ideal for lab or field conditions.

One-Shot™ Traceable® Conductivity Calibration Standards are the most accurate available: ±0.25 micromhos for 5 and 10 solutions; other solutions are ±0.25% or the uncertainty shown on the certificate, whichever is greater. Standards are 100 percent compatible with all makes of equipment. Each bottle is labeled for calibrating conductivity (micromhos), resistivity (ohms), and dissolved solids (parts per million). Traceable® to NIST for accuracy. Supplied with individual serial-numbered Traceable® Certificate and individual temperature compensation chart. Supplied as a pack of six One-Shot™ Traceable® calibration standards. Each standard contains 100 milliliters.
