Traceable® Conductivity Calibration Standards

Traceable to NIST for accuracy
Standards calibrate all conductivity meters and probes for maximum accuracy. Traceable® Conductivity Calibration Standards are the most accurate available. Accuracy at 25°C is ±0.25 micromhos for 1, 5, and 10 micromho solutions and ±0.25% for other solutions or the uncertainty shown on the certificate, whichever is greater. Standards are 100% compatible with all makes of equipment.

Traceable® Bottles
To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology). Each bottle is labeled for calibrating conductivity (micromhos), resistivity (ohms), and dissolved solids (parts per million). Individually tested bottles are available from our ISO 17025 calibration laboratory accredited by A2LA. Supplied complete, each bottle comes with step-by-step calibration instructions, traceability information, individual temperature compensation chart, and Traceable® Certificate. Supplied in a 16-ounce glass bottle.

Traceable® One-Shot™
Single-use standards calibrate all conductivity meters and probes for maximum accuracy. One-Shots™ eliminate concern about external container contamination. Calibration is made in the standard's vial. Fits all probes. Extra-large opening (1-3/4-inches diameter) and extra-large, 3-1/2-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. Standards are 100 percent compatible with all makes of equipment. Each container is labeled for calibrating conductivity (micromhos/millisiemens), resistivity (ohms), and dissolved solids (parts per million). ). Supplied with temperature compensation chart. Supplied as a pack of six One-Shot™ Traceable® calibration standards. Each standard contains 100 milliliters.
