Traceable® Conductivity Calibration Standards
By Control
Use with any meter
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 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.
Individually serial-numbered Traceable® Certificate is provided from our ISO 17025, A2LA accredited calibration laboratory for complete documentation. It indicates 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). 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.
