Product Category Description:

• Traceable™
• Available in 473 mL (16oz.) or Single-Use Sizes

These reagent grade solutions are compatible with all makes of equipment. Accuracy is ±0.25µmhos for 1, 5, and 10µmhos 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 473mL (16oz.) brown glass bottles or 100mL (3.4oz.) single-use polyethylene bottles.

Single-use standards make it easy to calibrate with no external contamination. An extra large opening of 4.4cm (13/4") diameter and depth of 8.9cm (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 certificate from an ISO 17025 calibration laboratory to indicate traceability to standards provided by the National Institute of Standards and Technology. Some solutions (as indicated) include a certificate from an ISO 17025 calibration laboratory accredited by A2LA.

Ordering Information: Assortment 61161-356 includes one bottle each of the single-use standards, excluding the 5µmhos solution (12777-832).
