Specifications
About this item
These Certified Reference Materials (CRM) calibrate conductivity meters and probes for maximum accuracy.
- Traceable
- Available in single-use (100 ml) or 473 ml (16 oz.) sizes
- Easy to calibrate
- Polyethylene container
- Ideal for both laboratory and field conditions
They are compatible with all makes of equipment, and can be used in laboratory or field.
Single-use standards make it easy to calibrate with no external contamination. An extra large opening of 4.4 cm (1³/₄") diameter and depth of 8.9 cm (3¹/₂") allow probe calibration to take place in the standard’s polyethylene container. Ideal for lab/field conditions.
All solutions include a serial numbered Traceable certificate to indicate traceability to standards provided by the National Institute of Standards and Technology (NIST). Double A2LA accreditation accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy. CRMs are produced by A2LA accredited ISO Guide 34 certified reference material producer and by an A2LA accredited ISO 17025 calibration laboratory. Additional accreditations include ISO 31 (certificate content), and ISO 35 (statistical analysis), plus ISO 9001 DNV (certified quality manufacturer).
Accuracy at 25 °C is ±0.25 µmhos for 1, 5, and 10 µmhos solutions, and 0.25% for all other solutions; or the uncertainty shown on the certificate, whichever is greater. Each container is labeled for calibrating conductivity in micromhos (microsiemens), resistivity in megohms, and dissolved solids in ppm. Available in 100 ml (3.4 oz.) single-use polyethylene bottles or 473 ml (16 oz.) bottles.
